"It would not be the first time." His grandmother never caught them directly, but she definitely knew he'd been sleeping with Jyn in high school. She knew almost everything.

He sighs unhappily when Jyn crawls away, very bereft when she's no longer on top of him. Cassian does not climb out of bed, still just basking in the afterglow even if she's not there. He frowns when he hears one of the doors move, worried she's leaving and running back home in her underwear. It would not be the first time she fled that way.

Instead he hears her voice through the monitor, and he sits up, like it'll let him hear it better. She's talking and singing to Sofia, and Cassian feels like he can melt right back into the bed. She stopped to check on the baby. He smiles, covering his mouth as though she's going to see it. Jyn is singing to Sofia. Everything about this night is proving one happy moment after another.

The singing continues and he can't help it. He needs to see it. He climbs out of bed and pulls on his underwear, tiptoeing across the hall into Sofia's room.

Jyn is sitting in his grandmother's rocking chair, cradling Sofia in her arms, and his heart nearly explodes in his chest. He can't even step further into the room, caught up in the sight of it.
