In HP / deathly hallows (hardback uk,page 84 1/2 way down) hermione tells harry that she has modified her parents memories to protect them.

after they escape at bill andfleurs wedding and go to the cafe on tottenham court road, they overpower two death eaters. when puzzling over what do do with them harry says to wipe their memories. ron says he has never done a memory charm. hermione says the same but knows the theory.( page 139) How did she modify her own parents memories???

Page 441 - Having just esacped gringotts on a dragon and leaping off into a lake hermione pulls out "clean dry robes". Harry, Ron and Hermione all change then drink the juice. forward to page 445 - harry just recovered from a vision of voldemort. "He struggled up,shivering,vaguely surprised that he was still wet to his skin"

Did he fall in the lake? some may argue that it was sweat, but if this was the case he would not "still" be wet, as it would have happened when he was unconcious, and indicates it was from his previous dip in the lake!
