I will never get over how great an actor Jensen is, how completely he can take on the role of Dean. Just look at that face. Look at it. It dissolves after he hears and processes the words Cas just told him. His face loses all tension and just sags. His head inclines in realization. He doesn’t take his eyes off Cas until he hears his brother come in, and when that happens he has to look away, compose himself, because Sam is here and is face is swimming with emotions.
I can’t look at images like this anymore from this season and not chalk it up to something deeper than a friendship. The closeness, the going-through-my-stuff-and-not-caring, the lack of personal space, emotional chats, openness… Sure, friends do that, but really, I don’t even go through my best friends belongings (let alone their toiletries) without feeling awkward, and I would feel awkward if they just randomly started going through my stuff too (and they never have before) because they are my friends and “uh that was weird…”. If my partner went through my crap though, why would I care? I am more intimate with that person than my family or my friends, so why should their closeness bother me? It doesn’t. Just like Cas doesn’t bother Dean anymore.
