lets see.... if i remember it correctly.. there was a brief explanation of what farplane can do, that people can see images of people that they want to see inside the farplane. And because tidus and everything in his memory in DZ was from a fayth's dream, it made it possible for tidus to see his mother images, because the source of this images comes from a fayth in spira. (...well that's what i think.....)
Yeah I remember all of that about the Farplane, but what I'm curious about is at the end, it shows Tidus with Auron, Braska and Jecht. I'm curious if since they became more than just dreams that they ended up in the Farplane and since Tidus's mother was a dream of the fayth as well but not really touched by Sin in the way Jecht and Tidus were, if she stayed on the Farplane or if she faded out when the fayth stopped dreaming and did not remain on the Farplane?
