Chapter Text
The fish-and-chip shop smelled of vinegar, fryer grease, and damp wool.
Rain crawled down the window in crooked lines. The fryer hissed steadily while the radio behind the counter muttered through static.
Luke sat in the corner booth with his back to the wall.
K-9 was parked beside him on the tiled floor, head unit angled toward the door. Every time someone came in, the sensors tracked them with a soft mechanical whirr.
Luke looked like someone who had stopped believing in sleep.
Dark leather jacket. Laptop bag at his feet. Hair a little too long, a little too untidy. A tray of chips sat in front of him that had cooled into something more theoretical than edible.
Rani slid the vinegar bottle toward him.
“You’re doing it again.”
Luke blinked.
“Doing what?”
“Interrogating your dinner.”
Clyde didn’t look up from his cod.
“That chip has been under investigation for twelve minutes.”
Luke picked one up, considered it, then ate it.
Rani leaned forward.
“You can’t just leave Bannerman Road locked up forever.”
“I can.”
“You’re sleeping on Clyde’s couch.”
“It’s a functional couch.”
“It’s a weapon,” Clyde said. “There’s a spring in it that has vendettas.”
Luke shrugged.
“I’ve mapped the pressure points.”
Rani sighed.
“You’re supposed to be finishing your degree.”
“I am finishing my degree.”
“You haven’t been to campus in months.”
Luke wiped vinegar off his fingers with a napkin.
“I can teach most of the modules myself.”
“That is not how university works.”
“It could be.”
Clyde raised a fork.
“I would attend Luke University.”
Luke ignored him.
Rani folded her arms.
“You can’t just disappear into Clyde’s living room.”
“I haven’t disappeared.”
“You absolutely have.”
Luke glanced toward the rain-streaked window.
“I’m avoiding complications.”
“That,” Rani said, “is a very fancy way of saying hiding.”
Luke met her eyes.
“UNIT confiscated a supercomputer from my house.”
“That was months ago.”
“They took Mr. Smith.”
The fryer hissed.
Clyde slowed down chewing.
Rani’s voice softened slightly.
“They secure alien technology. That’s their job.”
Luke leaned back in the booth.
“Yes.”
“But the new head of UNIT isn’t like the old lot.”
Luke didn’t respond.
Rani brightened a little.
“I looked her up.”
Luke’s expression suggested that was not encouraging.
“She’s the Brigadier’s daughter.”
Clyde blinked.
“Wait, the Brig?”
“Yes,” Rani said, pleased with the research. “Kate Stewart. Alistair Gordon Lethbridge-Stewart’s daughter.”
Luke picked up another chip.
“Being related to someone admirable does not automatically guarantee competence.”
“Oh come on.”
Luke shrugged slightly.
“The Brigadier trusted people based on what they did, not who they were related to.”
Clyde gestured with his fork.
“Statistically speaking the Brig’s daughter is unlikely to steal your laptop.”
Luke didn’t smile.
“They took Mr. Smith.”
“They secured alien technology.”
“They took him.”
K-9’s head turned toward the door as someone walked in.
After a moment he said calmly,
“No immediate threat detected.”
“Good,” Clyde muttered.
Rani leaned forward again.
“Luke.”
He looked up.
“If she’s the Brigadier’s daughter, she’s probably trying to do the right thing.”
“That is an assumption.”
“It’s a reasonable one.”
Luke wiped his hands again, very carefully.
“UNIT secured alien technology from the house.”
“Yes.”
Luke said it almost conversationally.
“Technically speaking, I qualify as alien technology.”
Clyde stopped chewing.
Rani stared at him.
“You are not equipment.”
Luke tilted his head slightly.
“I was built by the Bane.”
“That doesn’t make you a device.”
“It makes me non-human.”
Clyde swallowed.
“Mate, if UNIT tries to catalogue you we’re stealing their filing cabinets.”
Luke reached for the vinegar again.
“I prefer to avoid the possibility entirely.”
Rani pushed his tray closer.
“You’re not hiding from UNIT.”
“I’m staying somewhere they won’t immediately check.”
“It’s your house.”
“It’s the first place they would look.”
“They’re not hunting you.”
“They might decide they have questions.”
“You could answer them.”
Luke gave her a very small, very Luke smile.
“I prefer when people don’t know where I am.”
Clyde shook his head.
“You’re basically Batman with better Wi-Fi.”
Luke opened his laptop bag slightly and pulled the computer halfway out.
“I’m running simulations.”
“From my sofa.”
“It’s a stable environment.”
Clyde looked proud.
“Told you.”
Rani stared at both of them.
“You two are impossible.”
Luke finally ate another chip.
“Efficient.”
She pointed one at him.
“You’re avoiding the house because it reminds you of your mum.”
Luke didn’t answer.
Outside, a bus splashed past in the rain.
Inside, the radio crackled softly.
Clyde cleared his throat.
“So… anyone want mushy peas?”
K-9 turned slightly toward Luke.
“Master Luke.”
“Yes?”
“Heart rate elevated, Master Luke.”
Luke paused.
“Thank you, K-9.”
Rani watched him for a long moment.
Then she nudged the tray again.
“Eat your dinner.”
Luke sighed quietly and picked up another chip.
“Yes, Rani.”
UNIT Headquarters hummed the way large organizations always did—quiet urgency layered over routine.
Screens glowed across the operations floor. Conversations moved in low, professional tones. Somewhere down the hall someone was arguing with logistics about satellite time.
Kate Stewart stood in the glass-walled briefing room overlooking it all.
A tablet rested on the table in front of her, filled with reports she had already read twice.
Mel leaned against the edge of the table, bright red hair impossible to miss even in UNIT’s carefully neutral lighting.
On the tablet screen a list of company names scrolled slowly.
Kate flicked to the next page.
“Three this week,” she said.
Mel peered over her shoulder.
“Four, technically. The drone manufacturing firm yesterday.”
Kate nodded once.
“Before our team even reached the site.”
Mel straightened.
“That one was a mess.”
“It would have been worse,” Kate said calmly. “They were integrating alien energy cells into civilian equipment.”
“Which is always a good sign,” Mel said dryly.
Kate tapped the screen.
The report opened to a schematic.
Someone had already annotated the diagram.
Efficiently.
Very efficiently.
Mel tilted her head.
“They disabled the power cascade.”
“Yes.”
“And the shielding loop.”
“Yes.”
Mel folded her arms.
“Well that’s tidy.”
Kate’s expression didn’t change.
“That’s what concerns me.”
Mel blinked.
“Most people would be grateful.”
“I am grateful.”
Kate closed the file.
“But I prefer to know who is interfering in my operations.”
Mel pushed herself upright.
“Interfering is a bit strong.”
Kate turned the tablet toward her.
“This individual infiltrated a corporate system we were still analyzing.”
Mel glanced down.
“Oh.”
“They identified the alien components.”
Mel nodded slowly.
“Oh.”
“They disabled the system safely.”
Mel looked impressed.
“Oh.”
Kate watched her.
“Yes.”
Mel looked back up.
“So… helpful.”
Kate clasped her hands loosely behind her back.
“Yes.”
“And you’re annoyed.”
“I am cautious.”
Mel tilted her head.
“That’s not the word your eyebrows are using.”
Kate allowed herself the smallest hint of a smile.
“Someone with this level of technical capability is operating independently inside extremely dangerous situations.”
“And solving them.”
“And solving them,” Kate agreed.
“Before UNIT teams arrive.”
Mel considered that.
“You’re worried they’ll get themselves killed.”
Kate walked toward the window overlooking the operations floor.
For a moment she simply watched the movement below.
A pair of analysts leaned over a console.
Two technicians rolled a containment unit past the glass.
Mel spoke gently behind her.
“You’re also worried you don’t control them.”
Kate turned slightly.
“UNIT operates under legal and operational constraints.”
“And your mystery helper does not.”
“Exactly.”
Mel wandered closer to the tablet again.
“Have we got anything on them at all?”
Kate tapped the screen again.
A new file opened.
Logs.
Network traces.
Short bursts of activity.
Mel squinted.
“They’re good.”
“Very.”
“No footprints.”
“Minimal.”
Mel whistled softly.
“Not a hobbyist.”
“No.”
“Professional?”
Kate considered the word.
“Not in the conventional sense.”
Mel looked back up.
“You think they’re someone who already knows alien tech.”
“Yes.”
“Someone trained.”
“Or someone self-taught with extraordinary aptitude.”
Mel glanced again at the reports.
“They flagged the alien components faster than our analysts.”
“Yes.”
Mel crossed her arms.
“Well.”
Kate waited.
“That’s either worrying or impressive.”
Kate didn’t answer immediately.
Instead she picked up the tablet again and opened another file.
A satellite image appeared.
The power plant incident from earlier that week.
Mel leaned closer.
“Let me guess.”
Kate zoomed the image.
A small section of infrastructure had been cleanly disabled.
Not destroyed.
Just… shut down.
“Before our team even deployed.”
Mel nodded slowly.
“That’s neat.”
Kate closed the file again.
“Yes.”
Mel watched her for a moment.
Then said casually,
“You want them.”
Kate looked up.
“I want them where I can see them.”
Mel smiled faintly.
“That’s the Brigadier talking.”
Kate allowed herself a quiet breath.
“My father preferred capable people on the inside.”
“And he had a knack for finding them.”
Kate nodded slightly.
“Yes.”
Mel studied her expression.
“You think this person might eventually cause a problem.”
“I think someone with that level of access and skill could accidentally become one.”
Mel tapped the tablet.
“Or they might already be saving your analysts a lot of time.”
Kate didn’t disagree.
She simply said,
“I would prefer they did it from a UNIT workstation.”
Mel grinned.
“You’re recruiting them.”
Kate folded her arms.
“If they are operating on Earth and interacting with alien technology, then they fall within UNIT’s operational concern.”
“That’s a very polite way of saying yes.”
Kate looked back toward the operations floor again.
The room hummed quietly.
Somewhere far below a lift opened.
Mel tilted her head.
“So what’s the plan?”
Kate’s voice remained calm.
“Find them.”
Mel’s smile widened.
“Oh, good.”
Kate glanced at her.
“I appreciate the assistance they’ve provided.”
“But?”
Kate tapped the tablet once more.
A line of code scrolled past the screen.
Someone else’s fingerprints inside her systems.
“But I prefer to know who is standing inside my operations.”
Mel laughed softly.
“Well.”
Kate looked at the screen again.
“Let’s find our ghost.”
The laundromat was open twenty-four hours.
At half past midnight it contained three washing machines, a vending machine that hummed like it had opinions, and Luke.
He sat at the small plastic table by the window with his laptop open. Rain ticked quietly against the glass. A washer thudded in a slow, steady rhythm somewhere behind him.
K-9 stood beside the chair, sensors moving lazily as he scanned the empty room.
Luke typed for a moment, then stopped.
“Status.”
K-9’s ears tilted slightly.
“No hostile presence detected. Lifeform approaching exterior entrance.”
Luke didn’t look up.
“Confirmed?”
“Confirmed.”
The door opened with a small bell chime.
The figure who stepped inside looked human in the vague way some aliens managed.
Too tall by a few centimeters. Shoulders slightly narrow. Skin the right color for human—just not quite the right shade.
They paused just inside the doorway, studying the room with careful attention.
Their eyes stopped on Luke.
Then on K-9.
Luke closed the laptop.
“Hello.”
The stranger approached cautiously.
“You are the one who answers requests.”
Luke tilted his head slightly.
“That depends on the request.”
The alien’s gaze flicked briefly to K-9 again.
“Your companion will not attack?”
“K-9?”
K-9’s voice came immediately.
“Negative. Hostility threshold not met.”
Luke gestured lightly to the chair opposite him.
“You can sit.”
The alien sat.
Up close the differences were clearer. The pupils moved slightly wrong. The breathing pattern was controlled in a way humans rarely bothered with.
Luke studied them in silence.
“Biology stable,” he said finally.
The alien blinked.
“You are scanning me.”
“Yes.”
“Your machine did the same.”
“K-9 is thorough.”
“Affirmative,” K-9 said.
The alien folded their hands together.
“My name would not translate easily.”
Luke nodded.
“That’s fine.”
“You are called Luke.”
“Yes.”
“You help people.”
“I help when it seems appropriate.”
The alien studied his face carefully.
“My property was taken.”
Luke waited.
“Humans found it.”
“Where?”
The alien reached slowly into their coat and produced a small rectangular device.
They placed it on the table.
Luke leaned forward.
The screen lit with a map of an industrial building on the edge of London.
A company name appeared in the corner.
Luke recognized it immediately.
