She starts to excitedly bounce in his arms, and Cassian starts to feel settled. His smile deepens more.

"Do not take a flying leap with your clothes on, you silly star."

The baby's got the wriggles, but he honestly appreciate the effort it takes to finagle all her clothes off while she refuses to stop bouncing. Jyn helps, Jyn laughs, Rey laughs, and the sounds of it begin to chase out the trauma. When the water is warm and full enough, he plops Rey inside the tub to her very eager delight, and the three of them together make a mess of bathtime. Their daughter soaks them, but she gets clean, and if she gets to play in the water a little longer than normal, Cassian can't say he minds.

No matter what he does, he can and will still love them, just like they love him.
