My favorite trope to come out of the tfa kinkmeme is definitely Snoke not having any idea how human biology works. Like he doesn’t really care about these fleshy meatbags, but he thinks he knows enough.
snoke: i see you’ve taken the general as your mate, kylo ren. that is good. it is always wise to build up our ranks. go on then, lay your eggs in him. may his brood be plentiful and thousands strong.
ren: ……
snoke: hopefully it’ll be stronger than his current offspring
ren: …current?
snoke: the furry one in his quarters he thinks i don’t know about.
ren: ….the cat, supreme leader?
snoke: Cat. is that his spawn’s name?
ren: it’s the name of the species.
snoke: Cat is not human? but the resemblance to the general is uncanny.
