Chapter Text
The cold was as biting as a wild dog.
It bit first at Severus’s ankles—sharp, needling stings that climbed, slow and consuming, like winter vines winding up a trellis. His boots had long since failed to shield him from the dungeon floor’s glacial bite, and now every shift of weight sent the ache deeper into bone. He forced himself not to react. Not to shiver. Not to let either of the two men sharing the dungeon see the way the cold scraped at him, hollowing him out with each passing breath.
The dungeon around them hummed with deadened magic. Not an active vibration, but the heavy, pressing silence of wards so absolute they seemed to swallow sound. Their wands were useless here —even the ambient hum of suppressed magic prickled against Severus’s skin, disrupting the instinctual muscle memory of spellcasting before one could so much as lift a hand.
It would have been impressive if it weren’t infuriating.
Or freezing.
“Bloody hell.” Sirius muttered through chattering teeth, breath fogging in front of him. “Who’d choose below 0 as room temperature?”
Severus didn’t say a thing, not considering the question intelligent enough to warrant an answer. Instead, he kept his steps even and controlled. Measured. Anything to keep the cold from locking his knees. Anything to keep his traitorous body from shaking.
The wall to his left was slick stone, rimed with a thin layer of frost. His glove —charmed for warmth, supposedly— did nearly nothing to blunt the cold that radiated from it. He let his fingertips skim along the edge anyway, searching for engraved lines, hidden seams, and embedded runes. Anything.
Behind him, a soft shuffle of fabric signaled Sirius and Remus shifting closer to one another. The sound was small, but in the deadened quiet, it snapped at Severus’s nerves.
“Move closer,” Remus murmured, voice thin. “You’re shaking.”
“Not shaking,” Sirius muttered, though it was blatantly untrue. His breath stuttered with every exhale.
Severus did not look. Would not look. He didn’t need to witness their pathetic huddling to know it was happening. The temperature was dropping by the minute, and even his own layers—cape, robe, inner tunic, all charmed—were failing to keep up with the cold.
But he refused to fold. Half-frozen or not, he would not allow Black the satisfaction of seeing him lose control of his own damn muscles.
A dull thud sounded behind him. Sirius had scooted nearer to Remus and settled shoulder to shoulder with him. Lupin muttered something grateful and leaned slightly into the touch. Their shared heat made sense. Their sentimental Gryffindor camaraderie, less so.
Severus clenched his jaw and moved on.
The dungeon was circular, which was both unfortunate and intentional. No corners to hide secrets in. No alcoves, no structural weaknesses that might crack under pressure. The walls curved seamlessly around them, each block fitted with the precision of a master artisan—or a paranoid wardcrafter.
Only the ceiling had any promise. High, arching, and interrupted by faint carvings so shallow the frost nearly hid them.
“Find anything?” Remus asked weakly from behind him.
Severus didn’t turn, didn’t answer. Instead, Black took his spot. “Stone. And more stone.”
To that, Severus huffed. “Brilliant observation.”
Black ignored him —unexpected— and Severus craned his neck upward, studying the faintest hint of symbols etched into the ceiling’s center. The frost made them hard to read, but the curves suggested celestial motifs. Radiating lines. A circle broken by smaller points.
Sunlight?
It couldn't be. Ridiculous. Wards this old—or this innovative—didn't rely on solar cycles.
… Except it was the type of cliché ward-controlling system that people tended to discard due to being too obvious.
But he needed more information before speaking. Hypotheses were useless without proof, and proof required a clearer view. He took a step back, assessing angles.
A violent shudder wracked him, sudden and sharp, betraying the hours he’d held himself taut. He swallowed it, forced his spine straight, and willed his legs steady.
Behind him, Sirius noticed.
“Tired of pacing already?” Sirius called out. “Or did the cold finally catch you, Sniv—”
“Sirius.” Remus’s voice snapped through the air with a quiet authority.
Somewhere between incessant walking and exhaustive checking, Lupin and Black seemed to have sat down, cuddling close. Severus felt their eyes on his back, and the humiliation simmered—an unpleasant heat, but heat all the same. “Unlike you,” he said evenly, “I’d rather not just sit and whine.”
Sirius made an indignant noise.
Remus sighed. “Both of you, please—”
“I’m not whining.” Sirius muttered.
“You’re whining.” Severus said at once.
Remus pinched the bridge of his nose, breath fogging out in front of him. “How about we don’t fight in the freezing death trap?”
