There is indeed so much flustering going on here, even if it goes ignored. Inigo still isn't quite over Tidus just wandering in on that, especially with his reaction to it all. Not to mention there's those initial words coming from Roland, which only seem to make Inigo freak out even more. He's not even sure anymore whether his brain is freaking out more about the embarrassment of a moment ago or the worry that he's disappointed Roland by not sticking to it for a minute. But--

"N-Not on purpose!" He whines, though goes silent after. Not that he's stretching like Roland or starting to do knee crunches like Tidus. Showoff. Inigo is more of a swordfighting kind of guy than a workout kind of guy, after all. Can't take the medieval mindset out of him. He's too unused to this whole thing to be getting into it the way the other two do.

Jumblie, seeming to sense his inner panic and subsequent sulking, is quick to jump out of Tidus's hair mid-crunch - sorry, pal! - before turning back into one full-sized higgledy mid-air and wiggling her way into his arms while he's still sitting there on his knees.

It doesn't stop him from being sulky, but at least encourages him enough to speak up again.

"Roland thinks the reason he can't handle the grav-con very well is that his mind isn't so used to his body being young."
