The Doctor's steps clashed like a staccato among the corridors of UNIT. Missy wasn't far in front, seemingly swaying to the waltz in her head. He kept an eye on her (although you could never say it wasn't an affectionate eye) but was soon...way too distracted for that. A gloved hand yanked him into another room without warning and he soon saw himself in a...lab? That would normally be weird, he thought, but this IS UNIT we're talking about.
"My dear Doctor, how charmed I am to-" The Doctor managed to get a glimpse of grey jacket before putting two and two together. Well, if he wanted an encounter, then an encounter is what he'll get. The Doctor quickly took control, grabbing the lapels of the Master's suit blazer and pinning him against the lab bench. "Why did you drag me in here? Were you looking for a fight?" He growled, getting closer and closer. "Maybe I just wanted to say-" The Master responded in a remarkable silvery tone, before getting sucker punched square in the jaw.
He fell onto the floor, blood starting to pour from his mouth as he stood up, spitting a tooth out before smirking. Doctor, how unkind. The master spoke via telepathy, the words aching in the Doctor's head. Must be time to show you who's really the fighter between us. The Master tackled the Doctor into the side of the bench, letting whatever chemicals were behind him seep into his jacket.
Fortunately, the Doctor had a little bit of a grace period. Unfortunately, the chemicals were corrosive. Concentrated hydrochloric acid was burning through the clothes and then into his skin, a paroxysm of pain raking through him. Despite his, he kicked the Master straight into a set of shelves, giving him time to lift himself off the piles of broken glass and toxins and blood.
You...you've done better than that, Koschei. The Doctor panted as the Master slowly dropped to the floor, blood gushing from his head. As he fell, the Doctor could notice the stack of now shattered mortars and the large shards of porcelain in the Master's head. Oh, you don't bite like you used to. The Master slid over to the Doctor, slashing into the Doctor's leg and making him come down to his level. Blood now covered the floor as the Master exchanged blows to the Doctor's head, until it looked as beaten up as his own. Blood spilled down his nose and mouth.
Are you finished? The Doctor shouted, sending painful ripples down the Master's spine as he took the psychic blast of the message. "Gladly." The Master smirked, keeling over the Doctor and snogging him senseless. The Doctor's regeneration energy stores kicked in, and as they kissed, the acidic touch of the Doctor's back began to fade away. The clothes were another story, but that could easily be fixed. The Master's black eye also healed, but the bloody taste of their somewhat lustful embrace stayed. As they parted, the Doctor reached for the table, wobbling as he stood up and then offered the Master his hand. Taking it hesitantly, they gazed at each other, the aftertaste of each other's blood on their absent tongues. The Master kissed the Doctor's bruised hand - the one that started this whole mess in the first place - leaving it freshly healed but still scarred.
The Doctor took it as his time to leave, and he smirked at his past friend before exiting the room. As he left, the Master sighed and began to clear up the mess, before noticing his reflection in the mirror. And the bite mark only just clearing up on his neck. He shrugged and continued to clean, wiping his mouth every so often.
