Tidus catches the off-guard expression, brief as it is, the way it's answered with boasting. He doesn't really question it, the way Inigo accepts it not really bothersome. Though he does scoff, throwing him a half-judging (but not really sincere) look.

"I have, 'cause we made her." Because when Tidus thinks about it, sure--he knows a hero type alright. "Giving her everything for other people, putting herself before others? That's where people like me come in!" Dropping any hint of a lecture from his tone, Tidus gives the back of Inigo's shoulder a slap.

"Remember, you're part of a team! You're not the only hero out there--and I know you wouldn't tell anyone else not to take a rest. Trust in us to have your back!"

Well, maybe it wasn't that much an end to his considerate nagging. But it's not Tidus's fault Inigo is like that!
