Tidus takes the band, a frown on his face, a 'bah' muttered under his breath. But he's going over to where Taiki's clothes are to pick them up for the guy when Inigo asks his question. That is an idea but...

"It's still going to fall off though, if Taiki goes from kirin to human again," he points out, disappointed. "Unless we just stuck the band around a string? But-"

While that might be a thought, he looks between Inigo and Taiki, while putting himself in a spot where his back is facing the corridor of the carriage.

"We should just give it to Saku, right? Taiki's always going to be where Saku is." A beat, and then he gestures Inigo over to him. "Inigo, stand here? Unless you wanna change back, Taiki. We can make a screen for you, in case anyone comes in!"

It's your human meatshields, Taiki!
