Ohhh man just read the summary of the script. It sounds just like the book! I like the idea of the Others' scene being changed. I can see the scene fading from a group of Others circling Waymar Royce, closing in slowly with their swords held up high like in LOTR when the ringwraiths slowly close in on frodo. That scene gave me chills! I will have to brace myself though, I'm sure there will be some additions I will have to grit my teeth through. We can however just think of it as continuations of the book where GRRM didn't have time to talk about. I mean, it's got his stamp of approval on it right? As long as it's in the spirit of the character I think it'll be alright for me.
I will be bummed though if they completely do away with flashbacks. I want my Tower of Joy scene! But if they do add in the scene won't it give it away that she's dieing in childbirth?
