Sorry if already discussed but wasn't there a sample chapter from Winds of Winter involving Stannis and Theon? The only one I can find now is Arianne. Did it get taken down/where can I find it?
I'm pretty sure he simply read it out loud to all the people at Comic Con and there are just a bunch of people who transcribed that. Although I could be wrong.
It was up on the same page where you now see the Arianne chapter... You'll need to scour the web to find it.
