On sidenote, I dont get why get so upset about Robb. I guess some people just like that heroic-noble-boyscout vibe. Robb surpassed even his father in terms of acting like a complete idiot because of his egocentric sense of honor. He was utterly incompetent in every way as ruler except winning battles, his rebellion was attempting to split the kingdom and cause even more instability and if all that wasn't enough, he elected to satisfy his dick instead of keeping his word. Best leader ever. He would make a terrible king, people can now pretty much rejoice that the rabid warmonger is dead and a proper ruler (Tywin) can bring peace and stability. /nerdsprache off
