I think both Kan-E and Merylwyb were being smart at the "celebration". They did seem like they wanted to do something to help the Scions (and the dialog with the GCs afterwards seems to reinforce that), but *knew* they either could not do anything meaningful or anything they did besides leave would only make things worse; if they did something, its highly likely they would have been arrested or killed right there, leaving their own homes in chaos. Even saying something could have made things really bad for them. Leaving ASAP was the best course of action.
What really surprised me about this part was...there really *was* a Dravanian attack going on at that point. I was so sure that those Temple Knights were just more traitors...and it turns out they really were there to get their commander back home.

I'm also wondering about this...I would expect Momodi to have some idea what could have been in that bottle. That she had no idea means one of a few things to me: the liquid was so rare that she couldn't recognize it (or...maybe wasn't a poison after all...), it wasn't actually the bottle used to hold the poison (which then leads to Alainne possibly being a traitor too, planting the bottle on you to be claimed to be the assassination weapon later.), or she was possibly in on this as well. Personally, I think she just really didn't know what was in it (or didn't really look, knowing you were *really* pressed for time now) and thought you'd see Alainne to ask her soon.
As an aside...I am suspicious of Tataru. Not quite the same "ok, the Crystal Braves are BAD news" suspicion of 2.3, but still. Things aren't adding up with her and it can't be just coincidence that she was the only one to get out of the Rising Stones alive at this point...

Also...why did we get arrested so...quietly? I'm sure we would have known that we wouldn't be just sitting in a gaol waiting to be rescued, we'd be executed as soon as possible to make sure we couldn't let the truth get out or get rescued and really oppose them. Even the random Crystal Brave in Mor Dhona is terrified of you...why couldn't we have fought until subdued? We just killed an enormous dragon...what is a few random soldiers to me?


As for the aid to Ishgard earlier...well, if I were being petitioned aid from someone who has completely ignored me when I really could have used their help only recently, besides all the other isolationist stuff they've been doing...I'd be reluctant to send more aid than a token force as well. When Merylwyb said her city comes first, then the alliance, then everyone else...she's being 100% right. They all need to look after their own first, then their friends, then everyone else. And with them being besieged by beastmen and Garleans even now, on top of their own individual issues...helping someone who refused to help you isn't a priority.
