[Out of it is an understatement. Tartaglia doesn't know how to explain to her without frightening her that Columbina is watching them. Or is she? He feels confused, like something's messing with his head. Was that giggling real, was what he even saw real? He starts to question it, but quickly realizes that he's already worrying Yoimiya enough as it is.

So he offers her a small smile, along with a tiny laugh as he throws a hand behind his head.]

Just lost in thought is all. I guess maybe I'm a lot more tired from our trip than I thought. Perhaps it's just the stress of it all is finally catching up to me, and I just need to rest.

[For now, that sounds like a good excuse until he really figures out what's going on.]

But don't worry about me, Yoimiya. You can still keep shopping for now, it's not as if I won't be able to get plenty of sleep while we're on the ship.
