They really weren't going to do this proper good-bye thing, were they? But Tidus has given a few farewells as it is, and he's not going to chase people for more. Maybe it's a good excuse too, to get distracted - and not have to help a bunch of awkward and sad "see yas".

"Okaaay, okay." But he'll still make it sound like he's being put upon by Esteban's insistence. Just, nevermind the smile on his face. "Quick version is, you have two teams and one ball! Your team has to get the ball and put it in the goal on the other team's side. Everyone's moving around in the middle trying to get the ball-" and he waves both his hands to mimic the fluster and movement of the players. "-and there's always someone at the goal to protect it, or people in the middle who're gonna try and stop a shot! And don't forget the important part that this is all underwater!"

Because everyone makes a big deal about the water part, so, you know. Emphasis on the underwater.

"You have different ways you can set up your team, who's gonna stick on which side of the field, who's the one you want shooting the ball, but that's for me to show later. But maybe you've heard of a ball game like that! I know the train's got some like it in the sports gym."