He tapped the laptop open again and typed quickly.
A moment later schematics filled the screen.
“Defense contractor,” Luke said quietly.
“They are experimenting with it.”
Luke’s fingers moved across the keyboard.
“Where did you acquire the device originally?”
“It belongs to my vessel.”
Luke glanced up.
“And what does it do?”
The alien hesitated.
“Stabilizes gravitational distortions.”
Luke stopped typing.
“That would be extremely dangerous if used incorrectly.”
“Yes.”
“And humans currently have it.”
“Yes.”
Luke sat back.
K-9 spoke softly.
“Energy signature detected in file data. Device classification: high risk.”
Luke nodded once.
“Agreed.”
The alien watched him.
“You will retrieve it.”
Luke didn’t answer immediately.
Instead he zoomed the building plans.
Security routes appeared. Camera networks. Entry points.
“Why didn’t you ask UNIT?” Luke said.
The alien’s head tilted.
“UNIT?”
“Human organization dealing with alien activity.”
“We observed them.”
“And?”
“They would confiscate the device.”
Luke closed the file.
“Yes.”
“You would not.”
Luke rested his hands on the table.
“If the device is yours and you’re not threatening Earth, returning it seems reasonable.”
The alien relaxed slightly.
“You confirmed my intent.”
“Yes.”
K-9’s head turned toward the alien again.
“Probability of deception: extremely low.”
The alien looked faintly pleased.
Luke reached into his jacket pocket and pulled out a slim gold cylinder.
Under the laundromat lights the metal caught a warm reflection. At one end, the tiny emitter glowed soft pink when he thumbed the activation switch.
The alien’s eyes followed the movement.
“That is your tool.”
Luke rolled it once between his fingers.
“Not originally.”
K-9 spoke immediately.
“Object identified: Mistress Sarah Jane’s sonic device.”
Luke glanced down at him briefly.
“Yes.”
He pointed the lipstick at the building schematics on the screen, thinking.
“The door locks will be easy,” he said. “Corporate security tends to assume people behave predictably.”
The pink emitter flickered faintly as he turned it off again and slipped it back into his pocket.
“Which,” Luke added, standing, “they shouldn’t.”
The industrial park looked different after midnight.
During the day it was delivery vans, security gates, fluorescent offices pretending to be innovative. At night it was concrete, rain, and the quiet hum of machines that never actually stopped working.
Luke stood across the road studying the building.
Beside him, K-9’s sensors moved slowly, tracking the empty street.
“Camera coverage?” Luke asked quietly.
“Seven exterior cameras,” K-9 replied. “Two rotating. Five fixed.”
“Blind spots?”
“Three. Mapping now.”
Luke watched the pattern appear briefly on his laptop screen. Then he shut the computer and slid it back into his bag.
Across the road the facility’s main gate stood closed, a metal barrier with a badge reader mounted beside it.
Luke eyed it.
“Well that’s convenient.”
He crossed the street with K-9 rolling smoothly beside him. Rain ticked softly on the pavement.
K-9 stopped beside the gate.
“Electric current detected.”
Luke sighed.
“Of course there is.”
He reached into his jacket and pulled out the sonic lipstick. The slim gold cylinder caught the streetlight as he activated it. The emitter glowed soft pink.
“Object identified,” K-9 said immediately.
“Mistress Sarah Jane’s sonic device.”
Luke aimed it at the access panel beside the gate.
“Yes.”
The lipstick hummed.
Inside the panel a relay clicked. The keypad flickered.
The gate motor whirred quietly and slid open just wide enough to admit a delivery van.
Luke stepped through.
K-9 rolled in beside him.
Behind them the gate slid closed again with a quiet mechanical thud.
Luke slipped the lipstick back into his pocket.
“See?” he murmured.
K-9 tilted his head slightly.
“Entry successful.”
Luke glanced toward the building.
“Let’s go get someone’s property back.”
K-9 paused, scanning.
“Exterior cameras temporarily inactive.”
“Good.”
Luke moved toward the building.
The side entrance had a keypad lock and badge scanner.
Luke studied it for about three seconds.
Then he raised the lipstick again.
The pink emitter glowed.
The keypad lights flickered.
Inside the door a bolt slid open with a soft mechanical thunk.
Luke pushed the door gently.
“Corporate security,” he murmured. “Always optimistic.”
Inside, the corridor smelled faintly of disinfectant and overheated electronics. Fluorescent lights buzzed overhead.
K-9 rolled forward slightly.
“Two human life signs detected on upper level.”
“Night staff?”
“Likely.”
Luke slung his bag more securely over his shoulder.
“Where’s the device?”
K-9’s head turned left.
“Energy signature detected below. Laboratory level.”
Luke nodded once.
“Lead the way.”
They moved down the corridor quietly.
Luke walked with the easy caution of someone who had already mapped the building in his head.
K-9 stopped suddenly.
“Recommendation: avoid corridor three.”
Luke paused.
“Why?”
“Security patrol approaching.”
Luke sighed.
“Of course there is.”
He glanced around.
A service door sat slightly ajar nearby.
“Through there.”
They slipped inside just as a guard rounded the corner outside.
Luke held the door closed gently.
Footsteps passed.
A moment later K-9 said quietly,
“Area clear.”
Luke opened the door again.
“Thank you.”
They continued toward the stairs.
The lab level was colder.
Machines hummed behind glass walls. Screens glowed in the dim lighting.
Luke stopped outside one room.
Inside, two scientists in lab coats stood around a table.
On the table sat a small metal device connected to a lattice of wires.
Even from the hallway Luke could see the distortion rippling faintly around it.
Gravity bending in a slow, uneasy pulse.
Luke muttered,
“That’s not good.”
K-9’s sensors whirred softly.
“Device confirmed: gravitational stabilizer.”
“Improperly configured,” Luke added.
The scientists adjusted something on the console.
The distortion pulsed harder.
A metal tray slid slowly across the table by itself.
Luke grimaced.
“If that field collapses wrong it’ll take half the building with it.”
K-9 spoke calmly.
“Recommendation: intervention.”
Luke pulled the lipstick from his pocket again.
“Agreed.”
The pink emitter lit the hallway faintly.
Luke aimed it through the glass wall.
The lipstick hummed.
Inside the lab every screen flickered.
The machine powered down instantly.
Luke slipped the lab door open and stepped inside.
The two scientists barely had time to look up before the machine on the table sputtered and died.
The gravitational distortion collapsed with a soft pop.
Loose equipment clattered back onto the surface.
Luke moved straight to the table.
He unplugged the stabilizer carefully and turned it over in his hands.
“Improper containment,” he muttered.
One of the scientists stared at him.
“Who are you?”
Luke didn’t look up.
“Someone preventing a structural collapse.”
He slid the device into his bag.
Then he stepped to the nearby console.
K-9’s sensors swept the room.
“Security personnel approaching.”
“I know.”
Luke’s fingers moved quickly across the keyboard.
Lines of code flickered across the screen.
He rewrote the control system in seconds—isolating the alien power interface and locking the lab’s equipment out of it entirely.
The program finished with a quiet chime.
Luke erased the command history and stepped away.
Behind him the scientists were still staring.
“What did you just do?” one demanded.
Luke glanced back at the monitor.
“You were about three minutes from collapsing the local gravity field.”
He zipped the bag.
“You’re welcome.”
K-9 rolled toward the door.
“Security arrival imminent.”
Luke nodded and followed him out.
By the time security alarms started screaming ten seconds later, Luke and K-9 were already halfway across the parking lot.
Luke climbed the fence and dropped back onto the wet pavement outside.
K-9 landed beside him.
“Mission success,” K-9 said.
Luke adjusted the bag on his shoulder.
“Let’s return the property.”
He glanced once at the building as alarms echoed through the night.
Then he turned and walked into the rain.
UNIT Headquarters never really slept.
At three in the morning the operations floor was quieter, but the screens were still alive with shifting data and muted conversations. Somewhere down the hall a printer hummed steadily, like it had accepted its fate.
Kate Stewart stood in the analysis room with a tablet in one hand and a cup of coffee she had already forgotten to drink in the other.
On the main screen the lab security footage looped silently.
A door opened.
Two scientists turned.
Then the feed cut to static.
Kate watched it again.
Mel leaned against the console beside her.
“Well,” Mel said brightly, “that’s subtle.”
Kate didn’t answer.
The footage resumed.
The scientists were staring at the table.
Something was missing.
Mel folded her arms.
“They didn’t even see him.”
Kate tapped the screen.
“He knew exactly where the cameras were.”
Mel nodded.
“Professional.”
Kate didn’t look convinced.
“Not professional.”
Mel glanced sideways.
“What’s the distinction?”
Kate swiped the tablet.
A new display filled the screen.
System logs.
Mel leaned closer.
“Oh, this is interesting.”
Kate zoomed in.
The lab’s control program had been altered.
Not destroyed.
Rewritten.
Mel whistled softly.
“That’s tidy.”
“Yes.”
“And fast.”
“Yes.”
Mel tilted her head.
“You’re annoyed again.”
Kate set the tablet down.
“I’m impressed.”
“That’s not the word your shoulders are using.”
Kate ignored that.
She pointed to the screen.
“They shut down the alien device without damaging the containment system.”
Mel nodded.
“Which prevented a gravitational collapse.”
“Yes.”
“And saved the building.”
“Yes.”
Mel looked back at her.
“So… helpful.”
Kate clasped her hands behind her back.
“They also rewrote the lab’s entire interface architecture in under a minute.”
Mel raised an eyebrow.
“Which is… impressive.”
Kate nodded once.
“Very.”
Mel studied the code.
“Clean structure.”
“Yes.”
“Minimal commands.”
“Yes.”
“No wasted operations.”
Kate’s mouth tightened slightly.
Mel looked up.
“Oh.”
Kate didn’t answer.
Mel smiled slowly.
“You’ve seen this style before.”
Kate finally took a sip of the forgotten coffee.
“It’s distinctive.”
Mel tapped the screen again.
“They also erased their access logs.”
“Yes.”
“But not perfectly.”
Kate zoomed in again.
A tiny line of code remained.
A structural signature.
Mel squinted.
“That’s elegant.”
Kate nodded.
“Whoever this is understands alien technology.”
“And human security systems.”
“And programming.”
Mel glanced toward the frozen security footage again.
“They were physically inside the building.”
“Yes.”
“So your ghost hacker is now officially a ghost burglar.”
Kate turned off the video.
The room went quiet.
Mel watched her for a moment.
“You look pleased.”
Kate shook her head.
“I look concerned.”
“Because?”
Kate gestured toward the screen.
“Someone with this level of skill is operating independently inside extremely dangerous environments.”
“And solving the problem.”
“Yes.”
“Before UNIT arrives.”
Kate nodded.
“Yes.”
Mel leaned back against the console.
“So what are you going to do about them?”
Kate looked down at the code again.
Her voice was calm.
“Find them.”
Mel smiled.
“Oh good.”
Kate picked up the tablet again.
“This person understands alien systems better than most corporate researchers.”
“Clearly.”
“And they’re willing to intervene.”
“Also clearly.”
Kate tapped the tablet thoughtfully.
“My father used to say that if someone competent keeps appearing near your problems—”
Mel finished with a grin.
“—you should recruit them.”
Kate allowed herself the smallest smile.
“Yes.”
Mel glanced at the code again.
“Well, whoever they are…”
Kate waited.
“They’re clever.”
Kate turned toward the operations floor beyond the glass wall.
Analysts moved between consoles. Data streams flowed across the screens.
Her voice remained calm.
“But they’re not invisible.”
Mel tilted her head.
“You’ve got something.”
Kate held up the tablet.
“The code.”
Mel looked again.
“That’s not much.”
“It’s enough.”
Kate tapped the screen once.
“Everyone leaves patterns.”
Mel folded her arms.
“So you’re going to hunt the ghost.”
Kate’s eyes returned to the display.
“Yes.”
Mel grinned.
“Oh this is going to be fun.”
Kate didn’t smile.
“Let’s see how careful our mystery helper really is.”
The market street was loud in the comfortable way London markets always were.
Someone shouted about fresh strawberries. A busker was playing something energetic but slightly wrong. Bags rustled. People argued cheerfully about prices.
Donna Noble marched ahead through the crowd like a general conducting a campaign.
The Doctor followed two steps behind carrying three shopping bags.
“I still don’t understand why we needed another kettle,” he said.
Donna didn’t turn around.
“Because the old one whistles like a dying goat.”
“That’s character.”
“That’s irritating.”
They passed a row of takeaway shops, windows fogged with steam.
Donna glanced back.
