The question of whether or not everything is okay with them individually is a long, long story that mostly involves a lot of 'not really's.

But the question about whether everything is okay between them as a unit is very aptly answered by Tidus. Enough so that Inigo only feels the need to add, half-awkwardly--

"Yes, it's just.. just a thing.. guys.. do."

He couldn't sound more uncertain about that if he tried, and Inigo gives Tidus a look that matches his half-awkward tone. He guesses he squabbles a lot with his guy friends back home too?! Usually about dumber things though. Which is saying a lot, considering how dumb this topic is already.

"So really, you're not intruding or interrupting anything! Handing out these things is the whole reason we're sitting here!"
