I'd love to see something red and fluffy between Dave and Karkat, maybe involving the idea that Dave can't sleep in the veil because he's convinced he'll be attacked? Seeing super competent leader Karkat would be awesome too.

See, okay, you are the best of housemates. It is definitely you. You don’t even fuck with his goddamn color-coded shit in the fridge and you absolutely do not go anywhere the fuck near his color-coded toothbrush major arcana in the bathroom. For the most part you kind of stand over here and let his weirdness just kind of handle itself. You have, however, reached your limit for this particular style and model of bullshit and so you bang on his door and when he sort-of grunts in response you bang on it again and then you try the knob and hey, check that shit out, it’s not locked. ...Wow, he looks like ass.
