There are two seconds when she trips over him, those few moments before she hits the ground, where Cassian's fight instinct threatens to take over, but the thud of her next to him has him blinking into a better consciousness.

It still feels like he's dreaming when she makes her demand though, even more so when she gets up in a huff to finish her walk to the bathroom. Cassian still spends about a minute debating whether or not to listen, but he gets the sense she'll just drag him if he's not in the bed, and he's too tired for that fight now.

He climbs out of his makeshift floorbed and takes the blankets and pillow with him. He hesitates again, because he doesn't think he can sleep against the wall, but what if the outside is Jyn's preference? He sits on the edge of the tiny bed, then lays down there too.

Jyn comes out of the bathroom and makes an immediate beeline for the bed. She's completely unconcerned about his space, settling one knee beside him while she literally just crawls over top of him, muttering something about her wall. She dives back into the blankets, humming about being warm, but it's barely any time at all before he can tell she's fallen back asleep.

Well, okay. That was painless. He settles in more comfortably, his leg brushing hers just from how small the bed is for two people, but it doesn't take long for him to drift back into sleep too. He'll think about how easy it was to fall asleep beside her another day.