“You wandered the universe for centuries and you can’t buy a decent kettle.”
“I bought a star once.”
“Did it whistle?”
“No.”
“Then it doesn’t count.”
The Doctor smiled faintly.
Then he stopped.
Donna walked three more steps before noticing.
She turned.
“What?”
The Doctor wasn’t looking at her.
He was looking through the window of a small chip shop.
Inside, a young man sat at a corner table.
Dark leather jacket. Laptop bag at his feet. A tray of chips in front of him that he clearly hadn’t been paying much attention to.
And beside the chair—
K-9.
The Doctor’s expression softened instantly.
Donna followed his gaze.
“Is that—”
“Yes,” the Doctor said quietly.
Donna squinted.
“That’s Sarah Jane’s lad.”
“Yes.”
Donna looked back at him.
“Well go on then!”
She shoved the shopping bags into his arms.
“What are you waiting for?”
The Doctor crossed the street.
The bell above the chip shop door chimed as he stepped inside.
Luke looked up automatically.
For a moment his brain clearly hadn’t caught up with what his eyes were seeing.
Then he stood so quickly the chair scraped loudly against the floor.
“Doctor—”
He crossed the room in two steps and pulled him into a hug.
It was sudden, tight, and completely uncalculated.
The Doctor laughed softly and returned it.
“Hello, Luke.”
Luke stepped back again, studying his face.
Something in his expression shifted.
“You changed.”
The Doctor tilted his head slightly.
“Yes.”
Luke frowned thoughtfully.
“You didn’t just regenerate.”
The Doctor blinked.
That had been fast.
Luke shrugged a little.
“My mum always said you carry your regenerations differently.”
The Doctor smiled.
“That sounds like her.”
Behind them Donna entered the shop carrying the bags again.
She looked between them.
“Right then.”
She pointed at Luke.
“You’re Sarah Jane’s boy.”
Luke nodded.
“Luke Smith.”
Donna grinned.
“Donna Noble.”
Luke smiled politely.
“Hello.”
Donna gestured at the floor.
“And that must be K-9.”
“Affirmative,” K-9 said.
Donna jumped slightly.
“Blimey.”
The Doctor pulled out the chair across from Luke and sat down.
“What have you been up to?”
Luke glanced down at the tray.
“Lunch.”
Donna snorted.
“He looks like he’s interrogating the chips.”
Luke picked one up and ate it.
The Doctor watched him for a moment.
“You’ve been busy.”
Luke shrugged slightly.
“Helping people.”
The Doctor smiled faintly.
“Yes.”
Luke met the Doctor’s eyes.
“Someone has to be,” he said.
Donna leaned forward across the table, squinting at him.
“Hang on.”
Luke glanced at her.
“You’re that bloke Kate’s been complaining about.”
Luke froze.
The Doctor closed his eyes briefly.
Donna pointed at him.
“The hacker! The one shutting down dodgy alien tech before UNIT gets there!”
Luke stood.
The chair scraped sharply across the floor.
His hand was already reaching for the laptop bag.
“Right,” he said quickly. “Lovely seeing you.”
“Luke—”
“I should go.”
K-9 immediately rolled into position beside him.
“Departure acknowledged,” K-9 said.
Donna blinked.
“Oi! What did I say?”
Luke slung the bag over his shoulder.
“I prefer not to be on UNIT’s radar.”
The Doctor stood as well.
“Luke.”
Luke didn’t meet his eyes.
“Kate Stewart is actively looking for someone matching my operational profile.”
Donna folded her arms.
“Well that sounds very official.”
Luke adjusted the strap on the bag.
“I operate more effectively when organizations like UNIT are not involved.”
The Doctor tilted his head.
“Sit.”
Luke blinked.
“What?”
“Sit down.”
Luke hesitated.
K-9 spoke.
“Recommendation: remaining present does not significantly increase threat probability.”
Luke looked down at him.
“You’re not helping.”
“Correction: assisting.”
The Doctor waited.
Luke sighed quietly.
Then he sat back down.
Donna grinned.
“There we go.”
The Doctor sat again.
“Luke,” he said gently, “why are you so determined to stay off UNIT’s radar?”
Luke hesitated.
Then said simply,
“They cleared out Bannerman Road.”
The Doctor’s expression stilled.
Luke kept his voice calm.
“They catalogued everything alien in the house.”
Donna winced.
“Oh.”
“Mr. Smith,” Luke continued. “Anything they thought counted as technology. They only didn't take K-9 because he was with me.”
The Doctor didn’t interrupt.
“They even took my mum’s TARDIS key.”
The Doctor went very still.
“They confiscated Sarah Jane Smith’s TARDIS key.”
“Yes.”
A small silence settled over the table.
Donna muttered under her breath.
“Oh, that’s annoying.”
The Doctor reached slowly into his coat pocket.
His expression had gone very calm.
Donna recognized that look immediately.
Doctor annoyed.
He placed a small brass key on the table.
Luke stared at it.
“You’re giving me a TARDIS key.”
“Yes.”
“Why?”
The Doctor shrugged slightly.
“The TARDIS is parked in Donna’s back garden.”
Donna raised a hand.
“Hello.”
Luke blinked.
“You’re… parked.”
“Yes.”
“You don’t travel anymore.”
“Not the way I used to.”
Luke studied him carefully.
Then looked back down at the key.
“You’re giving me access to a TARDIS.”
“Yes.”
“That seems irresponsible.”
Donna laughed.
“You’ve met him, right?”
The Doctor leaned forward slightly.
“You help people.”
Luke didn’t deny it.
“You’re sleeping on Clyde’s couch.”
Luke didn’t argue that either.
“You need somewhere safe,” the Doctor said.
Luke’s eyes flicked up.
“And the TARDIS likes you.”
“That’s not a reliable metric.”
“Oh, I think it is.”
K-9 spoke calmly from beside the chair.
“Assessment: probability of TARDIS welcoming Master Luke exceeds ninety-seven percent.”
Luke looked down at him.
“You’re not helping.”
“Correction: assisting.”
Luke picked up the key.
It sat in his palm for a moment.
Heavy.
Real.
The Doctor watched him quietly.
“You’ll always have somewhere to go,” he said.
Luke didn’t answer.
But he didn’t give the key back.
Donna Noble’s back garden had never been particularly quiet.
The neighbors’ cat used it as a shortcut. The washing line creaked whenever the wind changed direction. Somewhere two streets over someone’s dog barked at absolutely nothing with impressive dedication.
And in the far corner, behind the shed and a leaning fence panel, a blue police box stood under the garden light.
Luke paused at the back gate.
K-9 rolled up beside him.
“Location confirmed,” K-9 said. “TARDIS present.”
Luke studied the police box.
The Doctor had said it casually enough over chips.
It’s parked in Donna’s garden.
Luke reached into his pocket and pulled out the brass key. He turned it in his fingers for a moment.
“Statistically speaking,” he said quietly, “this could still be a joke.”
K-9’s head unit tilted.
“Probability of Doctor engaging in humor: extremely high.”
“Thank you, K-9.”
They crossed the grass.
The TARDIS stood quietly in the corner, the lamp glowing faintly above the doors.
Luke stopped in front of it.
For a moment he didn’t move.
He hadn’t been inside the TARDIS since he was a child.
Different console room then.
Different Doctor.
Same impossible machine.
He lifted the key toward the lock.
The door clicked open.
Luke blinked.
He hadn’t touched it.
K-9 rolled slightly forward.
“Access granted.”
Luke narrowed his eyes at the door.
“…Right.”
The doors opened a few inches wider.
Warm light spilled out across the garden grass.
Luke stepped inside.
The doors closed gently behind him.
The console room stretched around him—vast, bright, humming softly with that familiar impossible sound.
Luke stood very still.
K-9 rolled onto the metal floor beside him.
“Environmental systems stable,” K-9 reported.
Luke looked slowly around the room.
“…Still bigger.”
The engines hummed faintly, almost like an answer.
Luke slipped the key back into his pocket.
“Well,” he said quietly.
“This is new.”
A corridor light blinked on.
Then another.
Then another.
One after the other.
A path.
Luke watched it for a moment.
“You’re helping.”
Another light flicked on farther down the corridor.
K-9 scanned.
“Guidance pattern detected.”
Luke sighed.
“Fine.”
He followed the lights.
The corridor curved gently through the ship. The air smelled faintly of something warm and familiar—metal, tea, time.
The lights led him to a door.
It opened before he touched it.
Inside was a room.
Not large.
But comfortable.
Books on a shelf. A desk with scattered notebooks. A jacket over the back of a chair.
And on the bed—
Owlie.
Luke stopped in the doorway.
K-9 rolled forward slightly.
“Object identified: Mistress Sarah Jane’s plush companion.”
Luke exhaled slowly.
“…Yes.”
The room felt warm.
Not preserved.
Not staged.
Just… remembered.
Luke stepped inside.
He set the laptop bag beside the desk.
Picked up Owlie automatically.
Turned it over in his hands.
“…You kept it.”
The TARDIS hummed softly somewhere deep in its structure.
A knock sounded on the doorframe.
Luke looked up.
The Doctor leaned into the room, one shoulder against the door.
“Hello.”
Luke blinked.
“I thought you said you didn’t travel anymore.”
“I don’t.”
The Doctor smiled faintly.
“But I do live here.”
Luke glanced toward the corridor.
“You followed me.”
The Doctor shrugged.
“She tends to announce new guests.”
Luke looked down at Owlie again.
“…That’s fair.”
The Doctor nodded toward the hall.
“There’s dinner in the kitchen.”
Luke frowned slightly.
“You have a kitchen.”
“Yes.”
“Inside the TARDIS.”
“Yes.”
Luke considered that.
“That seems unnecessary.”
The Doctor grinned.
“You haven’t met Donna in cooking mode.”
Luke placed Owlie carefully back on the bed.
Then picked up his bag again.
“Right.”
He stepped toward the door.
K-9 rolled out ahead of him.
“Food preparation detected,” K-9 said. “Probability of edible outcome: high.”
Luke paused.
“You’re optimistic.”
“Assessment based on scent analysis.”
The Doctor gestured down the corridor.
“Come on then.”
Luke followed.
Behind them the room lights dimmed slightly.
The back gate creaked open.
Rani slipped through first, phone in one hand, bag slung over her shoulder.
Clyde followed, glancing around like he expected Donna Noble herself to appear and start asking questions.
“This is still weird,” he muttered.
“You said that already,” Rani replied.
“Yeah, well it’s still true.”
He pointed across the garden.
The blue police box stood quietly beside the shed.
“That thing used to show up when the Doctor was around.”
Rani nodded.
“Luke said it’s parked.”
“Parked.”
“Yes.”
“You can’t park a time machine.”
Rani shrugged.
“Apparently you can.”
K-9’s head appeared around the corner of the police box.
“Greetings.”
Clyde jumped.
“Blimey!”
Rani smiled.
“Hello, K-9.”
“Master Luke is present.”
The TARDIS door opened.
Luke stepped out onto the grass, laptop tucked under one arm.
He looked marginally less scruffy than usual.
Still scruffy.
“You found it,” he said.
Clyde stared at the police box.
“You’re living in it.”
Luke considered the wording.
“Yes.”
Clyde rubbed his face.
“You’re living in a time machine in Donna Noble’s garden.”
“Yes.”
“That feels illegal.”
“It probably is.”
Rani waved her phone.
“Luke.”
He focused immediately.
“What did you find?”
She brought up a set of photos.
Industrial warehouse.
Night activity.
Strange equipment.
“I’ve been tracking shipments through a logistics company connected to that lab you broke into,” she said.
Luke nodded.
“Reasonable.”
“They moved equipment two nights ago.”
“Where?”
Rani zoomed in on a satellite image.
Luke studied it.
“Industrial storage facility,” he said.
“Yeah,” Clyde added.
“But that’s not the weird part.”
Luke glanced up.
Clyde tapped the screen.
“These.”
A security camera still showed several armored figures.
Rounded helmets.
Bulky armor.
Luke froze.
“…Oh.”
Rani frowned.
“You know what that is?”
Clyde folded his arms.
“Sontarans.”
Luke exhaled slowly.
“That’s unfortunate.”
Rani blinked.
“Unfortunate?”
“They’re a militaristic clone species with an expansionist philosophy.”
Clyde nodded.
“Also very shooty.”
Rani looked between them.
“So that’s bad.”
“Yes,” Luke said.
K-9’s sensors whirred.
“Species identified: Sontaran.”
Luke ran a hand through his hair.
“Right.”
Clyde leaned against the fence.
“UNIT?”
