"I know just the place."
In some crazy, twisted way, there had to be humour in this. Somewhere, deep down, the Doctor was sure of it, there had to be someone who would find this all sort of hilarious. The sheer irony of it all, that Koschei was going to travel with the Doctor centuries before he would all but beg to go, and the Doctor was going to travel with Koschei centuries after he had constantly turned the Master down for that same thing... if it were happening to anybody else the Doctor would likely point it out with an amused grin and think himself quite clever for having realized it.
It's not, however, happening to anybody else, so the Doctor decides against pointing anything out. Instead, he leads Koschei through the neverending maze that is the Multiverse back to his TARDIS. Smiling -- because it always is comforting the few occasions when he gets to wander back into the old blue box without having just escaped from some world-ending catastrophe or the like -- he fishes the key out of a pocket and opens the door.
"After you," he says as he steps aside to allow Koschei in.
