Ava
Some of you are disappointed in what happened with Ava so I think I should clear some things up.
Akio's lovers were never in any danger even with Ava herself saying so.
I perhaps haven't shown this enough but she doesn't even know her own feelings.
She cares deeply for her family (which includes her fellow wives and Akio's lovers) so make no mistake if her intention didn't play out the way she thought Eden would have disappeared immediately.
I should also make this clear. Akio is inevitable. There is not a single thing anyone can do that would stop him from reaching his desired outcome.
Still, perhaps I made a mistake without how her character is presented. I'm going to edit the chap a bit so that Ava is prepared to step in if necessary.
