Nyssa, all I can say is that it leads to a lot of very interesting things, between the dominoes falling, and the way Bran responds to it.
I was expecting that, so it didn't upset me so much. The scene that bothered me more was the second-to-last one, where Daenerys was taken by Drogo so roughly.
I'm not going to be persnickety about being true to the book on most things, but I don't understand why they did it that way on the show when, in the book, he spent so much time being gentle with her, until she was totally seduced and told him she wanted him to...
The way they did it just seems to be needlessly inflammatory, since we already had people protesting this sort of thing. They're oversensitive, IMO, but why portray him as being a brute, when he really wasn't, afaicr.