Luke shook his head immediately.
“No.”
Rani nodded.
“They’ll show up with soldiers.”
“Yes.”
“And the Doctor?”
Luke glanced toward the house.
Lights glowed in the kitchen window.
Donna’s silhouette moved past briefly.
“No.”
Clyde raised an eyebrow.
“Why not?”
Luke closed the laptop.
“He’s retired.”
Rani frowned slightly.
“Since when does that stop him?”
“It shouldn’t need to.”
Luke looked back at the photos.
“Sontaran operations on Earth tend to follow predictable patterns.”
Clyde grinned.
“Meaning?”
Luke started toward the TARDIS doors.
“Meaning we can stop them.”
Rani followed.
“How?”
Luke pushed the door open.
The console room lights brightened as they entered.
“First,” he said, moving toward the console,
“we find out what they’re doing here.”
Clyde stepped inside and looked around.
“Still bigger.”
“Yes,” Luke said absently.
He began typing rapidly at the console.
K-9 rolled up beside him.
“Shall we notify the Doctor?”
Luke didn’t look up.
“No.”
Rani folded her arms.
“You’re sure?”
Luke glanced toward the corridor leading deeper into the ship.
Somewhere down there, dinner was probably still sitting in the kitchen.
“We’ll handle it,” he said.
Clyde grinned.
“Like old times.”
Luke’s fingers paused on the console for half a second.
“…Yes.”
Then he started the scan.
And deep inside the TARDIS, the engines hummed quietly—almost as if listening.
The console hummed softly under Luke’s hands.
Light from the central column washed the room in shifting amber and blue. Outside the police box, Donna’s garden was quiet again—the washing line creaking faintly in the wind—but inside the TARDIS the air felt charged with attention.
Luke typed.
Lines of data spilled across the monitor panels surrounding the console.
Coordinates. Thermal signatures. Structural schematics pulled from orbital scans the TARDIS clearly considered trivial to access.
Rani leaned forward slightly.
“You’re pulling satellite feeds.”
“Yes.”
Clyde wandered a slow circle around the console.
“That’s a lot of screens.”
Luke didn’t look up.
“Efficiency.”
K-9 rolled closer to the display bank.
“Energy fluctuations detected within target structure.”
Luke nodded once.
“Show me.”
The main screen shifted.
The warehouse appeared in cross-section—walls ghosted transparent as the scan penetrated concrete and steel.
Inside, movement.
Large shapes.
Armored.
Clyde leaned closer.
“Well that’s unpleasantly familiar.”
Three Sontarans moved across the floor, hauling equipment from a crate the size of a delivery pallet. Another figure—larger, marked with heavier armor—stood overseeing the operation.
Rani folded her arms.
“How many?”
Luke zoomed the scan.
Heat signatures blinked into clarity.
“Five soldiers,” he said quietly. “And one commander.”
Clyde scratched his head.
“Right. That’s… six Sontarans.”
Rani glanced between them.
“Is that a lot?”
“Yes,” Clyde said.
“No,” Luke said.
They looked at him.
Luke leaned closer to the display.
“They’re not positioned for combat.”
Clyde frowned.
“They’re Sontarans. They’re always positioned for combat.”
Luke ignored him.
“Look.”
He tapped a key.
The scan shifted deeper into the building.
A cleared circle had been carved out of the warehouse floor. Metal plates had been laid across the concrete.
In the center of the circle stood a machine.
It rose nearly three meters high, built from dark metal struts and rotating rings that turned slowly around a central column. Energy flickered between them in thin blue arcs.
Even through the scan the distortion was obvious.
Gravity bending.
Time wobbling.
K-9’s sensors whirred sharply.
“Device classification uncertain. Energy signature inconsistent with terrestrial technology.”
Luke exhaled slowly.
“…Oh.”
Clyde looked at him.
“Oh what?”
Luke zoomed the display again.
The rotating rings came into clearer focus.
Alignment markers.
Temporal calibration nodes.
Fleet coordinate brackets.
Recognition landed behind Luke’s eyes.
“They’re not here to fight,” he said.
Rani tilted her head.
“Then what are they doing?”
Luke leaned back slightly.
“They’re building something.”
Clyde gestured at the screen.
“Yes. That enormous thing.”
Luke nodded once.
“It’s a beacon.”
Silence settled over the console room.
Clyde blinked.
“…A what?”
Luke pointed at the central column.
“Sontaran deployment beacon.”
Rani frowned.
“Which means?”
Luke’s voice stayed calm.
“They’re establishing a fleet drop point.”
Clyde stared at the screen.
“Fleet.”
“Yes.”
Rani looked from the display to Luke.
“And how many ships does a Sontaran fleet usually have?”
Luke didn’t answer immediately.
Clyde rubbed his face.
“That’s never a good pause.”
Luke zoomed further into the machine.
Power cells glowed at the base. Signal rings rotated slowly above them.
“It’s incomplete,” he said.
Clyde leaned closer.
“You sure?”
“Yes.”
“How do you know?”
Luke pointed again.
“They haven’t calibrated the synchronizer.”
Rani squinted at the screen.
“You can tell that from a scan?”
“Yes.”
Clyde shook his head slowly.
“Your mum would’ve loved this.”
Luke didn’t respond.
His fingers moved across the console again. The image rotated, isolating the machine’s internal structure.
K-9 spoke quietly beside him.
“Energy levels increasing within device core.”
Luke nodded.
“They’re testing it.”
Rani’s eyes widened slightly.
“So they could turn it on tonight?”
“Yes.”
Clyde pointed toward the warehouse image.
“Well that seems like something we should prevent.”
Luke studied the structure for several seconds more.
Then he leaned back.
“We will.”
Clyde folded his arms.
“Good.”
Pause.
“How?”
Luke zoomed in on the machine again. The central interface panel flashed briefly as a Sontaran technician adjusted something.
Luke watched the movement.
Then smiled faintly.
“Oh.”
Rani recognized that tone immediately.
“What?”
Luke tapped the screen.
“They made a mistake.”
Clyde leaned closer.
“Sontarans don’t make mistakes.”
“They do when they assume the battlefield will behave.”
Rani frowned.
“Meaning?”
Luke straightened.
“They designed the beacon for stable coordinates.”
Clyde blinked.
“…Which is bad?”
Luke shut down the scan window.
“No.”
He looked up at them.
“It’s useful.”
Rani tilted her head.
“You’ve already figured out how to stop it.”
Luke shrugged slightly.
“Yes.”
Clyde stared.
“You’ve been looking at that thing for thirty seconds.”
“That was sufficient.”
Rani gestured toward the screen.
“So what do we do?”
Luke reached for his jacket.
“We change what it says.”
Clyde frowned.
“What does that mean?”
Luke headed toward the TARDIS doors.
“It means,” he said calmly, “the Sontaran fleet is about to receive very confusing coordinates.”
K-9 rolled after him.
“Clarification requested.”
Luke glanced back over his shoulder.
“We’re going to make Earth look like a terrible place to start a war.”
Clyde grinned slowly.
“Oh.”
Rani grabbed her bag.
“…That actually sounds like a plan.”
Luke pushed open the TARDIS doors.
Outside, the garden was still quiet.
But somewhere across London, a warehouse full of Sontarans continued building a machine that was about to stop working.
Luke stepped out onto the grass.
“Come on,” he said. “Let’s go break their beacon.”
The industrial park was nearly silent.
Rain misted through the orange glow of the streetlights and settled on the rows of quiet warehouses. Delivery trucks sat motionless behind chain gates. Somewhere far away a train rattled across tracks.
Luke studied the building across the road.
K-9 rolled to a stop beside him, sensors sweeping the structure in slow arcs.
“Patrol pattern unchanged,” K-9 reported.
Luke nodded once.
“Good.”
Rani hugged her jacket a little tighter against the cold.
“You’re very calm about this.”
Luke didn’t look away from the building.
“They’re following the pattern the scan predicted.”
Clyde shoved his hands in his pockets and squinted at the warehouse.
“Still feels weird walking toward a building full of Sontarans on purpose.”
“That’s because it is weird,” Rani said.
Luke closed the laptop and slipped it back into his bag.
“We only need to reach the beacon platform.”
Clyde nodded toward the side entrance.
“And that door?”
Luke pulled the sonic lipstick from his pocket. The gold casing glinted briefly under the streetlight as the pink emitter came alive.
“Yes.”
The lock clicked open almost immediately.
Clyde shook his head.
“One day that thing’s going to refuse to cooperate.”
Luke pushed the door open.
“It hasn’t yet.”
Inside, the corridor smelled faintly of oil and disinfectant. Fluorescent lights hummed overhead.
Luke paused at the end of the hall and glanced toward the warehouse floor.
Then he stepped slightly aside.
Clyde leaned forward and looked past him.
Rows of cargo crates stretched across the warehouse. Between them, heavy armored figures moved methodically through the aisles. At the far end of the floor the beacon towered over the operation—rings turning slowly, blue energy flickering between them while Sontaran engineers worked around the base.
Clyde exhaled quietly.
“…Still hate them.”
Luke watched the nearest patrol pass across the aisle exactly when the scan had predicted.
“Good,” he murmured.
Clyde blinked.
“How is that good?”
“It means the timing hasn’t changed.”
Luke waited two seconds.
The Sontaran disappeared behind a stack of cargo containers.
Luke stepped onto the warehouse floor.
“Come on.”
K-9 rolled after him.
“Stealth approach engaged.”
Clyde followed, muttering under his breath.
“Right. Sneaking past Sontarans. Perfectly normal evening.”
Ahead of them, the beacon’s rings rotated slowly.
Luke’s eyes stayed fixed on it.
“Almost there.”
Luke moved first.
The nearest Sontaran patrol had just turned down the next aisle exactly when the scan predicted. Heavy boots faded slowly across the concrete floor.
Luke slipped from the doorway into the shadow between two stacks of cargo crates.
K-9 rolled silently after him.
Clyde followed, pausing long enough to glance back down the corridor before ducking into cover.
For a moment they stood still.
The warehouse stretched around them—rows of pallets, metal shelving, forklifts parked like sleeping animals. Overhead lights buzzed softly.
Across the open floor the beacon rotated slowly. Blue energy flickered between its rings.
Clyde leaned slightly around the edge of the crate and looked again.
“…That thing is enormous.”
Luke watched the patrol route instead of the machine.
“They’re building it in stages.”
“That doesn’t make it smaller.”
K-9’s sensors turned.
“Sontaran patrol approaching adjacent aisle.”
Luke nodded once.
“Down.”
They crouched as a Sontaran soldier marched past the far end of the crate row. Armor plates clanked softly with each step.
The soldier paused briefly, scanning the warehouse.
Clyde held his breath.
Then the Sontaran continued down the next aisle.
K-9 spoke quietly.
“Patrol cycle continuing.”
Luke rose.
“Move.”
They crossed the gap between crate stacks quickly.
Clyde kept glancing toward the beacon. Sontaran engineers moved around its base, adjusting equipment mounted on the platform.
One of them slammed a tool into place with a metallic crack.
Clyde winced.
“Subtle.”
Luke studied the movement of the engineers for a moment.
“They’re focused on the core assembly.”
“Good for us?”
“Yes.”
They moved deeper between the stacks.
Halfway across the warehouse Clyde froze.
Two human security guards stood near a rolling cart at the end of the aisle. One of them was scrolling through something on a phone. The other was staring out across the floor toward the Sontarans.
Neither looked particularly happy about being there.
Clyde leaned back toward Luke.
“Human complication.”
Luke followed his gaze.
The guards were standing directly between them and the next row of crates.
He considered the layout for about two seconds.
Then looked at Clyde.
“Can you distract them?”
Clyde grinned slowly.
“Oh absolutely.”
Luke raised an eyebrow.
“Quietly.”
“Define quietly.”
Luke didn’t answer.
Clyde slipped away down a side aisle before Luke could change his mind.
K-9 watched him go.
“Probability of Clyde causing minor disruption: high.”
Luke sighed faintly.
“Yes.”
Across the warehouse Clyde reached a forklift parked beside a pallet of shipping crates. He glanced once toward the guards, then pulled a loose strap from one of the pallets and hooked it around the forklift’s lift lever.
A moment later the machine lurched slightly.
The pallet shifted.
A tower of plastic containers slid off the stack and crashed onto the concrete floor.
The sound echoed across the warehouse.
Both security guards jumped.
“What the—?”
They rushed toward the spill.
Clyde stepped neatly out of sight behind the forklift.
Across the aisle Luke watched the guards disappear around the corner.
Then he nodded once.
“Efficient.”
K-9 rolled forward.
