Okay, In the near beginning of the game, Yuna does the Sending for all the people that died in the hands of Sin in Kilika. Lulu explains to Tidus that if the dead ones were not sent, then they became feins.
Later on, we learn that Auron was actually an Unsent, but, we don't see him as a fiend or trying to kill anyone. It gets even more confusing with Syemour. We kill him once, he dies, Yuna tries to send him, but fails, so Syemour is revived....HOW!? And WHY is he not a fiend?! (I picture Fiens as the monsters you fight in random battles)
Okay, then it gets even MORE confusing with Tidus himself! Since it is proven that a person that is not send comes back to life again (Seymour is proof. We kill him THREE FREAKING TIMES!!!!), so......Why couldn't Yuna just go: "Screw the sending of Tidus! I want Tidus back!" and there you go! Tidus comes back right then and there! (Since not doing the Sending on Seymour brought him back to life)
Oooooookaaaaaaaaaaaaaaay.......I do not get it.
Lulu says something about if people did not accept death, then they became feins, but if they DID, then they did not become fiends...But, Tidus's mom accepted death, she went to the Fareplane and no sending for her.
How did Seymour come back to life? I thought that if he did NOT accept death, then he'd become a monster like the ones from the Random Battles stuff.
As with the case of Auron, how come he's not a fiend? Did he accept death? If so, then why is he still there? Why did he not go to the Farplane the moment he died like Tidus's mother did?
Aaaaah! I just confused myself even MORE!
Help clearing this up, please!
