I want to hear Cas tell Sam and Dean that he loves them and mean it and for Sam to say “we love you too” for both of them and dean just gives a quick and moderately awkward hug and just kind of shrug it off and like maybe give Cas a lil shoulder punch and then tell Sam to man up that’s what I want to see something real and in character and charming and kind of awkward but honest and affectionate and for Cas to understand what a big deal it is to say that and for Dean to be really affected by it even though he doesn’t say anything and for Sam to know and understand more than both of them