“Path now clear.”
Luke slipped between the crate stacks again.
The beacon platform loomed closer now. The rings turned slowly, humming with energy.
At the center of the platform the Sontaran commander stood with his hands clasped behind his back, watching the technicians work.
Clyde reappeared beside Luke a moment later.
“Minor disruption achieved.”
Luke glanced at him.
“Well done.”
Clyde looked genuinely pleased.
They both turned toward the platform.
Only one open stretch of floor remained between them and the beacon.
Luke studied the patrol timing again.
Then spoke quietly.
“Next pass gives us fifteen seconds.”
Clyde flexed his hands.
“Plenty.”
The Sontaran patrol turned the far corner.
Luke stepped out from the crates.
“Now.”
Rani stood on the pavement across from the industrial park entrance.
From here the warehouse looked completely ordinary. Concrete walls. Security lighting. A row of delivery trucks sitting quietly behind the fence.
Nothing about it suggested an alien military operation was unfolding inside.
Which, Rani thought, was exactly why it worked.
She checked the time on her phone.
Luke and Clyde had been inside for three minutes.
That was long enough for them to reach the main floor.
Not long enough for the Sontarans to notice anything had gone wrong.
Yet.
K-9’s voice crackled quietly through the small comm unit Luke had handed her before they split up.
“Exterior channel clear.”
“Good,” Rani murmured.
She took a slow breath and opened the emergency services page on her phone.
A burner SIM card sat inside the device. One of Clyde’s suggestions. He’d handed it to her earlier with the casual air of someone who had learned strange skills from long experience.
“Just in case,” he’d said.
Rani stared at the number for a moment.
Then she pressed call.
It rang once.
A calm voice answered immediately.
“Emergency. Which service do you require?”
Rani shifted slightly so the warehouse filled her line of sight.
“Fire brigade,” she said.
A pause.
“Connecting you now.”
The line clicked.
A different voice came on.
“Fire control. What’s the address of the emergency?”
Rani read the warehouse number off the security sign beside the gate.
“There’s a chemical leak at an industrial storage facility,” she said quickly. “Strong fumes coming from the loading area. People inside the building.”
“Have you seen anyone injured?”
“No, but the smell’s getting worse.”
That wasn’t technically a lie.
Alien technology misused by defense contractors probably smelled terrible.
The dispatcher’s voice sharpened slightly.
“Understood. Units are being dispatched now. Please keep your distance from the building.”
“I already have,” Rani said.
“Stay where you are in case responders need additional information.”
“Of course.”
She ended the call before the dispatcher could ask anything else.
For a moment she simply stood there listening to the quiet street.
Then she slipped the phone back into her pocket.
“Right,” she muttered.
Across the road the warehouse lights glowed steadily.
Nothing looked different.
But inside, Luke was somewhere near the center of the building trying to sabotage a Sontaran deployment beacon.
Rani folded her arms.
“Let’s see how fast London responds to a chemical emergency.”
She checked the street again.
Still quiet.
But emergency dispatch systems worked quickly in this part of the city.
Sooner or later—
Faintly, somewhere far away, a siren began to rise.
Rani smiled to herself.
“Perfect timing.”
Luke crossed the open stretch of floor in three silent strides.
Clyde kept pace beside him, eyes flicking constantly between the patrol route and the Sontaran engineers clustered around the beacon platform.
The machine loomed larger with every step.
Up close the energy field was stronger. The air hummed faintly, like a power line vibrating somewhere deep in the walls.
K-9 rolled onto the edge of the platform behind them.
“Energy output increasing,” he reported quietly.
Luke nodded.
“Testing cycle.”
Two Sontaran technicians stood with their backs to the floor, both focused on a control console mounted near the base of the beacon. One of them barked something sharp in Sontaran. The other responded without looking up.
Neither had turned around.
Yet.
Luke stepped onto the metal plates surrounding the device.
The rings above them rotated slowly, each one sliding past the others with a low mechanical whirr.
Clyde craned his neck upward.
“Right,” he whispered. “That’s intimidating.”
Luke ignored the rings.
He was studying the base of the structure.
There.
A rectangular access seam just below the central column.
He pulled the sonic lipstick from his jacket.
The pink emitter glowed softly as he knelt beside the panel.
K-9 moved slightly closer to the edge of the platform, sensors rotating.
“Patrol approaching west aisle.”
Luke placed the emitter against the seam.
The lipstick hummed.
The panel slid open with a quiet metallic click.
Inside, alien circuitry glowed faintly.
Layered plates of Sontaran engineering surrounded a compact control core threaded with thin cables and crystalline connectors.
Clyde crouched beside him.
“…Please tell me you understand that.”
“Yes.”
“That was not reassuring.”
Luke pulled the laptop from his bag and connected a small cable to the interface port.
The screen lit immediately as the system handshake began.
Lines of alien code scrolled rapidly across the display.
Behind them one of the Sontaran engineers slammed a tool against the beacon housing with a loud metallic crack.
Neither technician turned around.
Luke began typing.
K-9 spoke quietly.
“External audio detection: emergency vehicle sirens approaching area.”
Luke didn’t look up.
“Good.”
Clyde glanced toward the warehouse doors.
“That would be Rani.”
“Yes.”
On the laptop screen the synchronization architecture unfolded—coordinate matrices, fleet alignment parameters, temporal calibration loops.
Luke navigated the structure in seconds.
“There you are,” he murmured.
Clyde leaned closer.
“What am I looking at?”
“The synchronizer.”
“That’s the part that calls the fleet.”
“Yes.”
Luke’s fingers moved quickly over the keyboard.
Clyde watched the code change.
“You’re rewriting it.”
“Yes.”
“What happens when they turn it on?”
Luke didn’t pause.
“The signal will loop.”
Clyde blinked.
“…Loop.”
“The fleet receives corrupted coordinates.”
“That sounds bad.”
“For them.”
Behind them the beacon’s rings began rotating slightly faster. Energy crackled between the metal arcs.
One of the technicians barked something in Sontaran again. The other nodded sharply.
K-9’s sensors turned toward the aisle.
“Sontaran commander approaching platform.”
Luke finished the final line of code.
The system accepted the rewrite with a soft electronic chime.
He closed the laptop.
“Done.”
Clyde exhaled slowly.
“That was quick.”
Luke sealed the access panel again with the sonic lipstick.
The seam slid shut.
Across the platform the heavy footsteps of command armor echoed against the metal plates.
Luke stood.
And turned just as the Sontaran commander stepped onto the platform and saw them.
Heavy boots struck the metal plates.
The Sontaran commander stopped three meters away, broad shoulders filling the space between the rotating rings of the beacon. Command markings glinted across the armor collar.
For a moment the only sound was the low hum of the machine.
The commander’s helmet turned slowly toward them.
Then the voice came—harsh, amplified through the armor.
“Human infiltrators.”
The two Sontaran technicians spun around instantly, weapons coming up.
Clyde raised both hands halfway.
“Right. Well. That escalated quickly.”
Luke didn’t move.
The commander took two deliberate steps forward, studying them.
“You have entered a Sontaran military installation.”
Luke glanced briefly toward the beacon’s rings, which were still accelerating.
“Yes,” he said calmly.
The commander’s helmet tilted slightly.
“You display unusual composure for a civilian organism.”
Clyde nodded toward Luke.
“He does that.”
Luke ignored him.
Behind the commander the technicians returned to the control console. One of them struck a sequence of commands.
The beacon’s rings spun faster. Energy arced between them in bright blue flashes.
The Sontaran commander folded his arms behind his back.
“Your species demonstrates persistent curiosity.”
Luke watched the machine for another moment.
“You’re preparing a deployment beacon.”
The commander’s posture shifted slightly.
“Correct.”
“Fleet staging signal,” Luke continued.
“Yes.”
Clyde leaned slightly toward Luke.
“Just to confirm, that’s still bad.”
“Yes,” Luke said quietly.
The commander studied him again.
“You understand the device.”
Luke nodded.
“Yes.”
“That is… unexpected.”
Luke shrugged faintly.
“You built the synchronizer incorrectly.”
Silence fell across the platform.
One of the technicians stopped typing.
The commander stepped closer.
“There is no error in Sontaran engineering.”
Luke tilted his head.
“There was.”
Clyde muttered under his breath.
“Oh this should go well.”
The commander’s armor hummed softly as he moved.
“You presume to lecture a Sontaran commander about military technology.”
Luke glanced toward the console.
“They’re about to activate it.”
“Yes.”
The commander’s voice sharpened with pride.
“The Sontaran fleet will soon receive this world’s coordinates.”
Luke nodded once.
“Yes.”
Then he looked back at the commander.
“That won’t work.”
The commander froze.
The technicians struck the final command.
The beacon roared to life.
The rotating rings snapped into perfect alignment. Energy surged up the central column in a blinding shaft of light.
The machine emitted a deep resonant pulse that rolled through the warehouse.
Clyde squinted upward.
“That looks like transmitting.”
Luke watched the control panel.
“Yes.”
The commander stood perfectly still, helmet tilted slightly as he listened to the data feed in his armor systems.
Several seconds passed.
Then—
A harsh burst of static crackled from the console.
One of the technicians slammed a fist against the interface.
“SIGNAL INSTABILITY,” the armor translated.
The commander turned slowly toward the display.
Another burst of static.
Coordinates scrolled across the screen.
Then looped.
Then looped again.
The technician barked something sharp.
The commander’s voice hardened.
“Report.”
The technician turned from the console.
“DEPLOYMENT COORDINATES UNSTABLE.”
Luke folded his arms.
“Yes.”
The commander stared at him.
“You interfered.”
Luke nodded.
“I corrected your synchronizer.”
“That device was functioning perfectly.”
Luke shook his head slightly.
“It assumed stable temporal coordinates.”
The commander stepped forward again, looming over him.
“Explain.”
Luke gestured lightly toward the machine.
“Earth doesn’t have those.”
The technician struck the console again.
The same data loop returned.
Coordinates.
Error.
Loop.
Error.
The commander’s armor emitted a low electronic growl.
“Fleet command will reject this signal.”
“Yes.”
“Deployment cannot proceed.”
“Yes.”
Clyde looked between them.
“So… we win?”
Luke nodded slightly.
“Yes.”
The commander studied him for a long moment.
Then spoke slowly.
“Human strategist.”
Luke said nothing.
“You have prevented a Sontaran deployment.”
Luke shrugged faintly.
“No.”
The commander’s helmet tilted.
“No?”
Luke nodded toward the beacon.
“I made Earth look like a terrible place to start a war.”
Another burst of static rattled through the console.
Behind the commander, one of the technicians spoke urgently.
The armor translated automatically.
“EMERGENCY VEHICLES APPROACHING STRUCTURE.”
Faintly now, sirens echoed through the night outside.
Clyde grinned.
“Oh that’ll be Rani.”
The commander looked once more at the corrupted display.
Then back at Luke.
“Your interference is noted.”
Luke inclined his head slightly.
“Thank you.”
The commander turned sharply toward his soldiers.
“ABORT OPERATION.”
Weapons lowered instantly.
Technicians began shutting down the beacon. The rings slowed. Energy faded.
The Sontaran commander looked back at Luke one final time.
“This engagement will be remembered.”
Luke met his gaze calmly.
“I assumed so.”
The commander marched off the platform.
Moments later the Sontarans were already dismantling their equipment.
Clyde watched them go.
“…Did we just talk a Sontaran commander into retreat?”
Luke picked up his laptop.
“More or less.”
The sirens outside grew louder.
Luke stepped down from the platform.
“Come on. Let’s leave before the fire brigade arrives.”
Sirens were getting louder now.
Not distant anymore. The kind of layered emergency sound that meant London had decided something interesting was happening.
Luke pushed through the warehouse side door first.
Cool night air rushed in.
Behind him Clyde burst out laughing.
“Did you see his face?”
Luke didn’t slow down.
“Which one?”
“The commander!” Clyde said, half running to keep up. “The moment the signal looped!”
K-9 rolled beside them, servos whirring slightly faster than usual.
“Recommendation: increased velocity.”
“Working on it,” Clyde said.
They sprinted across the yard.
Behind them the warehouse doors slammed open again as human security guards finally arrived to investigate the alarms.
Luke vaulted the security gate.
Clyde followed, landing beside him with a splash.
The moment they hit the pavement Clyde lost it completely.
Full-on laughter.
“Luke,” he managed, pointing back at the warehouse, “you just told a Sontaran commander his maths was wrong.”
Luke started walking quickly down the street.
“Yes.”
“That’s insane!”
“It was accurate.”
Clyde wheezed.
