What if, when Eridan and Karkat meet irl, Eridan is struck by Karkat’s lack of decoration and insists on giving him jewelry and fancy beauty products?
FFFFffpfff bonus points for Karkat seeing him and being like “…wow, he’s still cute but he’s drESSED LIKE A TOTAL DOUCHE.” while Eridan has this total dramatic doki-doki shojo montage going on in his head about how cute and small and pretty Karkat is and how he’s going to be so happy when Eridan pampers him and gives him shiny things.
And Karkat’s like “…WHY THE FUCK WOULD I WANT THESE.”
Eridan being a histrionic nerd and Karkat not taking any of his shit is my favorite way to ship Erikar. XD
