I wasn't expecting them to kill Talisa, especially in that way :eek
They did an amazing job with the the whole Red Wedding. In ways I think the episode last night had a better impact than the books in many ways
The scene with Catelyn pleading to Frey and asking Robb to just get up a walk out was superbly acted and the whole thing was just gut wrenching even if you knew what was going to happen.
Supposedly they originally wanted Martin to write that episode, but he said he it was tough for him when writing those book chapters and that he would rather not revisit it again.
Walder Frey...heh...one of the most hated characters in Westeros
Well, there was ONE thing about the Red Wedding that I think wasn't accurate. In the TV version, Rob's wife was there and was murdered first. I THOUGHT she wasn't there and elsewhere, and there was question as to whether or not she was pregnant and would have a child that could have a claim to the North. This clearly finished up that plot thread.
Yeah she wasn't there. There's been a few unanswered questions that they answered in the TV show this season. So we know for sure she was pregnant now, and at the same time I guess it apparently makes no difference to the plot line in the future books. Among some of the other minor mysteries they cleared up for book readers was who ordered Ser Mandon to kill Tyrion.
Also they didn't go too much into the whole thing of Catelyn's paranoia before hand of Frey doing something and how she kept harping on Robb to make sure to ask for bread and salt to secure guest rights
Also while not that important, Catelyn killed Jingebell (Aegon) not one of Frey's brides. So they pretty much eliminated all the fools/half-wits at this point
One other notable difference was the band. Supposedly they sounded terrible and the music was just a loud cacaphony since most of the band were actually soldiers IIRC
In the books, when Dany went to the House of the Undying she had many visions which foretold events to come, especially after going back and reading the chapter. One of them was of the Red Wedding. She saw a multitude of slaughtered feasters, above whom sits a dead king with the head of a wolf. A few remain to be uncovered
One of her other visions is what comes about in the next episode