“You sounded exactly like your mum.”
Luke slowed slightly.
“…Did I?”
“Oh yeah,” Clyde said, still grinning. “Full Sarah Jane mode.”
K-9’s voice chimed in helpfully.
“Comparison analysis confirms behavioral similarity.”
Luke sighed.
“Thank you, K-9.”
Ahead of them Rani appeared around the corner, phone still in her hand.
“I hear sirens,” she said. “Please tell me that means you’re finished.”
Clyde threw both arms up.
“Mission accomplished!”
Rani stopped in front of Luke.
“Well?”
Luke nodded once.
“The beacon won’t function.”
Rani blinked.
“That’s it?”
“Yes.”
She stared at him for a second.
Then she started laughing too.
“Oh my god.”
Clyde pointed at Luke again.
“He told the Sontaran commander his engineering was wrong.”
Rani clapped a hand over her mouth.
“No he didn’t.”
Luke looked mildly defensive.
“It was.”
That did it.
All three of them started laughing as they hurried down the street toward Donna’s house—the kind of breathless, adrenaline-fueled laughter that only happened when the universe had just tried to kill you and failed.
For a moment it felt exactly like Bannerman Road again.
The garden gate creaked as it swung open.
Rani slipped through first, still laughing under her breath. Clyde followed, wiping rain from his hair, the run still buzzing through him.
Behind them Luke pushed the gate closed.
The blue police box waited quietly in the corner of Donna Noble’s garden, its lamp glowing softly in the night.
K-9 rolled ahead and stopped at the doors.
“TARDIS access confirmed.”
Clyde was still grinning.
“You realize,” he said, pointing vaguely back toward the industrial park, “that somewhere right now a Sontaran commander is filing a very annoyed report.”
Luke opened the doors.
“That seems likely.”
They stepped inside.
The console room lights brightened immediately, the engines humming with that warm, familiar vibration.
“Still bigger,” Clyde said automatically.
“Yes,” Luke replied absently.
From somewhere deeper in the ship came the unmistakable clatter of kitchen activity.
Clyde froze.
“…Is that cooking?”
Luke closed the doors.
“Yes.”
Rani blinked.
“You said the Doctor was retired.”
“He is.”
“Retired people don’t usually cook inside time machines.”
Luke shrugged.
“He lives here.”
At that moment the kitchen door opened.
Donna Noble stepped into the corridor holding a wooden spoon.
She stopped when she saw them.
Three damp teenagers and a robot dog standing in the console room.
Donna narrowed her eyes.
“…Why do you look like you’ve been running from something?”
Clyde pointed behind him.
“We absolutely have.”
Rani kicked him lightly.
“Subtle.”
Donna folded her arms.
“Luke Smith.”
Luke met her gaze.
“Yes?”
“What have you done?”
Luke considered that.
“Resolved a situation.”
Donna squinted.
“Define situation.”
From the kitchen doorway behind her the Doctor leaned out, drying his hands on a towel.
He looked from Luke to Clyde to Rani, then at the faint smear of grease on Clyde’s sleeve, then at the slightly singed edge of Luke’s jacket.
His eyes softened.
“Sontarans,” he said.
Clyde blinked.
“…How did you know that?”
The Doctor smiled faintly.
“I heard the beacon attempt.”
Luke raised an eyebrow.
“You didn’t intervene.”
The Doctor leaned against the doorway.
“No.”
Donna turned toward him.
“You heard a Sontaran beacon and you didn’t go?”
The Doctor gestured lazily toward Luke.
“He did.”
Luke tilted his head slightly.
“That seems optimistic.”
The Doctor shook his head.
“Not optimistic.”
Certain.
He stepped into the console room, hands in his pockets.
“So,” he said lightly, “did you sabotage the synchronizer or rewrite the signal loop?”
Clyde stared at him.
“Those were options?”
Luke shrugged faintly.
“I rewrote the synchronizer.”
The Doctor nodded approvingly.
“Good choice.”
Rani blinked.
“You knew what he was going to do.”
The Doctor looked genuinely puzzled.
“Of course I did.”
Donna jabbed the spoon toward him.
“You let them run off and break a Sontaran deployment beacon!”
“Yes.”
“That’s dangerous!”
The Doctor gestured toward Luke again.
“He handled it.”
Luke frowned slightly.
“You sound very confident.”
The Doctor’s expression softened just a fraction.
“You’re Sarah Jane Smith’s son.”
Luke didn’t answer.
For a moment the console room hummed quietly around them.
Then Donna sighed and waved the spoon toward the corridor.
“Right. Everyone into the kitchen.”
Clyde perked up instantly.
“Food?”
“Yes, food.”
Rani smiled.
“I like this TARDIS.”
The Doctor grinned and stepped aside to let them pass.
As Luke walked by, the Doctor lowered his voice slightly.
“Well done.”
Luke paused.
“…You really weren’t going to interfere.”
The Doctor shook his head.
“No.”
Luke studied him for a moment.
Then nodded once and continued toward the kitchen.
Behind them the TARDIS engines hummed softly.
UNIT Headquarters
Early morning
The conference room lights were too bright for the hour.
Kate Stewart stood at the head of the table with a tablet in one hand, reading the incident summary for the third time.
It had not improved.
Across from her, two UNIT analysts sat very carefully still.
Mel leaned against the wall beside the screen, arms folded.
Kate finished the report.
Then lowered the tablet slowly.
“Let me confirm something,” she said.
Her voice was calm.
Which meant everyone in the room knew it was not going well.
“At approximately twenty-three hundred hours,” Kate continued, “London Fire Brigade responded to what they believed was a chemical leak at an industrial warehouse.”
One of the analysts nodded.
“Yes, ma’am.”
Kate tapped the tablet.
“Upon arrival they discovered the facility had been… evacuated.”
“Yes.”
Kate looked up.
“And during the sweep of the building they discovered evidence of—”
She tapped the screen again.
“—Sontaran military technology.”
Silence.
Mel tilted her head slightly.
“Not subtle technology either,” she said. “Beacon components. Power routing. Signal housing.”
Kate looked back at the report.
“Correct.”
She set the tablet down on the table.
“Which raises the obvious question.”
Both analysts straightened slightly.
Kate folded her hands.
“How did a Sontaran deployment beacon get constructed inside Greater London without UNIT noticing?”
The younger analyst cleared his throat.
“Technically we were monitoring the facility for unauthorized alien energy signatures—”
“Technically,” Kate interrupted calmly, “you were monitoring the facility after someone else had already shut the operation down.”
Another silence.
Mel pushed away from the wall and walked over to the screen.
She tapped a key.
A surveillance still appeared.
The warehouse floor.
Dismantled Sontaran equipment.
A partially collapsed beacon frame.
“Fire crews say the machine had already powered down when they arrived,” Mel said. “Looks like the activation attempt failed.”
Kate studied the image.
“Failed how?”
Mel shrugged slightly.
“Signal loop.”
Kate looked at her.
“That’s not a failure.”
“No,” Mel said.
“That’s sabotage.”
The room went very quiet.
Kate nodded once.
“Yes.”
She picked up the tablet again and scrolled further down the report.
“There’s more.”
Mel raised an eyebrow.
“Oh good.”
Kate turned the screen toward them.
“Security footage from the loading area.”
The analyst hit another key.
The image changed.
A grainy exterior camera feed.
Three figures running across the yard.
Mel leaned closer.
“Well,” she said.
“That’s familiar.”
Kate watched the footage carefully.
The figures were mostly silhouettes.
But one detail stood out clearly.
A small metal shape rolling beside them.
Kate pointed at the screen.
“Pause.”
The image froze.
K-9 was unmistakable.
Mel exhaled slowly.
“…That’s not subtle.”
Kate leaned back slightly.
“No.”
She studied the frozen image for a moment longer.
Then nodded once.
“I believe we have finally identified our mystery hacker.”
Mel crossed her arms.
“Sarah Jane’s son.”
Kate didn’t answer immediately.
She was still looking at the screen.
Then she said quietly,
“Yes.”
Another pause.
Mel glanced sideways at her.
“Problem?”
Kate exhaled slowly.
“Several.”
She tapped the tablet once more.
“Sontarans attempted to deploy a fleet staging beacon inside London.”
She looked back at the frozen image of Luke, Clyde, and Rani running across the yard.
“And Sarah Jane Smith’s son stopped them before UNIT even knew it was happening.”
Mel gave a small half-smile.
“Well.”
Kate looked at her.
“That can’t continue.”
Mel raised an eyebrow.
“No?”
Kate folded her arms.
“No.”
She looked back at the screen again.
Because there was one thing about the footage that was bothering her.
The way Luke moved.
Confident.
Certain.
Like someone who had done this many times before.
Kate turned to the analysts.
“I want everything we have on Luke Smith.”
Mel tilted her head.
“You’re not going to arrest him.”
Kate looked mildly offended.
“Of course not.”
She glanced at the screen again.
Then said quietly,
“I’m going to recruit him.”
And somewhere across London, inside a blue police box parked in Donna Noble’s garden, the TARDIS hummed softly.
UNIT Headquarters
Kate’s Office
Kate Stewart looked up from the tablet in her hands.
There was a man sitting in the chair opposite her desk.
He had not been there a moment ago.
He sat comfortably, one ankle resting over the opposite knee, stirring a cup of tea as if the office belonged to him.
Kate blinked once.
Then she sighed.
“You used the TARDIS again.”
The Doctor glanced up from the tea.
“Technically I walked.”
Kate leaned back in her chair.
“Through a locked UNIT corridor.”
“Yes.”
“And two security checkpoints.”
“Yes.”
“And into my office.”
The Doctor took a thoughtful sip of tea.
“Yes.”
Kate studied him for a moment.
“You know, most people knock.”
The Doctor tilted his head slightly.
“Most people don’t have a time machine.”
Mel’s voice drifted in from the hallway.
“I’m pretending I didn’t see any of this.”
Kate called toward the door without looking away from the Doctor.
“Thank you, Mel.”
Footsteps retreated.
The Doctor set the cup down.
Kate folded her hands.
“Let me guess,” she said.
“You’re here about the Sontarans.”
The Doctor looked mildly impressed.
“Well deduced.”
Kate gestured toward the tablet.
“My people are already investigating.”
The Doctor nodded slowly.
“Yes.”
Kate watched him.
“And?”
The Doctor leaned forward slightly.
“It’s not entirely your fault.”
Kate’s eyes narrowed a fraction.
“That’s an interesting way to begin a conversation.”
The Doctor shrugged lightly.
“Well, it isn’t.”
He picked up the tablet from her desk and glanced at the paused image of Luke, Clyde and Rani running across the warehouse yard.
K-9 rolled clearly beside them.
The Doctor smiled faintly.
“Good work.”
Kate’s voice stayed level.
“You knew.”
“Yes.”
“You let them handle it.”
“Yes.”
Kate leaned back.
“That’s irresponsible.”
The Doctor set the tablet down again.
“No.”
Then he looked directly at her.
“It’s necessary.”
Kate didn’t respond immediately.
The Doctor tapped the tablet once.
“You’ve identified your mystery hacker.”
“Yes.”
“Luke Smith.”
“Yes.”
The Doctor nodded.
“Sarah’s son.”
Kate’s expression softened slightly at the name.
“She spoke about him.”
“Yes.”
The Doctor’s voice remained calm.
“But you’ve missed a rather important detail.”
Kate waited.
The Doctor stood and wandered toward the window.
“When Sarah Jane Smith died,” he said lightly, “UNIT secured Bannerman Road.”
Kate nodded once.
“Standard protocol.”
“Yes.”
He turned back toward her.
“Your people catalogued everything alien in the house.”
Kate folded her arms.
“Correct.”
The Doctor tilted his head slightly.
“And in doing so,” he said gently, “they took every single thing that belonged to Luke.”
Kate frowned.
“Excuse me?”
The Doctor counted lightly on his fingers.
“Mr. Smith.”
Kate’s posture stiffened.
“Sarah’s alien supercomputer.”
“Yes.”
Another finger.
“Her TARDIS key.”
Kate blinked.
“…Her what?”
“Yes.”
“And every other strange little bit and bob Sarah collected over thirty years of saving your planet.”
Kate said nothing.
The Doctor stepped closer to the desk.
“Imagine,” he said quietly,
“if someone walked into your father’s house after he died and boxed up everything he ever owned.”
Kate’s jaw tightened.
The Doctor held her gaze.
“His files.”
“His medals.”
“His photographs.”
“His UNIT records.”
Kate’s voice came out lower now.
“That would be unacceptable.”
“Yes,” the Doctor said softly.
