now i didn't say everything, i said a lot of things, still there's some unanswered questions and inconsistancies they may address later but that's up to S-E if they wanna straighten up those few things left undone / unanswered / unexplained, but it is a fantasy world after all that continues to grow and evolve, and in their world there may be a direct link to the soul and body, being one thing and not something seperate, notice how they just fade away like Jedi when they die, except for Aerith, but she's the exception to most of their rules...
