Hux is an only child (at least on his father’s side, who’s personal motto is "one and done") but he has a sea of cousins, half siblings, nieces and nephews. If they have red hair, they’re probably connected to the Hux-Kryze family. About once a year Hux makes a mysterious pilgrimage to his family’s home planet. This year he takes Kylo.

+ Nana Bo-Katan is not to be trifled with
+ Hux Sr keeps striking at people’s knees with his cane, loudly declaring how Things Were Different Then and Back In My Day
+ Cousins trying to pick his bones of credits – turns out Hux is loaded
+ Korkie Hux
+ children are drawn to Hux, sensing his antipathy like blood in the water, and he’s usually seen determinedly wading through a gaggle of kids
+ One of these is Hux’s progeny
+ Roughly sorting through the horde to pluck his out and show Kylo
+ This is the first Kylo has heard of offspring
+ Hux doesn’t see the problem (wasn’t Kylo’s business)
+ Hux is bad at parenting, but excellent at officering, so he falls into a weird space between both
+ Hux has convinced this child they were requisitioned from the FO and can be sent back at the first sign of dissent. Kylo suspects this may be true. (it’s not; Hux is just terrible and defaults to threats when uncertain)
+ The kid’s a manipulative little shit and Kylo finds an opponent for monopolizing Hux’s attention
