Man, I didn't expect the red wedding at all, although reading it a second time, i could kinda see it coming. there were a few warning signs. But the thing I think I like best about Martin is that when his characters speculate, they somehow seem to be asking the same questions I am. Like, when I'm worried about a particular thing, a few pages later, someone starts talking about it. Oh, and if we are going to take bets on the starks, I personally think that Jon is going to marry Daenreyes. It doesnt make any sense at all, but I hope it happens. And I'm also hoping that either Arya, Tyrion, or both become some of Dany's companions. Tyrion is just the coolest character in the series, and arya's starting to grow on me (i liked her better when she was getting trained by Syrio).
But about the champion of light. Regardless of who it is, they better stab Lightbringer throuh Mellissandre's chest. That would be almost as perfect a moment as Tywin's death.
