Question: I don't understand something about the last part of the movie. Before they going back in time, they are leaving Hagrid's hut and watch somebody pretending to eliminate the hippogriff. Shouldn't they've seen Harry and Hermione rescuing the hippogiff before? Because they were observing until the bad people came outside Hagrid's hut. Or do we must assume that they were rescuing the hippogriff in the meantime they were running behind the rocks?Loesjuh1985
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?
Question: Time travel question: Harry has been saved after the transformation of the werewolf because of a howl. However, this only happened because of their time travel, so the "first run" is maybe supposed to end somehow differently - e.g. Harry having been killed by the werewolf, making the scenario at the hospital ward unable to happen at all.
Question: When Hermione is using her Time Turner to attend multiple classes scheduled at the same time, she appears out of nowhere in the middle of the lessons. For this to happen, she must be travelling to the classroom after the lesson and then using the Time Turner in the empty classroom to send herself back. Is there any reason why she does it this way (rather than just travelling back to before the lesson and then entering the classroom with the others)?Moose
