It would help a lot when it'd be naturally easier for Inigo to not panic. Sure, in battle situations he can keep himself perfectly calm and serious, even the odds look dire, but any other situation is a disaster when it comes to that sort of thing.

He's trying though. It really helps to have Taiki and Tidus with him, actually physically holding his hands through this - if not just because he doesn't want to disappoint either of them, nor look like a loser in front of them.

So he tries to suck in a few deep breaths, forcing himself to be as calm as he can be in the present situation, and then steps forward.

As his legs move down, he can feel that they no longer hit the ground the way they did up to this point. It's a weird and borderline terrifying sensation, but he repeats 'stay calm' in his head like a mantra and manages to keep himself from instinctively trashing at the sensation, instead keeping his legs still.

(He's totally shut his eyes tight at this point though, as if that makes it a little less scary.

But it looks kind of ridiculous.)
