Instead of the Alpha being the leader of a pair, and the Omega having subservient instincts, it's the other way around.

Alpha instincts are just as much "protect" as they are "take care of" their Omega, and so it usually ends up in them pampering their Omega and being very subby tops during heats.

Hux and Kylo are mates. While they still argue in public about command of the Finalizer, when they go back to their chambers they slip right into those gender roles.

I'm fine with either Kylo and Hux being the Alpha.
