Ahhh... my all-time favourite topic. Even my username Lily_Windsor is actually my Harry Potter ater-ego, as in I originally created my character Lily Windsor for HP RPG, HP fanfic and HP anything really. So, yes, massive fan here.
I normally go to the midnight book releases all dressed up, but this year i'm going to be working at a US summer camp (leaving in 17 days!), so although excited that i'll be in the States, i'm pretty disappointed that i'm going to miss the book 7 release parties! And the Ootp Premiere too! I'm always one of those screaming fan girls (i'm 22) that stands outside Leicster Square Odeon for hours waiting for the stars to arrive!
I don't think Snape is good - as in, he isn't a good person. Like Harry, I despise him. But i'm willing to entertain the possibility that he's working for the Order. That being said, I still like to believe he's an evil, Death Eater slime ball, and for ages I was convinced he was.
But when I read Mugglenet.com's Book 7 Theories book, they presented a brilliant argument for both sides. And I have to say that there does seem to be more evidence that he was working for the Order than vice-versa. But still, I hope he's a DE so that I can spend the rest of my life justified in hating him!
