The swirling cloud of tiny fish surprise a laugh out of him, quick short bursts of sounds that tangle up in their silvery scales as they dart past him. He swirls in the water, watching them gather and break apart once more when they get close to the rocks, as much of an unit as they are each their own individuals. It's fascinating to see.

Jingyi's comment gets his attention, and Esteban turns bright eyes to his companion from underneath his mask.

"Oh! Tidus loves fish though!" There's an idea! "We could catch some for him!"

Nevermind that he has no idea which fish among these is edible. It's not like it matters, does it? Surely, they can figure it out by pure luck? Either way, it gets the redhead to grin widely as he swims up to grasp at a passing darter, but the movement in the water is not quite as easy as he'd hoped, and the silver-finned fish dashes away without much of a hassle.

They're clearly going to have to work together if they want to catch them.

"I'll scare them your way?" the half-elf offers, still excited at the prospect, even if it's just because he might be able to do a favour for the blond. He'd like that; he doubts that Tidus would care either way, but it's... it's a tiny gift he can offer. He can try to offer at the very least.
