Oh, right. He punched the ship. Only now does the sting of it register and he should probably let her go get something for it, otherwise he knows he isn't going to bother. Until he can stand upright again, Cassian has no intention of leaving his room. That's standard, when he's come back from missions like this. Locking himself away till he's a functional human being.

Even so, he lets her keep running her hand through his hair, taking a few more minutes of comfort from it before he shifts, letting his grip loosen as he pulls back to look at her face.
