WHat I'm wondering is about the title for the next episode. "Let's kill Hitler". I have no idea how that relates to the previous episode. Someone on another forum suggested that it could be a metaphor; the Doctor is Hitler, and those army men--as well as the Headless Monks--are trying to kill them. Also I'm curious as to how River never knew about the girl in the spacesuit, because I'm pretty sure they're the same person.
