That gets the most out of Roland, the thought that regardless of how many worlds he ends up in now, the work for him never ends. That he'll never give up, even if it looks like he's settled in. He matches that smile too, shedding his defenses completely. Tidus feels like a kindred spirit in a way, a connection that Roland recognizes between the two of them, born from sorrow, similar where it counts.

He won't give up. Not now, not for the people of this train. For his new friends, or for the ones he's left behind. Not for his nation, or for his son who he'll never stop fighting for. Yeah, Tidus has got that right off the bat. Despair be damned.

Roland nudges him, matching that effort too. "Heh. What can I say? Old habits in old men don't just disappear overnight. Be scared if I stop."
