Intro. Detailed scene. Late evening, Dean picks up Cas to give him a ride home (or to his apartment, because Cas again "doesn't want to be alone" ). The car is cramped, Cas is sitting too close, their shoulders touching. What are they talking about? Cas gets into Dean's head again with questions: "Why do you get angry when I'm around? This is not rational" . Sparks.
