[When Nagito wakes there's a brief expression of flat assessment and calculation before he realizes where he is and what situation he's in (in the desert, dead) and relaxes again. The odds of Celehar attacking him seem pretty low, so he doesn't have any particular need to be ready to spring right now. Instead, he stretches. He hasn't tied off the sleeve of his hoodie, so it just flops over as he raises his arm. It seems like his flesh ends just a little below the eblow.]

You don't need to apologize on my account! It isn't as if this is my bedroom or anything. [Though he'll probably end up using it as temporary accommodations.] It's important to search every building thoroughly, after all.

[Between the passage of time and the nap, you could almost believe Nagito didn't have a loud, dramatic episode just a few hours ago with how he looks now.]
