I think Hogwarts will be the scene of the climax. Harry and his bunch at one end of the Great Hall, Voldemort and his crew at the other end, the ghosts hanging about--I wonder if Sirius can come back as a ghost--and Snape and Draco in the middle waiting to declare themselves.
'Not Fade Away'
We're Literary 2: To Read Makes Our Speaking English Good
There's more to life than watching Buffy the Vampire Slayer! No. Really, there is! Honestly! Here's a place for Buffistas to come and discuss what it is they're reading, their favorite authors and poets. "Geez. Crack a book sometime."
I think Draco has pretty well declared himself. It's more a question of whether Voldy wants him.
As for Snape, there's one Big Question JKR almost has to answer in Book 7 -- why did Dumbledore trust him so implicitly? Until we have the answer to that, we have no idea where Snape is going to be. That may be the reason for Dumbledore's ghost to make an appearance.
But there's another question -- is Snape really the HBP? I remember somewhere that the HBP's Potions book was 50YO. That's Tom Riddle's day, not Snape's. Unless that's more misdirection because Snape could have bought it second-hand.
I'm guessing that the 50 year old Potions book was Snape's mother's. If his father was as abusive as the Pensieve memory in OotP indicates, it would make sense that he wouldn't want to spend too much money in the magical world, especially when Snape could just as well use his mother's schoolbooks.
Oooooh, good one Kathy! Also fits in perfectly with Hermione's repeated "how do you know the Prince was male?" motif.
I don't think we'll see any of our characters as ghosts, as Nick made it pretty clear that it's a kinda crappy afterlife.
Could anyone remind me which chapter of OotP has the bit with Snape's family life?
Hee. . .maybe the final chapter of HP7 will be called " Graduation Day ".
And really, it is rather likely that a giant snake will be involved somewhere in HP7.
I don't know that I'd go for giant , but the title could actually work. Oh!oh! And Snape could be eaten by the snake. Or bitten, whichever.
I think the Snake would be the one poisoned, in those circumstances.
