So, spoiler-free, but NOTHING below is verbatim what was said, its all from memory:

Nobody asked about Asmodean. (I thought that was funny.)

Q: Someone asked if Brandon writes the books in a jumping-around fashion or if he writes one character's story at a time, and then they get spliced together in editing.

A: Brandon says he does write one character at a time, because you have to try to think like that character and feel like the character. He says to be able to write someone, it's like uploading all the information about the character, and then using it until you're done. Then you wipe your hard drive and download the next character. He goes on to say that the editing and splicing is almost entirely Harriet, but when Brandon feels strongly about something, he insists. (Brandon said one such point was at the beginning of ToM, a cliffhanger ending to a chapter about Mat...) Harriet took the mic at this point and said that if Brandon puts his foot down, then that's it, and he gets his way. They laugh.

Q: Somebody asked if we will get to see an Aiel Wise One as a damane. (Pronounced DAH-mah-nay)

A: RAFO.

Q: Somebody asked who his least favorite character is to write.

A: He said it was probably Gawyn. He said when you write a character, you try to think like them, and Gawyn is so frustrated with his situation that Brandon would get frustrated writing him. He asked Harriet to tell a funny story about Jim.

Harriet: Jim would get into his character's so much that sometimes when he came to dinner I could tell who he had been writing. For example he would come in kinda hunched and slinking around near the walls and I would say "Have you been writing Padan Fain?" (Harriet and Brandon laugh)

Q: Somebody asked who his favorite character is to write.

A: He says that he enjoys a lot of them, but that writing Padan Fain is very enjoyable, because by this point in the story he is just bonkers (his word) so it's fun to write such an insane perspective. He said specifically, the excerpt Harriet read aloud was pretty much his favorite to write. (see above)

Q: Someone asked him if he would do the evil Forsaken laugh he was purported to have done at some earlier time.

A: Brandon does an evil Mwa-ha-ha MWa-HA-HA laugh (hilarious), and everybody cheers. Then Brandon turns to the guy filming the event and says, "Oh no, you're getting this on film" (laughs) "Any chance we can edit that out?" (joking. Camera man shakes his head no. Brandon laughs)

Q: A guy named Louis asked what's going to happen to Bela. (He pronounces it like "Bella".)

A: Harriet corrects his pronunciation (it's more like BAIL-a) and then, looking mysterious, asks "Would you believe that Bela is the Dark One?" (everybody laughs)
