I was reading through an article which pointed out fan speculation that Shuyin is the original version of Tidus from the real Zanarkand:

What do you think of that?The idea goes that the Fayth, the creators Dream Zanarkand, didn't get everything 100% right. They probably vaguely remembered Shuyin and created a close-but-not-perfect version of him in the dream, and that clone ultimately became Tidus
