Well, I have to say I was impressed with some things but unimpressed with others...
Dobby's death made me fill with tears, something that always made me laugh was people saying "omg I cried when Dumbledore died!" or something daft like that, but my eyes actually filled up with tears when I read Dobby died!
So what was the deal with Snape? Was he a vampire?
Major thing: What was it that Snape did to gain Dumbledore's trust? Was it just that he showed remorse and that he had a thing for Lily? It wasn't the patronus because he showed DD that just before the start of book 6 (DD's withered hand).
Was Nagini actually a horcrux or was Harry her replacement horcrux unbeknown to Voldemort?
Upon finishing the book it's left me with more questions, which I'm happy about really.
What was the point of Grawp? He annoyed me so much, turns out he didn't have any major role to play. Kreacher turned out to be a nice house elf once you got to know him
Who was the one who would do magic later in life under extreme circumstances?
So many questions...
