Even though the angle is awkward, Cassian can still see the way her face shifts, can hear in her tone that she's putting whatever is happening between them on herself - and it's not the case. They can be terrible at communicating. He feels like he's still saying all the wrong things.

"Some of it is me," he says, matter-of-factly. Rey starts to make tiny sleepy noises, like she's finally letting herself drift off. Or maybe she's just too tired to keep awake anymore. Either way, Cassian isn't going to move or stop his humming until she's totally conked out.

"I don't want you to feel like you have to avoid me. I..." He breaks off to murmur-sing a few words when Rey wriggles. "I like seeing you, I like doing this with you."
