There's a a monster of a minotaur clopping away somewhere in the distance, but it's not like he's ever been scared of monsters. He was not scared of anything, in fact. Amy had her Weeping Angels, and Rory had his clowns, but The Doctor had no nightmares waiting for him in that empty hotel.
Not even what lurked behind the door in front of him.
He can hear the minotaur again, he can feel the shake of the walls as it's
massive horns scrape dust onto the carpet, but he still can't seem to move. The door in front of him is marked "11" and even though the whole hallway is cast in light, it seems to leak darkness from each sharp letter.
The minotaur is closer now, it's breath is steaming against his neck. He has no choice but run into the room and pray for safety.
It takes all the strength he has to twist open the door and slam it shut against the minotaur. He exhales the breath that had been scratching away, held in his throat for what seemed like forever.
And then he turns around to face his nightmare.
Somewhere in the distance, there is a monster of astronaut waiting for him. But The Doctor has never been afraid of monsters before, and he isn't going to start now.
