Oh I thought it was Thom too, I figured it was Thom giving Rand and Mat a crash course in What's Aes Sedai All About. That was the bit of trailer that provoked me into telling Moiraine to go get it girl. :lol
Is that Thom Merrilin near the beginning? Ooh he's going to be a SNACK, isn't he?
I'm SO sad about Mat's recasting. Every time Barney says "You've fully lost your mind" I've involuntarily burst into a smile, and I've watched the trailer four times now.
