I won't really bring her back, despite me loving her character very much (I leveled her up more than Cloud) cause if she did not die, Cloud and the gang won't really have a reason to fight Sephiroth. If I designed the game, I'd probably integrate myself in it, an additional secret character, one that needs one hell of a guide to unlock. Yeah, that's what I always fantasize, in all FF games.
