So Why Did Cid put Squall in Charge?

[maybee]

I always assumed Edea told him about meeting Future Squall so Cid ha Future Knowledge and knows it is literally Squall's destiny to fight the Sorceress and stuff.

This basically.

Also Edea would've known that the person who saves them in the future is a Gunblade wielder hence why Cid is so excited whenever there's a Gunblade expert. Cid says that Gunblades are hard to wield, so not only seeing somebody be good at the weapon is a amazing, but a expert ?!! Got to be the future hero.

And Seifer is later mind controlled to join Ulti in her command.
