potentialities

It does seem a tad unlikely that the real JKR would hope people don't figure out the ending, but then go ahead and give clues about it anyhow.  So I'd bet most of the stuff she says consists of red herrings... If that's really her, I bet she just starts talking all sorts of shit in chatrooms about Sirius Black not being dead or whatever, to freak people out in order to amuse herself after a long day of rewriting chapters or something.  I'd sure get a kick out of it, if I were in her shoes.

Perhaps not all of it is total B.S. (the significance of the name "Remus" seems very Rowling) but... all right, to be frank I just couldn't deal with it if Ron were evil... *sob*  He's been my man ever since that chess game in Book 1 where he's gonna sacrifice himself to the queen and they're all "no Ron don't do it" and he's all "well that's chess!"  Or something.
