This is a pretty minor theory, but it may provide a small clue to the whereabouts of Myrelle and companies party to the black tower. In TSR, Min had a viewing of 'an apple-cheeked Accepted' where "bars floated in front of her face like a cage."

The accepted in this viewing was never named, and until now, I don't think we have seen a specific instance of an accepted being imprisoned. Theodrin has been described as having a round apple-cheeked face at least once. Theordin was also an Accepted at the time of Min's viewing, and there weren't tons of Accepted walking around in the WT then.

I believe Min's viewing may have had to do with Theodrin being imprisoned in the future. This would dovetail with her current expedition to the BT and the fact that she has not yet returned.

As Deadsy has already pointed out, Min also had a viewing about Faolain: "it does not seem fair that a nasty person should have good things coming." From this perspective, Myrelle, Nisao, Faolain, and Theodrin may not be turned yet.

Unless her good thing was being raised to Aes Sedai, then Faolain will most likely be rescued from her current debacle.
