¿quien en diablos es el HBP?

Just an update, but I've completely altered my previous specs about the Half-Blood Prince. I haven't changed my mind on who I think he is, but I just added a bunch of background spec and book 6 predictions. Also threw Godric Gryffindor's name/history into the mix.

( Since I don't want this to be a totally pointless post... the HP 100 meme )
