No, because he (it?) was there when we saw her at the Ark. But if FUG is supposed to be part of the representation on that panel, it would make more sense to use characters that we principally identify with the group. Someone like Karaka, Jinsung or Yu Han Sung. Not Rachel and Akryung.
So, Akryung isn't solidly FUG to you?
I'd argue the response simply is those they (Rev) have networked with (in FUG) vs not. Goruro made it clear that this is the first official meeting by HJ and himself, whereas they only spoke over the pocket or through other intermediaries before. FUG and Rev have not commonly rubbed elbows though they think increasingly the same.
Captain also makes no sense. Is the the Captain... of Rev?
How do Captain/Rachel/Akryung fit the qualifier for Rev? That qualifier was explained as those upset in the 10GF households. That doesn't seem to apply to any of those three.
IMO, Akryung still being with Rachel means the latter is still working as a FUG agent, despite her networking with Bellarir.
After all, HJ/Cha are networking similarly (now) with Rev. Rachel, the slime that she is, just started before the likes of HJ.
Obviously, if the two groups are becoming one - as explained - they will have to increasingly work side-by-side.
