Corrected entry: When the Hogwarts Express stops and Ron turns to look out the window, Hermione says "Ouch Ron, that was my foot". However, in the next shot, Ron's feet are nowhere near Hermione's. He would have had to have been leaning in order to reach her foot, and he's sitting up pretty straight, too fast for it to change in one shot.

Correction: It's pretty dark and Hermione might have mistaken a big shape for Ron.
