"Hey, that's a great amount!" So much even, it's distracted Tidus from the door and that whole 'entering' thing for a moment as he looks at her. "Is that normal where you're from? The game's blitzball -- all the best players know how to hold their breath that long! You heard it?"

Maybe? Maybe? It'd make his day, and it's the closest possibility he's gotten that someone else might know the game -- just because of a decent lung capacity (look, he doesn't get a lot of potential 'maybes' with this, ok). But he'll remember about that door now, lead the woman with him through the passage to the next carriage, the pair finally reaching the storage car.

At the very end is a wall, with on that wall - though it might be difficult to see at first - a message about not attacking it, and a very cute pouty angry face.
