Hux gets hit with some sort of hallucinogenic drug/alien plant spores/whatever. The hallucinations are massively violent and quite frankly are about to drive Hux completely mad. They also cause him to frantically attack the people around himself. Because the crew around him really doesn't want to get their throats ripped out by their General but nobody gets close enough to actually sedate him (let's pretend it's a situation where people are without their blasters they can just set to stun) , they just barely manage to force him into a cell/room/quarantine station to isolate him. He turns the violent actions on himself.

Cue Kylo arriving on the scene and having to knock him out using the force.

Would love to see Hux in the aftermath feeling incredibly guilty about injuring/killing some people of his own crew (while not caring about his own injuries at all).

Huge plus for outsider POV.

Can be either Gen or Kylux.
