All the even FF's are connected.

The Mist is actually the fayth from FFX, it allows us to see those we lost. When it concentrates in high density, it can take on other functions, all having to do with spirits, some of which spawning directly from the Mist.

Reks is a soldier who came out of nowher during the assault on Nalbina. Basch didn't recognize him, he wasn't from any unit, the Mist surrounding the fortress created him spontaneously to begin the great quest, beginning with witnessing the King's murder. He also claimed to have a brother named Vaan. He and Vaan may have been real people once. However, they are memories. When Reks was injured and would not be able to continue the journey to save the world, his likeness/duty was passed on to a newly generated entity, the brother Reks thought that he had.

The mist you cannot see infiltrated the minds of Penelo, Kytes and Fido. They all believed they grew up with a young boy named Vaan. This occurrence of the mist, peoples memories, generating a hero, occurs once every 10,000 years, and thus, ladies and gentlemen, I conclude:








Vaan = Tidus.

Thank you.
