there are some things in FFX that make me wonder.
Apparently, 10 years ago, Jecht went out to train and never came back. If that was the time when Jecht came to Spira how did he get there? If it was by riding Sin, someone has gotta see Sin coming, the massive hulk that he is. And while he was at it Sin would probably destroy Zanarkand as well. But why would Sin come to Zanarkand? And just happento pick up some blitzball player training in the sea?
And..
How come Sin did not infect Tidus and Auron with his "toxin"? Because it cant be a big lie because some guy in kilika is meant to be suffering from sins toxin.
Theories?
