I always liked how this showed the trait in all the Unsent, where they are really stuck in the same mindset they were in when they died. Sure Auron is traveling along with the group, but that's only motivated by the promise he's trying to for-full. All his actions are based on his promises, and everything else he tries to rush past, as if he can't even comprehend, or refuses to arch-knowledge them as anything of import.
Seymour who can't see past his desire to become the next Sin. While having some character traits back when he was alive, be becomes full "death" focused after being unsent.
Yunalesca who adamantly believes her way is the only way, not even comprehending there might be another solution.
Maester Maika being the same, thinking that their 1000 years of preforming the same tactic over and over is the only solution, the very idea of defeating sin being impossible in their mind. I don't think its a deal of being stubborn, but more that unsent are unable to learn new concepts. Whatever spark it is that drives the living, they no longer have that, and can only remain a shadow of their former self. A reflection from an old photograph if you may.
I feel that even if Maika would have stuck around to see Sin being defeated, he would have been unable to even comprehend it, to actually realize what had happened.
No one ever mentions the pure heartbreak and pride on Cid’s face when he keeps his back to her.
Some consider it rude, I look at a man too proud of his own self to show that he’s so proud of his niece and how happy he is she’s still alive, maybe even seeing some of his sister in her.
Is it just me or is FFX story literally the exact same thing as The Matrix? And I mean that as a compliment. It's just beautiful. Even the concept of the Final Aeon and how YuYevon uses it to continue the cycle of Sin is exactly similar to the concept of The One and how The Architect/machines use it to continue the cycle of reloading The Matrix. It's absolutely beautiful
