Now that I think on it. It just makes me think of FF10. I hated that one of all the FFs. But the story with Tidus, never existing, and thus you know he's not coming back but get to know him anyway.

Or better comparison. Kingdom Hearts, the Nobodies, characters like Roxas and his friends you get to know, knowing they have no future.

Both storylines they somehow brought them back though. Tidus in 10-2, and the Nobodies in KH3 (somewhat).

So given Square's usual shenanigans with the stuff and given that the writer of KH is helping write the current. MAYBE THEY WILL BE REBORN. Maybe that's going to be our new companions.

(I can hope and dream)
