Crack aside I really think Snoke would have no problem with Kylo/Hux - Hux loves the Order? There's a bunch of lovely fic about Snoke trying to separate them (or ordering Kylo to kill Hux) but I'm pretty sure that irl Snoke would 1) not care 2) shrug it off 3) be like "well all my evil eggs in one basket??? I guess? As long as they use protection I heard humans can get pregnant easily"
Re: Kylo/Hux Snoke ships it but it's not working
