Well, I'm finally out of Snape's head. I liked that part, it was great to see snippets of the past events from Snape's perspective. Dumbledore's request to have Snape kill him makes a whole lot more sense now. It also makes sense that Snape would not damage his soul as his intent would be mercy and duty. The doe patronus also now makes sense. I didn't think that Snape's patronus would be a doe (I thought a bat), but the clue was right there in book six with Tonk's patronus. When Snape said 'always' I thought I could hear the distant sound of a thousand Snape fans all swooning at once. That sort of stuff plays well in books, but in real life I'd probably be thinking "Dude, you've got to get over it". Well, Snape did play in a role in Lily's death, so I'll give him a pass on the lifelong obsession.
Of course the memories are as much or more about Dumbledore. Aberforth's perception of Dumbledore comes into sharp focus in these events. Dumbledore appears to be using people like pieces on a chess board and Harry is the piece that has to be sacrificed in order to win.
The thing is I still don't think Harry will be dead at the end, but I'm not sure how that will work out. He has a piece of Voldemort's soul in him (I knew it!) so maybe the killing curse only rips one soul from the body and Voldemort's, the weaker soul, will be the one ripped away. That would make complete sense to me. Then Harry has to find a way to defeat the two pieces of Voldemort's soul left. Plus there's that thing about the wand that chose him being a bit fat symbol of rebirth.
Anyhow I'm leaving off with Harry still in the headmaster's study contemplating his impending death. Buck up buckaroo, you're going to be alive at the end of the book. At least I think so. I'm be pretty shocked if he wasn't.
