Time for the next part of the training? Maybe so, and Tidus nods his head to Taiki before swimming a little in front of Inigo, if with some space.

"'kay, open your eyes then, and gimme your hand, and Taiki too -- we'll get you swimming for real!"

The change of pace (of treading) should help, and maybe Tidus wants to do a little more too. A little more that isn't paddling in spot and being Inigo's cheerleader. More swimming, more swimming!

He'll even reach out a hand, waiting and ready to take one of Inigo's. Does he have to snatch it up, bro!?
