Rude, bro. Can Inigo help it that he's incredibly fond of Roland, huh? Sure, there are some jokes he could make about Roland that would make him feel terrible (as evidenced by the whole Meeting Incident, really), but this isn't anything that could be seen as personally insulting towards Roland. It's just a joke about him having to clean up the watery mess that Gibbs would surely leave behind, knowing how that higgledy usually gets to work.

But before he can even continue the joke, there's instead that wall suddenly almost being shoved into Tidus's face. It's so comical - something out of a slapstick movie, if Inigo would know what those are - that he lets out a 'pfft' kind of half-choked laugh before concern takes over instead.

"Are you okay?" Got to make sure! Even if that looked funny, it's not like Inigo wants his bro to be hurt. Although he still can't help slipping in a small joke-- "Maybe Roland heard you somewhere."

And he's the evil overlord behind the machinations of these walls! Punishing Tidus for his Roland crimes.
