Riverdale Incest Tournament

Polly/Cheryl

The repressed lesbianism of being in love with your (dead) twin brother's girlfriend.....

Veronica/Hermione

Hiram/Veronica

Where to even start with them. They are the center of each other's world to an unhealth degree. Hermione is jealous of Veronica. She was diagnosed with incest in s4.

Cheryl/Betty

Veronica/Hermosa

They have such chemistry they should have fucked.

Edgar/Evelyn

Just a cult leader and his daughter-wife who he groomed into recruiting new cult members for him

Betty/Hal

Another one in the "basically canon" category and I'm not even talking about whatever the fuck was happening with the Black Hood in s2

"retroactively makes dark betty seem trauma-induced"

Bughead

Vote Bughead because I'm haunted by that time they cut from falice in a post-coital embrace to the image above. I know the show didn't get weird with it but they SHOULD have.
