he's going to pop out a huge army, totally blindside the Light, and we're all going to be like oh... that's what he was up to... pushing the Seanchan Return, inciting the Tower to split, all the wars, etc (basically masterminding the three-way with Semi and Messi)

That's my theory and I'm sticking to it, although it will be quite embarrassing if it turns out that he's actually just been concentrating on Mayene this whole time or something. But yeah he's Demandred and he can do whatever he wants cuz he's just that cool. He can probably beat that massive Borderlander army with a pack of poodles because he's just that good of a general.
