[Which the Doctor's not missing, but he ignores it. It's up to him what he decides to wear, after all. And he knows he would be feeling more uncomfortable in the other Doctor's brown suit than he's feeling in this other outfit. He'll just have to make do until he finds his own clothes.]

[Right, speaking of finding things. He snatches the pair of blue Converse off the rack and speaks while tying his shoelaces.]

Now that we're all dressed, do you think we could try and find out where my TARDIS ended up? Even if we're going to stay around each other for a while, I'd like to know where she is.

[He's not exactly worried; she can take care of herself. But being in this other TARDIS that is like his own but not, it's making him a little nervous. If he's going to stay here and help, he wants his own TARDIS around as well.]
