Kylo kills Snoke and becomes Emperor. Hux flees, figuring surely Kylo will see him as a threat and kill him next. Kylo has him hunted across the galaxy until finally he’s brought in, angry and disheveled. To his surprise, rather than imprisoned he’s cleaned up and given food and clothing. Turns out Kylo didn’t find him to try to kill him; he wanted to finally confess his feelings for him without fear of consequences, and now he can.
