What it says on the tin. Jonathan is a stoner, and we know from season three Steve smokes at least occasionally. Maybe they get Nancy high on sativa first, and she loves what it does to her writing drive, and her sex drive. Or maybe it’s indica, and she can feel her body finally lose tension for the first time in years, and she just wants to lounge on the bed and make out with her boyfriends. Stoned sex, please!
