Dean looking at Doctor Sexy.
Dean looking at Cas.
The little nod that Dean does in the second gif…
The way his lips twitch into an almost smile when he sees Cas… priceless :)
I really love the way the entire scene was shot. A lot of people have pointed it out, but the way it was built up actually mirrored the date on prom-night sweeping down the stairs, stealing the boy’s breath. Of course it was meant to be funny/ironic, but in a very sweet and adorable way. After all, Cas is still a guy with a stubble and an ever-present frown; the coat and cheap suit do not really look that good on him, and the way he presents himself is awkward at best.
But Dean’s reaction is all joy and adoration, probably because that awkward angel in his ugly over-sized trench coat has come to mean so much to him, and he just realizes he never wants to miss him again.
Of all the scenes that hint at some sort of physical attraction between those two, this is the one I liked best. It was funny, but it didn’t make fun of Dean and Cas.
I guess what I love about Dean/Cas is that they are so much about that sappy old trope of loving/being attracted to someone’s soul. It’s clearly the case with Cas, who basically fell in love with Dean’s soul, but in Purgatory and afterwards, it’s become actually obvious that Dean feels the same: he may not normally do guys (not openly anyways), and though Jimmy certainly wasn’t ugly, Cas just drowns in his clothes and he’s all awkward and complicated, but I think in that scene, Dean realizes that for him, it’s really just about the fact he’s Cas.
For me, this symbolizes such a fundamental human craving we’ll probably all have in one way or another, which is to be loved for who we are, rather than for what we do, what we look like, or what we pretend to be.
Dean/Cas is such a perfect embodiment of this old-fashioned romantic idea that I cannot help but feel a little like tearing up whenever I see Dean look at Cas in that scene.
