Did you let her boobs fully grow out?The only other quest I've held off on is Natasha (who I think might have a bug because even if you stop the corruption, she still says she switched to isha which shouldn't happen). I reported that so if it is fixed, I'll probably go through the route of not completely corrupting her.
If I remember correctly in the wt if her transformation has been completed then she’ll stay devoted to Isha regardless of you try to change her back or not.
