Fics like Theseus' Paradox

The Master did not die on a Mondasian colony ship. He meets the Fourteenth Doctor and they start playing. "Do you know what I was thinking when I came to your room at the Academy? I was thinking about how lazy and sloppy you are. What a dump of things I've always found at your place. Scattered books. Bundles of wires. All the stuff you dragged out of the Dead Zone. Things filled the room like thoughts clogged your brain. There was chaos all around you. That's why you studied terribly. You couldn't concentrate. There were no windows in our lecture halls so that we would not be distracted. You looked at the bare walls as if there were windows." The Doctor listened to him with bated breath, his face sharpened, his eyes were greedy. The shadows under his eyelashes are deep, like wells. Oh yes, he needs a break from running. The Master nodded. "Now you understand why you can't find dirt? You're just being sloppy." He put his face down and spat on the floor. "See," he said. "You missed a spot."
