"Well, you should apply some of that into your dancing! I want this kid to live, so I'm going to do this - I want to dance, so I'm going to dance!"

It's the same old tune Tidus has always sang when it comes to Inigo's confidence. Though really, when it comes to this-

"But you shouldn't listen to Reno anyway. What I was saying was, that's one guy out of how many on a train? I told Taiki anyway we should hang out together more in the music car," he goes on, just bringing that up because he can. "And he agreed, so now you have to dance more: because we said you should."

There. Brilliant logic.