“Fine.” Sirius said, though the tension rolling off him said otherwise.
Severus resumed pacing, partly to shut them out, partly because movement was the only shield against the cold’s creeping invasion. His hands were numb. His jaw ached from clenching. Each inhale scraped like ice along his lungs.
He forced his mind onto the carvings instead. Circles, rays… no, not rays. Lines representing something else. Direction? Progression?
“Maybe there’s a trigger,” Remus suggested weakly. “A phrase, a specific motion—”
“Already tried half of that.” Sirius muttered, rubbing his hands together. “Unless you want me to start singing at the wall.”
“Please don’t.” Severus said sharply.
“You’d prefer freezing to death in silence? Figures.”
“I’d prefer freezing to death without having to listen to you.” Severus snapped.
Remus exhaled sharply. “Can we—”
But then he cut himself off with a small noise of discomfort. Severus risked a brief glance. Remus was pulling his coat tighter, but his fingers were stiff and slow. Sirius leaned closer, their shoulders pressing together for warmth.
Severus looked away.
The frost on the ceiling had thickened, making the carvings harder to read. That shouldn’t be possible. The temperature shouldn't drop quickly enough for new ice to form so visibly.
Unless…
Unless the dungeon was reacting to the lack of sunlight. Absorbing the cold of the subterranean rock around them. Amplifying it.
A grim, unwelcome suspicion began threading through his thoughts.
“Severus.” Remus called softly.
He did not respond.
“Severus,” Remus said again, eyes following his pacing. “You’re going to wear a track on the floor.”
Severus’s lip twitched. “If I do, perhaps it will reveal a mechanism to open the door.”
“I meant that you’re going to exhaust yourself.”
“I am well aware of my limits.”
“I don’t think you are.” Remus murmured.
Sirius snorted. “He’s constitutionally incapable of knowing when to stop.”
Severus turned his head just enough to glare over his shoulder. “You would be the leading authority on wild roaming, Black. Spare us your expertise.”
“Glad to see the cold hasn’t frozen your tongue.” Sirius muttered.
“I assure you, if anything is frozen, it is the empty cavity you call brain.”
“Severus.” Remus said again, but more firmly, almost worried.
“What?” Severus snapped.
“You’re shaking.”
He froze—just enough for his body to betray him with a hard involuntary shiver.
Mortification flushed through him hotter than any warming charm could have. He tore his gaze away and resumed strolling before either of them could say anything else.
Of course he was shaking. The dungeon’s temperature was plummeting as the hour marched closer to midnight. Their breath fogged in the air like smoke. Frost gathered at the edges of their sleeves. Their coats might as well have been parchment for all the heat they retained, even if the warming charms were still taking effect.
The ceiling carvings glinted faintly in what little ambient light the room had.
Sunlight. Sunlight. The thought kept circling, hovering like a moth over a flame. Lumus solem could have taken them from there.
But without magic, it was a waiting game.
And waiting meant freezing.
He hated it. Hated the stillness. The vulnerability. The fact that Black and Lupin, of all people, were the closest sources of warmth in the room—and that his increasingly sluggish limbs were starting to betray him.
He pulled his cape tighter around him and continued stalking the perimeter.
Minutes blurred. Then nearly an hour. Sirius and Remus spoke quietly between themselves, trading complaints and attempts at humor that grew weaker as their lips numbed.
Eventually, Remus tried again.
“Severus,” he said, voice a little hoarse. “Come sit down. You’re wasting energy.”
“No.”
“You’re freezing.”
“So are you.”
“Yes.” Remus admitted. “But we’re conserving heat. You’re…” He gestured weakly at the circle Severus was walking. “Doing… whatever that is.”
“Searching.”
“For what? A miracle?”
“For another exit.”
“You won’t find it by walking yourself numb.”
“It’s my body,” Severus bit out. “I’ll do what I please.”
“Merlin, you’re insufferable,” Sirius muttered.
“And your opinion is irrelevant.”
The two glared at each other with the kind of frost that could rival that of the dungeon.
Remus sighed again, defeated. “Fine. Do what you want.”
He did. And he obviously didn’t need permission.
He did. Until his legs began to tremble beneath him—not from cold this time, but from the strain of refusing to succumb to it. His knees threatened to buckle. His fingers had lost feeling entirely.
At some point—he wasn’t even sure when—he stumbled. Just a fraction. Barely half a second.
