Honestly my biggest issue with Endwalker is how Fourchenault just disowns his friggin' kids in the lead-up and then everything is just kinda fine by the end of the Sharlayan part like he didn't just DISOWN HIS KIDS and also the whole "Sharlayan prejudice against literally everyone" is never really addressed either.
Unironically, if I get the time, I kinda want to write a one-shot where Fourchenault is the representative sent to talk about the whole "final days plan" to Ishgard. Except the WoL already told Aymeric about what happened and Aymeric is Upset on Alphinaud's behalf.
And so Aymeric is just increasingly passive-aggressive towards Fourchenault, who is kinda confused but assumes that it has to do with New Sharlayan just buggering off at the first sign of trouble, until Aymeric casually drops that the WoL ended the thousand-year war with the dragons, and oh, he couldn't have done it without a certain Alphinaud Leveilleur's help, so of course Ishgard is going to stand behind whatever their plan might be. He's seen them pull off the impossible before. Oh, and he's reached out to the other city-states and while they're willing to hear him out for the sake of their people, they're Not Happy in general with Sharlayan and are far more willing to side with the Scions, who have done far more to help them with their problems.
And Fourchenault realizes that maybe they've Fucked Up. And also he's disowned his son who is actually kind of a major diplomat to like... the entirety of Eorzea. Whoops.
(And it would loop around nicely with the scene where Alphinaud is calling in all the friends they've made and they make more progress on the starship in days than Sharlayan has made in weeks.)
