god dean's reaction to meeting gay people will never fail to amaze me. he's so surprised but also genuinely curious and you just get the feeling that he hasn't had the chance to be around queer people much in his life which makes me so sad but also so happy for future dean who will surround himself with queer friends and family.
i just watched 5x09 the real ghostbusters and the scenes with dean at the end just really got to me. like here he is when he finds out the guys they've been working with are a couple:
and then the next time we see him in this episode he's leaning against the impala with the absolute cutest smile. like.... seeing someone, dressed as him, be openly gay made him smile like this!
and finally sam shows up and asks if he's okay and there isn't really a whole lot to explain his answer except that he just found out that the guys who helped them on the hunt, guys who idolize the characters sam and dean, are gay and in love.
i just think everything about this is really so cute
