The Andrew with the knife stands up, rubbing his neck a little with his free hand and trying to make sense of the scene before him. All the Jameses have scrambled their positions while he was looking away -- he can make a guess according to which one's doing what, but there's a more direct way of dealing with this. "Which one of you is the Doctor?" he demands. He could have asked which one was James, but apparently they're all James -- just one moreso than the other two.

"Drop the knife!" says the other Andrew suddenly, looking up from where he has Ambrose 'pinned' by his wrists. The two give each other matching wild-eyed looks, thinking rather dark thoughts about who the other Andrew must be, and the knife remains decidedly un-dropped.
