Imagine alpha Pryde get increasingly more and more frustrated and furious because he can’t impregnate omega Hux. They’re both perfectly healthy, why isn’t it working?! Turns out, it’s because Hux doesn’t love his alpha, he loves alpha Kylo. Pryde is furious when he discovers this and attempts to have Ren killed.
OH LORD!
Omega Hux doesn't know what to do. He's been mated to Alpha Pryde for a good number of years but he's never loved him. It was a mating of convenience when Hux was a young man and Pryde was, well, slightly less old.
And now that the pair aren't halfway across the galaxy from each other, Pryde has made it very clear that he expects Hux to carry a litter now. Hux can do nothing but sigh and say 'yes, sir' before coming off his heat suppressants.
He has to tell Kylo. It's bad enough trying to keep away from him whilst Pryde is around but it's going to be hard to explain that he's soon going to be pregnant with Pryde's pups.
Kylo wants to kill Pryde but it would risk upheaval in the First Order since he's an old-style Imperial and there a lot of similar-minded officers who would riot if something were to happen to the Allegiant General at Kylo's hand.
But the pregnancy never happens. Hux endures knotting after knotting after knotting but he never falls pregnant. Pryde is disgusted, having them both tested for fertility issues but none are found.
What neither of them know is that a strained bond in a mated pair will not produce pups. The alpha's seed just won't take in an omega whose heart belongs to someone else and in this case, Hux is so desperately in love with Kylo that Pryde doesn't stand a chance.
After Pryde takes some of his frustration out on his failed omega, Hux takes himself off to see Kylo, unable to keep away from him any longer; it's affecting his health. Unfortunately, Pryde has a spy mouse droid follow him, suspecting foul play somewhere, and he witnesses Hux melting into Kylo's arms and the two sharing a passionate kiss. He hears Hux telling Kylo about how Pryde can't get him pregnant and he thinks it's got something to do with wanting to be Kylo's omega instead of Pryde's, and Pryde crushes the holoprojector with his swagger stick.
He should have known that that bitch would be difficult but he's determined to put a litter in Hux's pretty belly. He'll just have to rid himself of the competition. But he'll never be able to get rid of the dark Force user on his own. He'll have to set a trap, keep his hands clean so that no one suspects him.
He sets a trap. He sends Kylo on a wild goose chase, faking sightings of the Resistance and Rey, fuelling his need for revenge against them and driving him to leave Hux alone on the Finalizer with Pryde. There are trackers on Kylo's TIE so that it will self-destruct with him inside of it when he's far enough away. Pryde will be able to blame Kylo's death on the Resistance and he'll be there to pick up the pieces of Hux's broken heart by filling him with his knot.
Pryde really believes that it'll work. When he gets word that Kylo's TIE has been destroyed, he's ecstatic. What he doesn't know is that Kylo found the devices before he left and sent his ship on a pilotless flight whilst staying behind on the Finalizer, waiting for Pryde to come to deliver the news to Hux; Kylo is waiting for him there with his furious, ignited lightsaber.
Before Kylo kills Pryde, he makes sure that he knows that Hux is pregnant but with Kylo's pups. And they're going to live happily ever after as rulers of the galaxy but Pryde isn't going to live a moment longer.
