Hux is very disciplined about his less-than-dignified sexual urges, but he's on the verge of snapping from denying himself for so long. He decides to indulge himself just this once, but can't risk giving up power or control. He goes through stormtrooper records, finds out which ones are on alpha suppressants, and makes arrangements to "inconveniently" get stationed alone with one of them, after altering the trooper's med schedule of course. FN-2187 will probably need reconditioning anyway so it's perfect, and for now his inappropriate empathy will be useful for Hux's needs.

All other background ships are welcome. (I headcanon Kylo as beta or omega in this, so if he's in it then plus for omega or beta!Kylo.)
