Naruto startles, not much, but enough, enough for an Uchiha, eyes dim or not; Sasuke would have to be blind not to see it. Startles at his laugh, and that wriggles something entirely different in Sasuke's gut. He still doesn't ask that clarifying question, but the longer they talk, the less he needs to. So he'll just... not draw that much attention to it.

And Naruto settles as he settles, and there's a familiarity there that is so... very... Naruto.

This is nice. (There's that word at last.)

"Dunno," he answers that first question honestly, head tilting. He's not sure why the wings came with him, but also didn't really find it worth deep questioning. The little edge of smile, remnant from that laugh, remains. Comfortable. Quirks a little bit at comparing it to wrinkles in a bath. That's both apt and childish, and isn't that also so Naruto?

But then the blond whirls, and Sasuke's nose (and lip) wrinkles for a different reason as he lifts an arm to shield his face from flecks of mud. "You're disgusting," he scoffs, flippant and almost gentle for such an insult. _{(It's fond is what it is, but don't tell him that.)} "You don't have wings, dobe, but you do have a fucking coating of mud like you've been swimming in it."

Swimming. Ah, that lights an idea. "C'mon, loser." He turns away from his bug-hunting and back toward the beach. He'd rather not continue chattering with a mudskipper.
