What did Tidus want when he died? A multiple of outcomes, the biggest that it wouldn't happen. That he'd live despite what he did, but if he couldn't have that, that it was quick, pain - that he didn't even notice, or have to confront the others about it. Going over and over and over every little possibility, but never letting them form; and then always deciding that whatever it was, would come. That was it, he'd have to face it no matter what - because not would be the death of people he loved. The death of Yuna. And Zanarkand wasn't a life he could ever go back to with, if Sin still existed.

(Or without it.)

He hums, a non-committal sound, a noise as his thoughts drift. Death isn't what he talks about often; not his own death. Now isn't really the time for it either, but he lets out a breath, a sigh before he speaks.

"Well, you've lived a long time." He's noticed that roster age, guy. "However long we're stuck here can't be a lot for you."

It'll be over quicker, is what he means, but maybe Elidibus's personality will make it easier to deal with than it has been for Tidus.
