Her posture is completely different by the time she slips back in, and Cassian frowns, the tiniest bit, barely noticeable. It's not unusual for her, but it feels like he's missed a chance to fix it, to keep that calm, happy atmosphere.

He watches Jyn circle around, but he doesn't miss Rey confusing herself. She flails her arms again hard, scrunching up her nose, and letting out a surprised noise when the toy falls out of her hand to land next to her. She looks down at it and stares, like she's expecting it to leap back. Cassian laughs at her again, but he looks back up to Jyn. She doesn't usually offer, but he nods. "I would like to, yes."

He's not ready to step out of this bubble yet, even if it only lasts until Rey falls asleep.
