I think we're looking at for leaving:

Miyu: Definitely leaving.

Beast: For a moment was gonna leave with Miyu, but then seemed to instead want to team up with Fran.

Lillian: Considering leaving if enough people do.

Gelgath: Considering leaving if enough people do.

Abigail and Bonesword: Seem to be under the impression that they will somehow be unwelcome/will end up somewhere horrible. This really is the get out of jail free card.. But ok. I mean, Miyu could even do mental networking to let them both know they can both take it and know the other person is also taking the deal.

I really wonder if Zak would care the slightest about the war, and whether he'd wanna skip out. I think he's already had enough of Harley. Kinda hoping he does cause I liked Miyu and Zac's conversation, short as it was.