“It would.”
Silence hung in the office.
Then the Doctor added mildly,
“And one of those ‘bits and bobs’ Sarah collected…”
Kate looked up.
“…was her son.”
The words sat in the room for a moment.
Kate frowned.
“I’m not sure I follow.”
The Doctor’s expression softened slightly.
“Luke isn’t properly human.”
Kate stared at him.
“He was created by the Bane.”
The room went very still.
Kate leaned forward slowly.
“…What?”
“Yes.”
The Doctor folded his arms.
“They engineered him.”
“Designed him.”
“Created him to infiltrate humanity.”
Kate processed that for several seconds.
“And Sarah—”
“Saved him.”
Kate exhaled slowly.
“So he’s been hiding from UNIT.”
“Yes.”
The Doctor nodded once.
“Running around London fixing alien problems.”
“Sleeping on Clyde’s sofa.”
“Helping people.”
“And staying just far enough away that no one with a clipboard can decide to put him in a box.”
Kate looked down at the tablet again.
At the frozen image of Luke running across the yard.
The Doctor’s voice softened.
“He’s been afraid of you.”
Kate looked up sharply.
“Afraid?”
“Yes.”
The Doctor gestured lightly toward the image.
“You took everything that belonged to his mother.”
Kate sat very still.
The Doctor’s expression hardened just a fraction.
“You’re very lucky, Kate Stewart.”
She blinked.
“Lucky?”
The Doctor nodded once.
“That you’re one of mine.”
Kate frowned slightly.
“One of yours?”
The Doctor shrugged.
“I like you.”
“Your father was one of my best friends.”
“You try.”
Kate stared at him.
The Doctor picked up his tea again.
“Otherwise,” he said mildly,
“I’d be considerably more cross than I already am.”
Kate leaned back slowly.
For a moment she said nothing.
Then she looked down at the image of Luke again.
And said quietly,
“…We’re going to fix this.”
UNIT Headquarters
Operations Room
The room was quieter than usual.
Screens glowed along the far wall, showing satellite feeds, data streams, and the remains of the Sontaran beacon recovered from the warehouse.
Kate Stewart stood at the central table with both hands resting lightly on its surface.
Mel leaned against one of the consoles nearby.
Two analysts waited with tablets in hand.
Kate had been silent for nearly thirty seconds.
Everyone in the room knew better than to interrupt that kind of silence.
Finally she spoke.
“I want Bannerman Road reopened.”
The younger analyst looked up.
“Ma’am?”
Kate didn’t raise her voice.
“Everything removed from that property after Sarah Jane Smith’s death.”
She tapped the table once.
“I want it catalogued again.”
The analyst blinked.
“It already was.”
“Yes,” Kate said calmly.
“And we’re going to undo it.”
Mel straightened slightly.
Kate turned to face the room fully.
“Every item that was taken from Bannerman Road is to be returned.”
The second analyst frowned.
“Ma’am, some of those objects were classified alien technology.”
“Yes.”
“UNIT protocol requires—”
Kate cut him off gently.
“I’m aware of UNIT protocol.”
She folded her arms.
“Mr. Smith.”
Both analysts hesitated.
Mel nodded toward them.
“You heard her.”
The younger one swallowed.
“The computer was moved to a secure facility.”
Kate’s expression did not change.
“Retrieve it.”
“Yes, ma’am.”
She continued without pause.
“Sarah Jane Smith’s personal files.”
“Her equipment.”
“Her storage units.”
“Every single item that belonged to her.”
Mel tilted her head slightly.
“You’re sure about this.”
Kate looked at her.
“Yes.”
Mel nodded once.
“Fair enough.”
One of the analysts spoke again.
“And the TARDIS key?”
Kate blinked once.
“The what?”
Mel sighed.
“They found it in her desk.”
Kate closed her eyes briefly.
“…Of course they did.”
She looked back at the analysts.
“That too.”
“Yes, ma’am.”
Kate walked slowly toward the large screen displaying the warehouse footage.
Luke froze mid-run beside Clyde and Rani, K-9 rolling beside them.
She studied the image.
“You will not,” she said quietly, “place any monitoring devices on these items.”
The analysts exchanged a quick glance.
Kate turned back toward them.
“No trackers.”
“No surveillance.”
“No containment procedures.”
Mel raised an eyebrow.
“That’s a very specific list.”
Kate met her gaze.
“Yes.”
She looked back at the screen again.
Then said calmly,
“These things belong to Luke Smith.”
Silence.
The younger analyst spoke carefully.
“Ma’am… technically they were classified as alien artifacts.”
Kate shook her head.
“No.”
She pointed lightly at the frozen image of Luke.
“They belonged to his mother.”
Another pause.
Mel crossed her arms.
“And what happens when we give them back?”
Kate exhaled slowly.
“He’ll probably be furious.”
“That seems likely.”
Kate nodded.
“But he’ll be furious with the truth in front of him.”
Mel tilted her head slightly.
“You’re planning to deliver them yourself.”
“Yes.”
“That’s going to be awkward.”
Kate looked mildly unimpressed.
“Yes.”
She tapped the screen again.
“Load everything into a transport vehicle.”
The analysts nodded and moved quickly to their consoles.
Mel watched Kate for a moment.
Then asked quietly,
“You think he’ll meet you?”
Kate studied the frozen image again.
Luke running across the yard, jacket flaring behind him.
The kind of movement she had seen before.
From someone else.
“I don’t know,” she said.
“But if someone had taken my father’s things…”
She paused.
Then finished quietly,
“I’d want them back.”
Mel nodded slowly.
“Fair.”
Kate turned away from the screen.
“Let’s fix this.”
The door opened quietly.
Luke stepped into the room and stopped.
It was small.
Smaller than he expected.
A narrow bunk sat against the curved TARDIS wall, the blanket folded with almost military neatness. A wooden shelf held a row of worn paperbacks. Beside them sat a stack of reporter’s notebooks tied together with a rubber band.
A long brown coat hung from a hook near the door.
On the small desk beneath the round window sat a battered typewriter.
Luke stared at it.
“…She used a typewriter?”
The Doctor leaned against the doorframe behind him.
“Journalists did in 1978.”
Luke stepped further into the room slowly.
The air smelled faintly of paper and old machine oil.
The TARDIS hummed softly around them.
“She kept this room.”
“Yes.”
Luke ran a finger along the edge of the desk.
“You never changed it.”
The Doctor shook his head.
“No.”
Luke looked back at him.
“Why?”
The Doctor shrugged slightly.
“She might have come back.”
Luke didn’t answer.
He sat carefully on the edge of the bunk.
The mattress creaked softly.
For a moment the only sound was the low vibration of the TARDIS engines.
Luke picked up one of the notebooks.
The first page held quick, messy handwriting.
Questions.
Observations.
Half-formed article notes.
He smiled faintly.
“She never stopped working.”
“No.”
Luke set the notebook back down.
Then he said quietly,
“You told Kate.”
“Yes.”
Luke looked up.
“Why?”
The Doctor stepped into the room and leaned lightly against the desk.
“Because she needed to understand something.”
Luke frowned.
“What?”
“That she hurt you.”
Luke shrugged faintly.
“That seems obvious.”
“Yes,” the Doctor said.
“But she didn’t know.”
Luke’s expression hardened slightly.
“That’s convenient.”
The Doctor shook his head.
“No.”
He gestured lightly toward the room.
“When Sarah died, UNIT secured Bannerman Road.”
“Protocol.”
“Yes.”
“But Kate wasn’t running UNIT yet.”
Luke didn’t respond.
“They boxed everything up before she knew what had been taken.”
Luke looked down at the typewriter again.
“They took Mr. Smith.”
“Yes.”
“They took her things.”
“Yes.”
Luke’s voice stayed calm.
“And technically speaking they took me.”
The Doctor nodded.
“I know.”
Luke looked up.
“So why should that matter now?”
The Doctor considered the question for a moment.
Then he said quietly,
“Because she’s bringing them back.”
Luke blinked.
“…What?”
“Mr. Smith.”
“Her files.”
“The key.”
“All of it.”
Luke stared at him.
The Doctor shrugged lightly.
“She’s her father’s daughter.”
Luke leaned back slightly, absorbing that.
For a moment he said nothing.
Then he looked around the room again.
The typewriter.
The notebooks.
The coat on the wall.
“She would have hated them taking it,” he said quietly.
“Yes.”
Luke rubbed his hands together.
“She always said UNIT had a habit of assuming they were in charge.”
The Doctor smiled faintly.
“She also trusted your Brigadier with her life.”
Luke was quiet again.
Then he said,
“I don’t know if I’m ready to trust Kate Stewart.”
The Doctor nodded.
“That’s fair.”
Luke looked up at him.
“You do.”
“Yes.”
Luke frowned.
“Why?”
The Doctor tilted his head slightly.
“Because when I told her what happened…”
He paused.
“…she looked exactly the way Sarah would have.”
Luke didn’t reply.
The Doctor moved toward the door.
“Get some sleep.”
Luke watched him go.
Just before he left, Luke spoke.
“…Doctor.”
He stopped.
Luke looked around the small room again.
“If she really brings them back…”
The Doctor waited.
Luke finished quietly,
“…then I’ll listen.”
The Doctor nodded once.
“That’s all she’s hoping for.”
Then he stepped out into the corridor.
And the TARDIS hummed softly, like it was remembering someone it loved.
Donna Noble’s Garden
The car engine clicked softly as it cooled.
Kate Stewart stepped out and looked at the blue police box at the far end of the garden.
It was raining lightly.
Of course it was.
UNIT had supplied a transport van for the recovered items, but Kate had insisted on bringing the first box herself.
Mel leaned against the car beside her.
“You want backup?” she asked.
Kate shook her head.
“No.”
Mel nodded toward the police box.
“Because once you knock on that door you’re technically walking into a time machine.”
“Yes.”
“And possibly an argument.”
“Also yes.”
Mel smiled faintly.
“Well. Good luck.”
Kate picked up the box from the back seat.
Inside were several carefully packed objects.
Sarah Jane Smith’s TARDIS key.
A stack of notebooks.
Two small devices the analysts had been very nervous about returning.
And a familiar metal casing.
Mr. Smith.
Kate walked across the grass toward the police box.
She stopped in front of the door and knocked.
Nothing happened.
Then the door opened.
The Doctor stood there, hands in his pockets.
“Hello, Kate.”
“Doctor.”
He glanced down at the box.
“Ah.”
Kate held his gaze.
“We’re returning what never should have been taken.”
The Doctor stepped aside.
“Good.”
Kate stepped inside the TARDIS.
And stopped.
The interior space opened around her in impossible dimensions.
Mel walked in behind her and looked around.
“…Still bigger.”
“Yes,” Kate said absently.
She was looking at the young man standing near the console.
Dark jacket.
Laptop bag slung over one shoulder.
K-9 beside him.
He turned when the doors closed.
Kate had expected someone younger.
Not a child exactly, but still—
This man was tall. Broad-shouldered. Guarded.
And unmistakably annoyed.
For a moment neither of them spoke.
The Doctor watched the exchange quietly.
Kate set the box on the console.
“Luke Smith,” she said.
His eyes narrowed slightly.
“Yes.”
Kate studied him.
She could see it now.
The intelligence in the eyes.
The quiet certainty.
Very familiar.
The Brigadier had worn the same expression when he knew he was right.
“You’ve been busy,” she said.
Luke glanced at the box.
“So have you.”
Kate didn’t react to the tone.
Instead she opened the lid.
Inside, the metal casing of Mr. Smith gleamed under the console lights.
Luke froze.
Just slightly.
Kate lifted the small object beside it.
A thin brass key.
Luke’s gaze locked onto it.
Kate held it out.
“This belonged to your mother.”
Luke stepped closer slowly.
He took the key from her hand.
For a moment he simply looked at it.
Then he closed his fingers around it.
Kate watched him quietly.
“We should never have taken these things,” she said.
Luke looked up.
“You did.”
“Yes.”
He studied her face for a moment.
“You’re Kate Stewart.”
“Yes.”
“Your people catalogued my house.”
Kate met his gaze evenly.
“They did.”
Luke’s voice stayed calm.
“They catalogued me too.”
Kate didn’t flinch.
“That was a mistake.”
Luke folded his arms.
“That’s a generous description.”
Kate nodded once.
“Fair.”
Behind them Clyde and Rani watched the exchange with great interest.
The Doctor leaned against the console, saying nothing.
Kate gestured toward the box.
“Everything we removed from Bannerman Road is being returned.”
Luke looked down at Mr. Smith again.
“You expect that to fix things.”
