She already did before, she doing this would mean all that build up of her being devasted was for nothing. So it would be better to scrap out all of that.
Makes zero sense.
The thing now, that would make sense is Morgane, since she's obsessed with Avarand clearly TOO MUCH submissive and dump, to be explored by Avar for his company, so this would mean sharing.
And Elaine getting angry with Avar keeping Morgane close and not completely kicking Morg for her, and cheating on him, so the netorare tag would continue.
Anything other than that, IMO, would completely break all the goodwriting the dev did on Elaine, Avar and Morgane characters and would be a shame.
I'm clearly not playing the same game you are, Morganne is the perfect personification of the obsessive girlfriend, even if she's dumb and horny, so she ended up doing sexual stuff with others, she's the kind of girl that live for Avar, he's the sole reason she's alive. This is clear since the start.
This kind of obsessive relationship, means Avar can ask ANYTHING from her, she'll do, before or now.
Zero yandere.
