Question: During the DADA class that Snape teaches, Hermione says that "werewolves only respond to a call from their own kind". Why, then, does the werewolf-Lupin go to Hermione's wolf call when she and Harry have gone back in time to save themselves? Does this mean that she is something other than a girl?

Question: When Harry and Hermione are rescuing Sirius, Hermione blasts open the door using a different spell than the one she used in The Philosopher's Stone to open the door to where Fluffy was. I can understand that the reason the spell would be stronger on Sirius's cell is so he can't escape and it's more secure. But the Philosopher's Stone had to be secured well, so why was the lock so easy to unlock?

Question: There's a scene in the Leaky Cauldron where an anonymous customer is reading Stephen Hawking's A Brief History of Time and stirring a spoon in his coffee cup without touching it. Is this just a random display of magic, or is it some kind of inside physics joke? I seem to remember some example (maybe about entropy?) in Hawking's book that included reference to a coffee cup, but it's been a really long time since I read it. Does anyone know what, if anything, this scene is supposed to signify?
