Sasuke lets Naruto think aloud to himself, unhurried. Finds he doesn't mind it, hearing Naruto come to conclusions out loud. Especially since the conclusion really is as nonsense as it is completely accurate: who would think their way down this path naturally? Who has space in their schema of normality for world-hopping? (Obito doesn't count.) So the halting path isn't something he can fault Naruto for, really.

Naruto's condemnation, though, is so very Naruto that Sasuke's nose wrinkles for a second, and then he can't help himself. He fucking laughs.

It's soft, and it's rusty from disuse still, but it's not a scoff, and it's not a cackle, and it's completely sane, thanks. It only lasts a few beats, and it's not as bright a sound as most people seem to make out of the action, but it's natural and it's calm. "It is dumb," he agrees. He really can't argue that. "But I was stuck there outside time for a couple years, so. Got kinda used to it."

His free hand settles on his hip, and his stance relaxes. Not that he looked tense before, just ready in that ninja way, guard up but casual. He's still Sasuke, so of course his guard isn't down, isn't even down when he's asleep, but he's not holding himself in that way that he carries around like a mantle. Yeah. He'll take this, too, same as Naruto.
