I actually do not know oodles about the knights of Ren,but I had this humorous concept of Hux suddenly revealing he was some sort of sleeper knight of Ren all along. He had ample clothes to hide under.
Snokes secret babysitter. Stuck with kylo, poor Hux.
ah well, just have a sketch regardless. I may do a full view of this cause damn, Hux would make the stingiest most cold hearted, majestic Knight.
