Oh, geez. Tidus may be bringing it up pretty casually, almost joking, but Inigo can only imagine how that situation must have played out in reality. Gyousou in danger, Taiki desperate to save him, Tidus startled about the whole thing..

And Inigo had no idea that any of it had even been going on. It makes him feel a little guilty, though he thoroughly pushes the feeling down. This is about Taiki right now - don't think he doesn't notice Tidus making sure to shift the topic back to Taiki as well.

"If you want to show us," is the natural answer to that question. Of course he'll look at Taiki giving a form shifting demonstration. It's only the other's embarrassed reaction that makes him be a little gentle about it, rather than going full out enthusiastic right now. "But if it's too much, then don't worry about it! Really, Tidus has already seen it, and I can wait."
