So I have this head canon that keeps coming back to me that, after the war, Cassian and Jyn end up running a foster home on accident after taking in as many stray children as they can feed/house. Because both of them obviously have a soft spot for children who have lost everything.
Also, they are particularly good with teenagers with attitude. Because they understand that the attitude is just their way of protecting themselves from getting hurt again.
Also: Grandpa Baze and Grandpa Chirrut are there, along with Uncle Bodhi and Uncle Kay - who for the sake of his pride still feels the need to insist that he can’t be an uncle because he is not biologically related to Cassian (but everyone knows he likes it because his optical sensors flash very quickly whenever someone calls him that, as if he’s blinking away happy tears.)
