Okay, I'm going to explain something here. First that shoulda been in a spoiler but I doubt anyone here didn't know about Arieth dying. Second, in Final Fantasy when you "die" you take so many wounds that you cannot continue fighting. That's why in some it's called swooning. The "Life" spell and "Pheonix Down" Item, heals your great injuries and brings you back to conciousness. Since she had her heart impaled, I don't think she was just unconcious... Now if it had been Dungeons and Dragons, that would be a different story. But it's not.
