It would be nice if she could become one of Kurome's dolls. That would add a deeper layer to the Akame v Kurome fight.Take a guess
Though, in the anime they just sat around doing nothing :|
I wonder what's gonna happen to Mine though. I doubt she'll be left in a coma, so either she dies or wakes up to play some other role.
But since her teigu is destroyed i don't know about that.
