Oh wow I was in shock watching that. That was so well done, at first I thought killing Robb's wife was going to be the payback, but nope, it carried on. Loved Arya running in to help, and the Hound knocking her out and dragging her away. I like their little double team, although it'll be interesting to see what the Hound does now since there's no-one to pay him for her.
I'm glad Brann at least got to see Jon Snow even if there hasn't been a reunion yet (I hope at least part of the family gets to reunite, I mean I love that it's dark and tragic but I'd like a little sweetness sprinkled in here and there). I also wonder how long it will take for word to reach Sansa.
