The relation is this. Horible mistake that was ff10 and ff10-2 tryed to tie it'self into the gloryus golden god like thing that is ff7 by make that disgusting mako refrince. had I ben on that air ship when Shinra made that Commeent i would have swiftly and thoughtlessly tossed the little blaspimer overbord, then listened for the heart warming SPLAT that would put an end to his evil ways. IMO it was the creaters of ff 10 and 10-2 trying to hook hardcore ff7 fans and it failed. even sugesting that spira has anything to do with ummm what ever the world is called in ff7 is eeeeeeeeevil.
