Oh I'm so happy with ron and hermione getting together!
I know Harry was the only one to survive the curse - but there are other ways, like Dumbledore could have captured a death eater and put him under the Imperius Curse and made him take Polyjuice potion! Or, and I hate to say this, but Dumbledore had to have killed some death eaters or something at some point, maybe he had a horxcrux of his own?
Oddly enough, i like snape, I always did, even though I hate how he and harry detest each other.
I also have a werid feeling Dumbledore is going to end up being related to harry, or harry is going to be the descendant of Godric Gryffindor...
