Nynaeve is wearing a yellow dress and a ki'sain... I think she's pretty self-explanatory.

I also looked for Moiraine's crystal but I couldn't see it, but I think that's what's meant to pass for a blue shawl, and that can leave only one conclusion. He also seems to have given her a few grey hairs, further strengthening the fact that its Moiraine, though it's factually incorrect.

Of course, the really exciting part is how this will all play out. I like to think that by that time all of the Forsaken are dead and these three are there to finish the job, though it still means facing HIM in the Pit of Doom. The two Sisters and Callandor can't be a coincidence... he's going to link again. I find it peculiar though because we were told that using both Powers would taint both Powers. I wonder what is different this time?
