Destiel Highschool au where Dean and Cas have been best friend since they were children and totally being in love but too scared to ask the other out and too scared to tell their parents.
So finally when Dean asks Cas to prom Junior year, they end up dating “secretly” even though Sammy obviously knows because well.. Dean is the one who drives him home and he found cas’s underwear in the back seat which wouldn’t be too odd other then the fact that he sees Dean push Cas into walls at school and kiss the living heavens out of him.
So one day Cas and Dean come into deans house and tell Mary that they’ve been dating with their fingers laced together, she calls john in from the kitchen and he just kind of walks in saying “marry what? Im busy so Unless my boy has finally manned up and kissed Cas I don’t wanna hear abou…. Oh hi boys” and Dean just face palming.
(1/2) That's how I thought the finale would be: Dean to be locked with Amara, Cas telling him not to do this. Dean hugs him, and caresses Cas's face, tells Cas that everything is going to be Ok, that Cas has to take care of Sam and Baby now.
