After I beat the game, for some reason she re-appeared in my list of revivals. Be aware that if you revive her without using the f12 technique you will be reset back to the start of Biscotti… along with all revivals after that storywise getting locked up.
So they have to be released again. oh and also if you don’t use the f12 you won’t get Klehss again, so it’s like double bad.
