In the time between Jyn collapsing down on the bed and Cassian (unbeknownst to Jyn) emerging from the shower, she must've dozed off and floated in the strange purgatory between fully restorative sleep and the waking world. The sound of the fresher door stirs her slightly, eyes still sticking together until she manages to groggily and lethargically peel them apart in response to the noise she can't quite place. She begins to yawn and rub at one of her eyes when she scans her surroundings, subconsciously searching for whatever the noise had been that had woken her, when she's greeted with the .. startling (but not at all unwelcome) sight of Cassian's naked form (which she knows in the fraction of a second from sight alone).

"It's a good thing I'm not prone to getting flustered," she murmurs lightheartedly, voice still thick and scratchy with lingering sleep.
