Every star destroyer has its own general, and each general has been assigned a Knight of Ren. Hux has regular conferences with the other generals who usually end up talking about how amazing their knight is, how helpful, powerful etc
Cue Hux being angry and bitter as hell because even though he got the leader, compared to the others Kylo Ren is just a tantrum-throwing manchild who challenges Hux's authority all the time.
Bonuses: -Hux has to lie to the other generals and brag about how helpful Kylo is, even though the repair bills are through the roof -If they find out the truth and make fun of Kylo, Hux turns the tables on them and brags about how fantastic/flexible/kinky/obedient Kylo is in bed.
