What does the Don do?

Just thought of something else...even though people know this one. But your Corneo Brother connection is valid because there is a character named Shinra on the same airship as Brother, let alone the same game. This obviously proves that FFX-2 and FFVII take place in the same universe, and some characters are reincarnated semi important NPCs.

Yup.

Not the theory but Square's statements in the Ultimania Omega prove that Final Fantasy VII and X have the same universe and that the idea was that Final Fantasy VII could be many, many years after Final Fantasy X. It was spoken of the idea that it could be, not that it really is that way. And yet they have the same universe like they said and I think that is very cool.

And Don Corneo is a playboy.
