HPotter Book 7
Okay, so how about this?
"'No!' roared Snape. . . (pg 603). . .'Potter belongs to the Dark Lord'"
What if Harry is the Horcrux? He'd be the "something Gryffindor."
Perhaps he has part of the soul of Voldemort, hence his ability to read Voldemort's moods? Very old, classic ending (most recently seen in The Matrix closing), where Harry must sacrifice himself in order to destroy the other. Only in success does Voldemort fail.
This advances the strong love/sacrifice theme begun with Lily and strengthened by Dumbledore (central theme of the series?).
Isn't the end of Book 6 a furthering of severing of relationships for Harry (Dumbledore, Ginny, and Hogwarts itself), a recurring pattern in Harry's life, which foreshadows greater solitude soon? Won't Hermione and Ron name their first child Harry in memorium? Will Ginny really become a Weird Sister who plays Quidditch for England?
Hmmmm....
Of course, one flaw is that moldy Voldy wouldn't have tried killing Harry in the cemetary at the end of #4 (the best one, btw). But what if that's why Voldemort needed Harry's blood especially, to reclaim part of his own soul? To access one of the Horcruxes?
Well, there you have it. Read it again soon, before Rowling's intellectual property lawyers serve me with a cease and desist order. . .
