My bedroom has a door in it that connects to my home in England. My... uh... friend... has a door in his hotel room that connects to his home in Chicago." He's quiet in thought for a moment. "I suppose there could be a room reserved for you, which would have a door in it that connects to wherever you come from too."
He shrugs and smiles. "I gave up wondering about this sort of crazy thing about twenty years ago, when I found a book on the fantasy shelf of my bookshop, and it was about me." He pauses. "There's books about you too," he adds. "At least, if that's the Tardis, you must be the Doctor, right?"
