Cassian catches her movements out of the corner of his eye and wonders. Jyn always hid her emotions in a different way from him, but he'd always been able to pick at some of the pieces of hers.

He stops wondering. He doesn't - can't - think about what she's thinking. Instead he lets the silence stick around and hang heavy in the air, because even the thick uncomfortable tension between them is better than asking her about it. He has to stop trying to parse her thoughts.

It doesn't mean he doesn't feel like he's going to burst by the time they reach the city. At least passing through the checkpoint gives him something else to focus on while he digs out their papers.
