Tidus and Shuyin: An Analysis

[Squall of SeeD]

I've been reading trough this and I started thinking of something.

The Aeons tell us that The Shujin we meet is not the real Shujin, and that Shujin died long ago. It's his feeling that are preserved, his feelings were so strong that they took form.

Well, he's clearly established as an Unsent. It's just that his feelings of hate and despair consumed him, but that's not all that there is to him, as is made evident by Lenne's love soothing him.

And it is possible in my oppinion that Tidus is a reincarnation of Shujin.

For the faith to dream up the citizens of Zanarkand, they need souls. Can the Faith create souls to insert into the people of dream Zanarkand? I'm not sure, but maybe this is what you meant about recycling souls. This does not seem impossible as it seems that the faith can manipulate pyreflies to their wishes.

Technically, it's Yu Yevon and other Summoners that manipulate Pyreflies, but I see the point you're trying to make. In any event, the problem with this theory is that Shuyin and Tidus were present in Spira at the same time, leaving it rather unlikely that Tidus could in any way be a reincarnation of him. While it may be possible that something of his memories were imprinted upon the Pyreflies used to compose Tidus, we're left with the question of how those Pyreflies got all the way to Dream Zanarkand, whereever it may be in Spira.

It's not impossible. It's just so hokey and unelaborated within the story itself as to leave us without a simple means of explaining it.