“No.”
Luke raised an eyebrow.
Kate met his gaze steadily.
“I expect it to be the first correct decision.”
Silence settled over the console room.
Luke looked at her for several seconds.
Then he said quietly,
“You’re not what I expected.”
Kate allowed the smallest hint of a smile.
“I was just thinking the same thing.”
Kate opened the box further.
Inside was a clear containment cylinder about the size of a small case. Soft internal lights glowed faintly.
Suspended within it was a jagged crystalline structure, facets catching the console room light in shifting colors.
For a moment no one spoke.
Luke stepped forward slowly.
“…Mr. Smith.”
The crystal pulsed once.
Dim.
Unresponsive.
Kate watched him carefully.
“UNIT recovered the Xylok from Bannerman Road,” she said. “He was being stored in a secure facility.”
Luke’s jaw tightened slightly.
“He’s not just a Xylok.”
Kate waited.
“He’s Mr. Smith,” Luke said quietly. “He’s a person.”
Rani and Clyde exchanged a glance.
Luke lifted the cylinder carefully from the box and carried it to the console.
K-9 rolled closer.
“Xylok life signs detected,” K-9 reported.
Luke set the container down.
“They disconnected the interface,” he said.
Kate nodded once.
“Our analysts couldn’t replicate the system your mother built.”
Luke gave a faint, humorless smile.
“That’s because it wasn’t just a system.”
He opened his laptop.
Clyde leaned in slightly.
“So… we wake him up?”
Luke connected a cable to the containment cylinder.
“I rebuild the translator.”
Kate watched his hands move across the console.
Fast.
Certain.
Like someone who had grown up around alien machinery.
“Sarah built the original interface,” she said quietly.
Luke didn’t look up.
“Yes.”
“And you can rebuild it.”
He finally glanced at her.
“She taught me.”
Then he went back to work.
The TARDIS lights dimmed slightly as power rerouted through the console.
For several seconds the room filled with the soft hum of the engines and the quick rhythm of Luke’s typing.
Then—
The crystal flared with sudden light.
A familiar voice filled the console room.
“Sarah Jane Smith.”
Everyone froze.
The crystal pulsed again.
“Sarah Jane Smith, I detect system changes. Why am I not connected to Bannerman Road?”
Luke leaned forward slightly.
“Hello, Mr. Smith.”
The crystal flickered.
“Luke Smith.”
Another pause.
“Your voice patterns indicate you have aged significantly.”
Clyde snorted.
“Still polite.”
Mr. Smith’s voice shifted slightly.
“I detect multiple unfamiliar individuals.”
Kate stepped forward slowly.
“I’m Kate Stewart.”
The crystal pulsed again.
“UNIT.”
Luke closed his laptop gently.
“Yes.”
The crystal was quiet for a moment.
Then it said calmly,
“UNIT has historically been unreliable.”
Clyde burst out laughing.
Kate exhaled slowly.
“…Not entirely fair.”
Luke looked at the crystal again.
“You’re home now.”
The crystal’s light softened slightly.
“Understood.”
The console room settled into a more comfortable quiet.
Rani leaned against the rail and studied Luke for a moment.
Then she said casually,
“So… we should probably go to Bannerman Road.”
Luke blinked.
“We are in the TARDIS.”
“Yes,” Rani said patiently. “But the house.”
Luke looked down at the console.
For a moment he didn’t answer.
Clyde tilted his head.
“You’ve been avoiding it.”
Luke shrugged faintly.
“UNIT confiscated everything.”
Kate didn’t interrupt.
Rani gestured toward the containment cylinder.
“You’ve got Mr. Smith back.”
She pointed toward the box of Sarah’s things.
“And your mum’s things.”
Clyde added,
“And you’ve been living here anyway.”
He waved around the console room.
“So the TARDIS can park somewhere else.”
Donna leaned on the rail.
“Preferably not my garden again.”
Rani shrugged.
“Luke’s garden.”
Clyde brightened.
“Oh, that’s perfect.”
The Doctor looked thoughtful.
“Yes. The begonias would appreciate the change.”
Donna gave him a look.
Luke rubbed the back of his neck.
“The house might need repairs.”
Mr. Smith spoke from the cylinder.
“Bannerman Road systems currently inactive. Restoring operational status would be logical.”
Clyde folded his arms.
“Even the alien crystal says go home.”
Luke stared down at the console for a moment.
Then he looked at Kate.
“You’re really returning everything.”
“Yes.”
Luke nodded slowly.
Then he looked up at the Doctor.
“…All right.”
The Doctor’s smile was small but very pleased.
“Thought you might say that.”
Luke glanced toward the TARDIS doors.
“We’ll have to move the ship.”
The Doctor looked up toward the ceiling.
“Anywhere in particular?”
Rani grinned.
“Garden.”
Clyde added,
“Not the attic.”
Donna waved a hand.
“Good. Don’t ask.”
Luke laughed quietly under his breath.
The TARDIS engines hummed suddenly.
Luke frowned.
“I didn’t touch anything.”
The Doctor looked up fondly.
“No,” he said.
“You didn’t.”
The central column began to rise and fall.
Mr. Smith spoke calmly.
“Temporal displacement detected.”
Clyde clapped his hands once.
“Road trip.”
Luke rested one hand lightly on the console.
“…Home.”
And the TARDIS slipped neatly out of Donna Noble’s garden and into the London night.
The engines wound down slowly.
The central column lowered with one final soft thump.
For a moment no one moved.
Luke stared at the console.
“…That was quick.”
Donna folded her arms.
“Well you did say where you wanted to go.”
The Doctor leaned lightly against the rail.
“No,” he said mildly. “You did.”
Luke glanced up at him.
Then toward the doors.
For a moment the console room was very quiet.
Mr. Smith’s containment cylinder pulsed softly on the console.
K-9 rolled forward a few inches.
“Arrival confirmed.”
Clyde cracked his knuckles.
“Well.”
Rani gave Luke a small smile.
“Ready?”
Luke didn’t answer right away.
Finally he walked to the doors.
His hand hovered near the handle.
Then he pulled them open.
Cool night air slipped into the console room.
The familiar streetlight glow fell across the garden.
Bannerman Road.
The house stood exactly where it always had.
Brick walls.
The small front garden.
The upstairs window where Sarah used to watch the street.
For a moment Luke just stood there.
The others stayed behind him.
No one rushed.
No one spoke.
Mr. Smith’s voice broke the silence gently.
“Environmental readings confirm location.”
Luke exhaled slowly.
“Yes.”
Clyde stepped up beside him.
“Looks the same.”
“Yes.”
Rani leaned forward slightly to see past them.
“It’s been waiting.”
Kate said nothing, but her eyes moved carefully over the house.
The Doctor watched Luke instead.
Luke stepped out of the TARDIS and onto the grass.
The garden was a little overgrown.
The porch light was dark.
But the house was still there.
Still solid.
Still home.
K-9 rolled out beside him.
“Bannerman Road residence detected.”
Luke walked slowly toward the door.
He stopped on the front step.
The brass key was still in his hand.
Kate’s hand tightened slightly around the empty box behind him.
Luke unlocked the door.
The lock clicked.
The door opened.
The house was dark.
Luke stepped inside.
The air smelled faintly of dust and old paper.
Behind him Clyde flicked the light switch.
Nothing happened.
Clyde looked at him.
“Power’s off.”
Luke nodded.
“That makes sense.”
Mr. Smith’s crystal pulsed again from the TARDIS doorway.
“Restoration of house systems recommended.”
Luke looked around the dark hallway.
The umbrella stand still leaned slightly against the wall.
The coat rack still held Sarah’s old jacket.
He ran his hand once along the banister.
Then smiled faintly.
“…Let’s turn the lights back on.”
The attic door creaked when Luke pushed it open.
Dust motes drifted in the narrow beam of Rani’s phone light.
Boxes sat stacked against the sloped walls. Old alien devices. Sarah’s storage crates. A folded banner Clyde had once painted for a school event.
And in the far corner, the space where Mr. Smith’s console had once stood.
The housing UNIT had removed was gone.
But the wall connections remained.
Luke crossed the room and set the containment cylinder down carefully on the work surface.
Mr. Smith’s crystal pulsed faintly inside.
Kate stepped closer, studying the wiring panel.
“They removed the interface cleanly.”
Luke crouched beside the wall plate and opened it with a small screwdriver.
“That’s standard containment.”
Kate winced, just slightly.
Luke didn’t comment.
Instead he opened his laptop and pulled a coil of cables from his bag.
Rani crouched beside him to watch.
“You’re rebuilding the translator.”
“Temporarily.”
Clyde leaned against one of the beams.
“So… mild alien electrical engineering. Normal evening.”
Luke connected the first cable to the wall port.
Then another to the containment cylinder.
Kate folded her arms, watching the process.
“You’ve done this before.”
Luke glanced up briefly.
“My mum showed me how the interface worked.”
His fingers moved quickly across the keyboard.
Code streamed down the screen.
He rerouted the power line, bypassed the missing hardware, and built a temporary translation bridge through the laptop.
Kate watched the entire thing unfold in quiet fascination.
Luke hit the final command.
For a moment nothing happened.
Then the crystal flared with blue light.
The attic light flickered—
—and turned on.
Downstairs, lights flicked on throughout the house.
Heating pipes rattled faintly as the system restarted.
Mr. Smith spoke.
“Interface detected.”
Pause.
“Luke Smith.”
Luke exhaled quietly.
“Hello, Mr. Smith.”
The crystal brightened slightly.
“Translation interface operating at partial capacity.”
Clyde grinned.
“Oh that’s satisfying.”
Mr. Smith continued calmly.
“Bannerman Road systems restoring.”
Luke leaned back from the laptop.
“That’ll hold until I rebuild the proper console.”
Kate was still watching him.
“You recreated a Xylok communication interface with spare wiring and a laptop.”
Luke shrugged faintly.
“It’s not permanent.”
“No,” Kate said quietly.
“But it works.”
Mr. Smith spoke again.
“House status: operational.”
Clyde spread his arms.
“Bannerman Road lives again!”
Rani smiled.
“Welcome home.”
Luke closed the laptop.
For a moment he just stood there, looking around the attic.
Then Kate said quietly,
“You’re very good at this.”
Luke glanced at her.
“It was my mum’s house.”
He gestured toward the walls.
“Someone had to keep it running.”
Kate nodded slowly.
“Yes.”
Then she stepped a little closer to the worktable.
“You’ve been cleaning up alien incidents before UNIT even hears about them.”
Luke glanced at her.
“Sometimes.”
“That’s modest.”
Luke shrugged faintly.
“Someone has to.”
Kate nodded once.
“Yes.”
She extended a hand slightly toward him.
“But you shouldn’t have to do it alone.”
Luke leaned back against the desk.
His expression didn’t soften.
“I’m not joining UNIT.”
Kate nodded immediately.
“I didn’t ask you to.”
That gave him pause.
Luke folded his arms.
“Then let’s be clear about something.”
The room went very quiet.
Even Clyde stopped leaning on the wall.
Luke met Kate’s gaze directly.
“You don’t own Bannerman Road.”
Kate didn’t interrupt.
“Mr. Smith isn’t yours.”
The crystal pulsed faintly as if in agreement.
“And I’m not an asset.”
Kate inclined her head slightly.
“That’s understood.”
Luke’s voice remained calm but firm.
“If anyone in your organization decides to catalogue me again…”
He gestured lightly toward the attic floor.
“…I walk.”
Kate studied him for a moment.
Then she said simply,
“That sounds reasonable.”
Clyde blinked.
“…That was easier than expected.”
Kate ignored him.
“You’d be consulting,” she said. “Independent. No containment protocols. No classification of your home.”
Luke considered that.
“And Mr. Smith?”
Kate glanced toward the glowing crystal.
“Is clearly quite capable of defending himself.”
Mr. Smith spoke calmly.
“Correct.”
Luke almost smiled.
He looked back at Kate.
“You’ll share information.”
“Yes.”
“No surprises.”
“I’ll try.”
That earned the smallest hint of a smile from him.
Luke thought for a moment longer.
Then he said,
“I’ll help when it matters.”
Kate nodded once.
“That’s all I’m asking.”
Luke extended his hand.
They shook.
It wasn’t warm.
But it was solid.
Behind them Clyde exhaled dramatically.
“Well.”
Rani grinned.
“That went well.”
The Doctor, leaning quietly in the attic doorway, smiled faintly.
Because if the Brigadier had been standing there instead of his daughter, the conversation would have sounded almost exactly the same.
And somewhere in the walls, Bannerman Road settled around its new partnership.
