Jecht tried not to think about the community. Sure, he'd met wonderful people -- Terra, Jack, Cross -- and promptly lost them all. Yeah, it was swell knowing exactly what was going to happen to him. Watching the ruined wreck of the man he loved might possibly have very strong feelings for and knowing that was coming for him. Having Cefca out of reach most of the time, too far to help. The community was awesome.
If Tidus were alive and well and still doing a shitty job at his own pilgrimage, Jecht would probably, very honestly, be drunk right now. But Tidus wasn't alive. Chalk that up to one more great community experience: watching your kid die before you did. And before he'd gone, Jecht had made him a promise. No more drinking. He had his act together this time and he was going to keep it that way.
So instead of "liberating" Auron's sake jug and making off for some quiet time (which was still the best-sounding idea he'd had in months, counting the time he'd lived twice-over now) he got a worldhop and snuck his way into Guadosalam. He wasn't really sure what he was doing. This was a long shot, he wasn't stupid, but it was the last one he had. He wasn't even sure what would happen if he crossed the bridge to the farplane, but -- hey, look at that, still corporeal. Ignoring the dirty looks from the couple next to him (fuck you, he's a legendary guardian, he does what he wants) he raised his fingers to his lips and let out a piercing whistle.
