[spoilers below, obviously]
unfortunately, didn't get a chance to watch this in real time, so i saw on fb where some people were freaking out and saying things like red wedding (which c'mon can only really mean one thing) and my buddy had casually mentioned to me months ago that Robb dies in the book that this season is based on, so it was pretty easy to put 2 and 2 together, which kinda sucked. would have loved to have just been completely hit by this one. shucks, oh well, that's mostly my own fault.
still, very powerful and definitely a crazy ending. so much throat slitting.
One small difference between the book and the show, in the books Robb left his wife at home and didn't bring her to the wedding because he didn't want to disrespect the Freys, in the show she came to the wedding and it turned out being a hell of a bad decision.
How great is this show? Seems awesome..
That ending was crazy!
