10 Questions on the FFX-2 Story

[Renmiri]

He survived after they were shot and was locked away. He soon passed away due to depression and hatred.

But then why he tells Yuna (first time they meet on the Farplane, he thinks she is Lenne) that they dissapeared together ?
Shuyin: It is me, Shuyin. I've waited so long, Lenne.
Yuna: But I'm not Lenne.
Shuyin: Lenne. We disappeared together, but when I awoke, I was alone. I looked for you for so long. While I wandered, I realized something....

Leene's died and her soul crystallized into a dressphere. If she too survived, she will have been locked up like Shuyin.

Sounds true

Shuyin and Lenne was shot in Bevelle.
Leene died and Shuyin was locked away until later he died too.
They did not became pyrefiles in farplane.
Leene's soul crystallized into the songtress dressphere.
Shuyin's soul was trapped in the Den of Woe and his hatred grew.
He possessed Nooj when they came along.
He soon switched to Baralai during the game and controlled Vegnagun.
The rest is clear.

Hmmm.. Makes a lot of sense. I guess we could read Shuyin's words We disappeared together, but when I awoke, I was alone. in a way that when he awoke in the GAOL jail he was alone...
