Finished it yesterday night, and still very depressed...
I had foreseen Dumbledore's death at the very beginning (I had heard the "rumour" about someone dying at the end, and remember having thought: It'll be Snape, Draco or Dumbledore).
Well... Here are my little theories:
1) I still haven't lost hope (though reduced by reading HPB) that Sirius will come back! (No! No! He can't be dead! I love him too much and nobody really knows what's on the other side of these f****** curtains! hem... sorry!
2) Snape is a "good guy", very probably in love with Lily (teenagers are weird, so the "mudlblood" thing is not that surprising). He could not do else than killing Dumbledore as he'd made the unbreakable vow. Plus, as it was said, he did not kill Harry at the end, and he kind of saved him from the other death eaters. He also gave him some sorts of "advices":
"Blocked again, and again, and again until you learn to keep your mouth shut and your mind closed, Potter!"
And another line disturbs me a little, and makes me think that Snape can't be a bad guy:
'Kill me,then', panted harry [...] 'Kill me like you killed him, you coward-'
'DON'T' -screamed Snape, and his face was suddenly demented, inhuman, as though he was in as much pain as the yelping, howling dog stuck in the burning house behind them, -'CALL ME COWARD!'
Why would this pain be for? Just a bad memmory of James at school? Or that he had to prove his courage by killing Dumbledore, as he was asked to, and he still fells bad?
3) Ginny will wait for Harry to finish off Voldemort, and they'll live happily ever after
Or she'll kick Harry's ass and they'll stay together, Voldemort or not!
4) Ron and Hermione... *sigh* We are waiting for those two since the first book, and nothing happened... They were so close in the HBP! I think Hermione is already aware of her crush on Ron, since at least the Goblet of Fire, but Ron... Well... I suppose we just have to wait a little more...
My fear is that they'll be already together at the beginning of the 7th, and we miss the details... I think I won't forgive Rowling if she does this.
5) The love stories (Harry/Ginny; Lupin/Tonk; Ron/Hermione, but also Mr/Mrs Wealey; Bill/Fleur; Hagrid/Madame Maxime, and maybe Snape/Lily (although it's a hypothetical one-way love)) will be very important in the fight against Voldemort. Dumbledore can't have made a mistake on that!
6) I'd like them to search for the Horcruxes during summer, after Harry had explained his family's story to his uncle and aunt (I see her aunt crying, and regretting all she'd done... But it's highty improbable), and go back to Hogwarts (with McGonnagall as the headmistress) in order to be unified, and to learn as much as they can to fight voldemort.
7) I agree with the idea of an "Obi-Wan Kenobi" version of Dumbledore.
That's all. Now I'm gonna read something more cheerfull, where nobody dies in the end...
