#okay while this line is hilarious and whatnot #i actually read it as something a little bit sadder #because in this episode Dean is pushing everyone away #trying to make them WANT him to say yes so he’ll be gone #he tells Bobby ‘you’re not my father’ #knowing that’s where it’ll hurt him the most #he tells Sam ‘I don’t believe in you’ #knowing that will cut the deepest #but what does he say to Cas? he makes a bunch of mocking sexual references #I think he knows that Cas is attracted to him #and this is him calling him out on it #to try and makes Cas angry and hurt #this episode is Dean trying to convince his family that they don’t want him #so he goes for their weak spots #and Cas’s weak spot is the fact that he’s in love with Dean
