Jyn manages to sleep, exhausted more than she's ever felt in her life, including prison and childbirth. The shame and stupidity and heartbreak is too much and she silently cries herself to sleep for a few hours, fitful and not incredibly restful.

She jolts awake and assumes it's because Rey's crying, but she only hears the quiet murmur of Cassian. Probably singing to her again. The familiar tingle in her chest pulls her off the couch, knowing Rey will be fussing to eat soon, and Jyn reluctantly pads from the living room to linger by the half closed door, just out of sight.

It's not that she's unwilling to go into her own bedroom it's just that... she's unwilling to go into her own bedroom.
