I think this is one of the issues where the Aiel get caught flat-footed because they cannot conceive of someone failing to act appropriately and fulfil their toh. The way they are constantly being surprised by Couladin or Sevanna's perfidy. No Aiel woman would refuse to do what must be done to protect her unborn child, so there is no enforcement plan or even policy. They say "So, Shaiel, you must put aside the spear so long as you carry a child." Shaiel says "No," and they're like "what now?" The Maidens might intervene, or they might not, recalling the various times Rand clashes with them over the issue of personal responsibility and how people cannot dictate how others act. All the comments and arguments that would have shamed a born Aiel Maiden into compliance would roll off Shaiel, because ji'e'toh is just something she picked up a few years ago, rather than take in with her mother's milk. And overall, maybe this is a thing for the battle-leader, but the combination of his infatuation with Shaiel and the general notion in the setting that men's opinions on women's matters are not welcome, thank you very much, mean that nothing gets done, because when you get right down to it, pregnancy is a problem with an inherently limited shelf-life. Just like I'd bet that at least some people were willing to let her try to join the Maidens because they expected her failure to be inevitable, I'd guess that some people figured Shaiel would crap out eventually, and the rigors of her condition would mandate her taking a reduced role, and then once there was an actual baby in hand, of course she'll see reason.
Hardly looks like she's related to a guy as drop-dead gorgeous as Galad is supposed to be, or a man whom three 10s are will to settle for a partial share of.

I saw that. He also had an issue of Nynaeve leading with her knife, pointing out that there are lots of women in the series who would do that, so what separates Nynaeve from Egwene or Aviendha? And he also noted that Healing is Nynaeve's central aspect, not violence.
Good idea.

They've never exactly had that. It could survive in a limited environment like Emond's Field, where the proper way to do things or handle whatever situations that come up is pretty clear-cut. But they have a fight over the first thing that comes up out of the ordinary, namely her sudden career aspirations. Egwene initiated the relationship without consulting him, going over his head to get the establishment to sanction it and protect her relationship position, without any indication of concern or respect for his feelings on the matter. And that's all the time with him. She cares about him, but in an unbalanced or uneven way, not as a partner in anything. You can see one of them being in charge in a relationship or on an issue, but you can't image them being partners or a team.
If all this is the case, the official position of the show will be "not Siuan's fault and this is absolutely no reason for anyone to doubt her on anything going forward, and Nynaeve is being a stubborn, contrarian bitch for questioning her."

Another possibility going forward is that Mat somehow follows Fain via dagger connections or whatever, and saves them from him. Or he gets dragged back to the Tower by the Reds and his Book 3 plot will take off from there.

In the books, I have to ask, where does Moiraine ever even HAVE a downfall? The closest you could come would be her swearing to Rand or going to the Finns, but those were entirely her own actions and choices that brought her there. No ally, superior or enemy did it to her. So we're talking major plot rearrangements ahead.