But Sirius saw.
“Oi. Sit down before you fall down.”
“I am not sitting near you.”
“Then sit far away. Just sit somewhere.”
“I said no.”
“Stubborn bastard.” Sirius muttered.
“Not more tha—”
“Both of you, stop.” Remus snapped, sharper than before.
The sudden authority in the usually gentle man’s voice stunned the room into silence.
The quiet hung there, thick as the cold.
Then Remus slumped back against the wall, exhaustion dragging at his features. “This is pointless. All of it. Just —just shut up.”
Severus hesitated.
Just for a moment.
Then, without a word, he retreated to the farthest corner —well, not an actual corner, as the room was circular, but the furthest place— he could reach, which wasn’t far, and lowered himself to the floor.
His cape bunched awkwardly beneath him, the stone stealing heat from him in seconds. He tucked his knees to his chest to keep what little warmth remained.
The cold gnawed at him relentlessly.
He pulled his hands between his thighs, hiding them. Shame burned through him—shame that they might see how badly he trembled, that they might hear his teeth chattering no matter how tightly he pressed his jaw.
He set his head back against the wall, breath catching on each inhale.
Across the room, Remus and Sirius murmured quietly—trying to distract themselves with talk of warm fires, thick blankets, things they wished they had.
Severus tried to listen. Tried not to succumb to the creeping numbness. Tried not to fade.
He failed.
His awareness dulled. His limbs grew heavy. The cold seeped past his defenses and coiled around the edges of his consciousness until his body no longer responded.
“Severus, come on.”
Remus’s voice was close. Too close.
A hand shook his shoulder, insistent. Severus tried to blink, but his eyelids were so heavy, it pained him to even make the effort to pry them appart.
The shaking increased, and another hand joined it, poking his cheek.
“Come on, Snape, don’t you dare die on us.” The voice trebled, and the hand soon cupped his cheek. “You absolute git.”
Severus blinked slowly, vision thick with fog. Purple lips. Remus’s wide eyes. Sirius’s frown. The two of them kneeling in front of him.
Couldn’t process anything except the cold.
Remus’s voice sharpened. “He’s unresponsive.”
“Ngh—” Severus attempted, but the words barely scraped out. His tongue felt thick. Slow and sluggish.
Sirius swore under his breath. “Bloody hell. Let 's move him. Now.”
Severus tried to protest as they touched him—hands on his arms, dragging him upright—but his limbs were useless.
Humiliation flickered and died just as fast under the exhaustion.
They shifted him, pulling him away from the freezing wall, sandwiching him between their bodies. Warmth pressed at his sides. Foreign. Terrifying. A shame it was also a necessity.
Remus’s voice trembled. “Don’t you dare fall asleep.”
Sirius shoved something into Remus’s hands. “Check his pouch—see if there’s anything, anything at all—”
Remus went to forcefully rip it open, sure that the charm that kept it either opened or closed wouldn’t be functioning. Instead, the push slid it open to its fullest, the ruffle of the fabric against the rope fast and hissing.
Remus imagined a blanket, focusing all his attention on the fake image and crossing his mental fingers that Severus had something similar in the pouch. Then, he dipped his hand in its unknown insides.
They lucked out. There was a small blanket, barely enough for two, and a definitive stretch for three. But they made do, draping it over themselves, forcing Severus beneath its center.
More thinking. More searching.
They found a charm-warmed thermos of tea.
Remus held it to Severus’s lips.
“Drink.” he whispered. “For Melin’s sake, you can’t die here.”
Severus, barely there, swallowed weakly. The liquid scalded in comparison to the air around him. It pulled him back from the edge, but only slightly.
“That’s good.” The voice was thick and raspy, a bit erratic. “That’s really good, darling.”
Eventually, his head sagged sideways, resting against Remus’s shoulder despite his best attempts not to. Someone shook him again, as insistently as he had woken up to before, but Severus didn’t react.
He drifted.
Warmth did not return quickly.
It seeped in unevenly, as if reluctant to inhabit Severus’s body again. Tiny pinpricks needled at his fingertips first—painful, almost as burning as the tea. His legs remained numb slabs beneath him, distant and unresponsive. His face felt carved from ice.
But heat pressed in at his sides, steady and persistent.
Two bodies.
Two people.
Too close.
He drifted in and out, awareness flickering like a candle in a draft. Each time his consciousness rose, it met the same tableau: Remus’s anxious profile, Black’s tense jaw, the tight grip they each had on him to keep him upright.
