All of 'em?
But, do you mean you passed the part where Rand, Loial, and Hurin went through? Or, where Rand transports Verin & co. to Toman Head?
If the first, I'd like to see the battle between Hawkwing and the Trollocs that led to that world.
If the latter, I'd really enjoy seeing the world where Rand stayed in Emond's Field and married Egwene, not because of any love for Egwene, but because I'd have liked to see how Rand and Tam's relationship would have grown.
