The different incarnations of the Doctor in their respective Hogwarts Houses. ;) Though actually...they're all the same man...so how does this work?!
they both had to laugh, because they know that unknown, the monsters, the running is the best part. No chance is either of them going to give that up. No way they're just going to ignore whatever is going on here.
But remember the Doctor's face in this scene. He is not overjoyed at the reunion. He is shocked at what his companions have become. Martha Jones, willing to destroy her race to save the Universe, just like the Doctor. And Rose Tyler, cheering it on. They have become reflections of himself, and it pains him.<---- pinned for the comment
