Kylux
So, I could be misremembering but…during the last battle, Kylo gives orders, but they’re carried out only after Hux gives the same ones. And when Kylo orders fire on Luke and Hux doesn’t echo him, Kylo basically has to repeat himself before anything happens. Clearly, everyone’s waiting on Hux.
And I am so here for Hux having the military’s loyalty more than Kylo and the power dynamics/struggle this could result in.
ETA: since then confirmed that I remembered correctly :D
