Can't Inigo see that Tidus is enjoying his excuse to sulk over the minor inconveniences in his life? Not that he brushes Inigo off from his shoulders, pouts any less or more for the teasing by his ear. Sulkily answering it in turn:

"You might as well kiss me on the mouth if you're gonna anywhere."

Huff. Tidus touches the end of his nose once, but it's fine really, eyes investigating the wall and then looking back for another pathway. Nothing over his free shoulder, but then he looks over at Inigo, trying to look beyond his head.
