"Mmm... I don't know." Even as Seto describes it that way, thinking about it, even as a roadtrip kind of sense. After everything...

"I think I'm tired of adventures." Sightseeing or whatever; even if he had the chance to do all that. "I mean, all the different worlds out there is kind of cool, but being around a town and having a life? I really miss that. I don't belong anywhere out here."

No home, no life. Maybe that's what made Seto and him different; a guy who could take people on as family, but Tidus, nothing about his time on a train felt like a life. A purpose. Nothing other than getting people back home, and that was it. ... but even if it was just a dream, having stability again, something close to normal - it was a nice one.