He would have recoiled if he’d had the strength. He would have snarled, maybe lashed out. Anything to protect the fragile scrap of distance he would normally defend at all costs.
But his limbs would not respond.
His pride was a distant thing, muffled by the cold and the steady, aching shivers that began to pulse through him again. The tiny tremors were gathering into more violent shuddering.
Remus held him a little tighter. “That’s a good sign,” he murmured, mostly to himself. “Shivering coming back means you’re warming up.”
Sirius rubbed his own arms briskly, trying to bring heat to his fingers. His breath fogged the air. “Merlin. He looks like hell.”
“Be quiet,” Remus said, but not harshly. “Here—more tea.”
Severus blinked hard, vision blurring and unblurring as the thermos appeared again near his mouth. Remus tilted it, coaxing small sips from him. Warmth pooled in his throat, spreading downward in lazy waves.
He swallowed. Barely.
His voice, when it came, was a whisper rasped raw. “W… where…?”
“Your pouch,” Remus answered softly. “You had it.”
Something flickered in Severus’s sluggish mind.
He had it. Of course he had it.
He should have checked if he could open his pouch. He always checked it, it had become almost a nervous tick. And yet he hadn’t even thought to reach for it earlier. Idiotic. Witless. Asinine.
A familiar flare of disappointment cut through the foggy mess of his mind.
His voice was breathy, barely audible. “Foolish… of me.”
Remus shook his head quickly. “We were freezing to death, Severus. None of us were thinking perfectly clearly.”
Sirius huffed. “Maybe if he had sat instead of pacing like a caged animal...”
Severus wanted to glare. Wanted to snap back. Wanted to remind Sirius Black that he was currently pressed far too close for dignity, let alone civility.
But his eyelids drooped.
Another shiver tore through him. It was violent, rattling, as if his skeleton were trying to shake itself free of his skin.
Remus steadied him at once. “Good. Keep shivering. Can we check your pouch again? It felt like an invasion of privacy, so we didn’t keep looking.”
“It’s— It’s fine.” Severus muttered, teeth chattering uncontrollably. He couldn’t muster the memory of what he had packed, but there might be something else there.
Remus tried summoning a few more things: coats, jumpers, cardigans. Even winter socks, if that could dim the biting pain of their toes. Finally, their new inventory consisted of:
“A scarf,” Sirius breathed, surprised. “And another cape.”
Remus exhaled with relief. “Thank Merlin.”
Severus managed a weak frown. “I… packed those.”
“It’s brilliant.” Remus said quickly, as if afraid Severus might misinterpret praise as mockery. “We needed them.”
Sirius shook out the scarf—long, wide, heavy wool, generous enough to lay across the floor. “We should sit on this,” he said. “Get us off the stone.”
Remus nodded. “And the cape can cover our legs.”
They moved with clumsy, cold-stiffened effort, spreading the scarf beneath them and shifting Severus carefully onto it. The wool immediately blunted the worst of the stone’s chill. The cape went over their legs, anchoring heat closer to their bodies.
“This is better.” Remus murmured, settling on Severus’s right side again. “Much better.”
Sirius sat heavily on Severus’s left, his shoulder pressed to Severus’s. He grunted. “Warm enough for you, Snape?”
Severus forced his jaw tight to stop another bout of teeth-clacking. “Needless… concern… Black.”
“Not concern,” Sirius muttered. “Just don’t want you dying on us. Again.”
“How noble.” Severus rasped.
“Shut up.”
Remus closed his eyes briefly, exhaustion dragging at his features. “Both of you… please. Not now.”
Their breath intermingled in soft clouds of fog. The blanket over their shoulders helped only a little, but it was something. The tea warmed Severus’s stomach, though not yet his limbs.
The shivers kept coming, an erratic mix of small and violent, and each one startled both Sirius and Severus.
“How long… was I out?” Severus asked, the words slurring slightly.
Remus sighed. “Long enough to worry us.”
“You worry too easily.”
“You nearly died.” Remus said sharply.
Severus tried—and failed—to lift his chin. Surely he hadn’t been in such a bad state. “That’s an overstatement.”
Sirius snorted. Remus scowled.
But Severus didn’t have the strength to press the issue. He barely had the strength to hold his own neck upright. His head dipped again, and this time, when it rested against Remus’s shoulder, he didn’t immediately try to pull away. He couldn’t.
