What the fruck just happened!
I think a lot of people who did not read the books are going to have a big problem with how Season 3 ends.
In the book, then the events of tonight's episode occur, it is a "holy **** I can't believe the author just did that" moment. It was still shocking to me tonight, and I had read the books. If I was watching on TV, and hadn't read the books, I would be thinking to myself right now: "I just invested 3 years into this incredibly complex swords and sorcerers TV show, and the mofo writers just did that to me? Forget them", and move on to a show that doesn't try to punch me in the face.
There are certain aspects of the plot that just do not translate well from the books to TV, and this is one of them. I think the show producers have done a very good job of emphasizing a lot of over characters and plotlines so that it doesn't seem like they lit the entire plotline on fire tonight. Just most of it.
