So basically I was watching Matilda and went "hey, Hux Sr. really reminds me of the Trunchbull" and immediately went "Matilda could move things with her mind..." And the result was thinking what if Hux Sr. really was like the Trunchbull and the Academy for the First Order has its own chokey etc and Kylo and Hux are there for Reasons and Kylo sees how his co-commander is treated and pulls a Matilda to get revenge in Hux's name.

But then, of course, Hux finds out and is all angry about how he doesn't need magic to fight his battles and anyway the Academy has only ever produced fine officers and really this sabotage does nothing to help the First Order, but is secretly very touched and pleased.