His body felt both too heavy and too hollow. His thoughts drifted. Time blurred.
Heat—such as it was—began to settle between the three of them, a mingled pocket of breath and body warmth as the dungeon chilled into night.
Hours passed.
At some point, Severus must have slipped fully under again —he wasn’t entirely sure— but the moment he clawed his way back into awareness, his whole body was seized by a sudden, brutal tremor.
A shock of shivering so intense it dragged a gasp from him.
Sirius jerked awake. “What the—?!”
Remus stirred too, blinking blearily. “Severus?”
The tremors kept coming, uncontrollable, as if every muscle had decided at once to convulse.
Severus tried to push himself away —instinctual panic shooting through him at the proximity— but his limbs were treacherously slow, wobbling under him. He couldn’t stand. Couldn’t crawl. Couldn’t do anything except press back against the scarf-covered floor and breathe in short, terrified bursts.
“Easy.” Remus murmured, reaching toward him.
Severus flinched violently.
“Don’t—” His voice broke. “Don’t touch me—”
“You’re okay” Remus said softly. “You’re just cold. It’s fine.”
It wasn’t fine. None of it was.
He was trapped. Half-conscious. Surrounded. Vulnerable. And pressed between two people who, for most of his life, had been synonymous with danger.
His heart thudded erratically, kicks of adrenaline made useless by stiff limbs.
Sirius held both hands up in a gesture of peace. “Hey —no one’s going to hurt you.”
Severus shot him a look of raw disbelief.
Sirius grimaced. “I mean—currently. We’re not fighting right now.”
“Wonderful reassurance.” Severus bit out through chattering teeth.
“Here.” Remus said gently, offering the thermos again. “Drink.”
Severus tried to take it.
His hands shook so violently the bottle rattled between his fingers, clattering softly. He couldn’t lift it. Couldn’t hold it steady. Could barely keep it in his lap without dropping it.
Humiliation crawled up his throat.
Remus steadied the thermos with one hand, keeping it from tipping. “Just keep your hands on it.” he murmured. “Warm your fingers.”
Severus swallowed hard, staring down at his hands—pale, trembling, useless.
“Where…” he rasped, jaw twitching, “did you… get the tea?”
Remus and Sirius shared a worried glance over Severus’s hunched figure.
“Your pouch,” Remus said again. “You already asked us, do you remember?”
A pulse of self-directed anger crackled through Severus. “I should have… checked.”
“You were freezing.”
“I should have checked.” Sharper this time. Self-condemnation cutting deeper than the cold ever had.
Sirius rolled his eyes. “Oh for—Snape, you were half-dead. No one’s judging you for forgetting a bloody pouch.”
Severus opened his mouth—maybe to argue, maybe to defend himself, he wasn’t entirely sure—but another tremor shook him too hard for speech.
Remus leaned in. “Don’t talk. Warm up.”
“S… scarf?” Severus managed.
“Already using it,” Sirius said, patting the floor beneath them. “Your cape too. Saved our arses.”
Slowly—minute by minute—the violent shivers eased into smaller ones. Not gone. Not even close. But less overwhelming. Less all-consuming.
The three of them huddled under the small blanket, legs covered by the coat, sitting shoulder to shoulder in the fragile warmth they’d cobbled together.
Remus rubbed his hands together, trying to generate heat. “We’ll make it until sunrise.”
Sirius nodded reluctantly. “Yeah. And then that bloody door better open.”
Severus leaned back against the cold stone, breathing hard but steadier.
He didn’t trust the dungeon. Didn’t trust Sirius. Nor Remus. But the coat over their legs… the scarf beneath them… the blanket around their shoulders… and the warm tea in his lap… These things he could trust: tangibles, tools.
Sirius yawned, exhausted. “Tell me again how we ended up in this freezing hellhole.”
“No stories.” Severus muttered. “Just… quiet.” Remus smiled faintly.
They shifted—uncoordinated, clumsy—until they found a configuration that allowed Severus to lean without collapsing, and the other two to hold heat without smothering him.
Their legs pressed together under the coat. Their shoulders touched. The blanket draped unevenly but warmly over all three.
The dungeon hummed quietly, as though listening.
Little by little, their breathing synchronized. Heat pooled between their bodies. The cold receded enough to make space for rest. And beneath that thin blanket, on the scarf spread across the frozen floor, the three of them slipped into an uneasy yet much-needed sleep.
