Thankfully for Tidus, it does seem like the worry is flying way over Inigo's head. It's hard to think of when he isn't following the exact same train of thought, after all, and the reason Tidus himself provides is very believable.

.. well, that, and then there's also the fact that Inigo is just happy to know that Tidus is going to come to bed with him, rather than sitting here by himself, getting existential in the worst way possible.

So Inigo quickly steps to catch back up with Tidus, following him back in the direction of their room.

"Ah, right.. Hopefully it should be alright, since he didn't come rushing over. And Jumblie's there with him." And Inigo knows the sunshine higgledy is a great source of comfort. "They'll probably still be waiting for us together."
