Excuse you, mister grumpypants will grump just as much as he wants here!! Even if he is getting some touches from Taiki right now. The one thing he's polite enough to do is not start eating ahead of everyone else, instead waiting to make sure Taiki eats first. That boy needs it right now.

... well, okay, maybe he can do two polite things by not totally ignoring Tidus's question.

"There's only Naga and Grima where I'm from." And since they're very present and physical, it'd be hard for there to be some sort of god they've overlooked. "Does that mean other worlds have gods for very specific things?"

It's a pretty baffling idea to him. Maybe thinking about this hard enough will slowly replace his grump thoughts with actual thinky thoughts.
