Great non-canon line at the end from Siuan - "You are the water that turns the Wheel itself."
I wish we got to see more of new Mat in the trailer but I guess I can wait. What we got were snippets of some epic moments: the darkfriend social, Rand meeting with Siuan, Nynaeve's Accepted test, Rand v Turak, Heroes of the Horn (I think I see them on horseback @1:22 or so, may be a stretch, lol), and Aviendha (and Perrin!) in action v Whitecloaks.
I was already looking forward to the next season, especially sharing it with my show-only fan wife who loved season 1, and now we are both completely hyped for this second, atmospherically more ominous (I predict), season.
Of course, how did I not think of that! Thanks, I was thinking about Bors and some of the other characters that might have been there, but totally forgot Fain. Time to zoom in on that shot to see some more details, lol.
My latest thought is: what scenes shown in the trailer are more TDR than TGH? That scene near the end with Mat driving his spear into something (or someone) is immediately followed by an explosion at what looks like a castle or fortress - if those shots are actually connected, then this is very reminiscent of his activities near the end of TDR. But other than that, most every scene I recognized looked to be from TGH (which is not necessarily a bad thing, since I think TGH has more television-friendly moments in it throughout than TDR does).
