They really were right that you shouldn't overdo it, Tidus said. Right before using his power all over again.

Leaving Inigo behind in the middle of the diner by himself. At least people don't really seem weirded out by Tidus disappearing like that, since they do seem to assume it's just his power, but Inigo definitely did just make a scene and draw a lot of attention.

And Inigo already ordered food before this whole circus went down. He can't just leave without paying.

So he just sinks back down onto his seat, his face entirely red, and he drops his arms onto the table before burying his face against them.

Goodbye, cruel world. He'll just wait here for the food awkwardly by himself now. THANKS, TIDUS.
