I don’t know about the Harry horcrux theory. Something I thought about the other day, and of course I can’t remember it now, but it basically threw that theory aside for good.
See, one of the things I really like about JKR is her redemptive sense. I was actually thinking the other day that Neville might die, but after doing something more heroic than Harry. So like, years after the big battle, people still remember Harry, but it’s Neville that people are thanking and talking about. That’d be some poetic justice, I think, especially after all Neville’s been through. And not to mention that he and Harry were born on the same day and Voldemort made the choice to go after Harry.
I want to know really badly, but I also don’t want to know. I love the unfolding of a story, especially JKR’s.
