Castiel, Angel of the Lord, is the autistic rep we deserve
DEAN.- The general vicinity? That's all you've got?
CASTIEL.- Yes, which is why I need your help. It seems this is gonna involve talking to people (...). But it seems I lack a certain...
DEAN.- Skill?
how wonderful that there's no self-deprecation in Castiel's voice as he acknowledges this, nor is there an ounce of shame! instead he sounds puzzled, like he can't put his finger on exactly what it is that he's getting wrong about human social interactions? he has been studying Social Skills 101 through TV shows, which will surely be enough to pass as A Human Man!
(spoiler alert, it doesn't, because you can have an amazing repertoire and still mess up by not knowing how to tell what is and isn't appropriate depending on the context and the people you're with)
the beautiful thing about Castiel's trouble adjusting to the human world is that he never beats himself up about how unexpectedly difficult it seems to be for him. he's aware that his "people skills" are "rusty", and what does he do about it? he asks for help without it becoming a big deal.
something in the very chill way he goes about this makes me super happy. unlike lots of other autistic-coded characters, Castiel doesn't feel dismayed whenever his lack of social skills gets in the way, and what's more! his friends never shame him for it! yes, Castiel often says things that are inadvertently funny to everyone else for reasons he can't figure out. yes, Castiel misreads social cues more often than not, and whenever he explains his thought process about them out loud it's clear that he has been trying to build himself a mental handbook about Human Interactions For Dummies. yes, Castiel tends to clarify figurative language for others despite it not being something he was asked for, and yes, he often takes sayings at face value and struggles to understand what they mean because he's going off of literal meaning.
and you know what's beautiful about all of this! the fact that neither Dean nor Sam give him hell about it!!
even though there is never any label assigned to Castiel per se, which on the other hand makes sense because when exactly would he find the time and motivation to go get diagnosed... the show makes it clear enough that he is, in fact, on the spectrum. the way he talks is described by alluding to Rain Man, which is about an autistic man played by Dustin Hoffman. Castiel's favourite Heaven is that of an autistic man who's happy to fly his kite in a beautiful meadow for eternity.
Castiel is as explicitly autistic as he can be, and he's never made to feel bad about the struggles that come with it. what's more, though! many of Castiel's most beautiful qualities and choices are directly related to autistic strengths.
for example, the strong sense of justice. Castiel has got a heart of gold that's in the right place, and he can't bear the idea of falling back into line if it means not doing what's right. but he isn't an arrogant assbutt about it. instead of trying to preach some holier-than-thou crap, he thinks out loud about what's right and what's wrong and the consequences that each option comes with. he is genuinely invested in doing what's right.
or the unwavering loyalty and devotion to those he cares for. Castiel loves the Winchester brothers deeply, and Dean in particular, because they listen to him and have actual conversations about the stuff Castiel asks himself questions about. they are the first people who treat Cas as an equal, as a friend, as family. and so Castiel does the same. he loves them enough that he'd rather swallow Purgatory whole to stop Raphael, who is planning on resuming the Apocalypse, than let his brother put Dean and Sam in the line of fire. he would rather protect the family he's found than comply with the Heavenly Plan.
or his extraordinary ability to notice the smallest things. as shown often enough whenever Castiel is taking his time to appreciate what's around him, he has an extraordinary eye for the subtlest details. even when he uses his powers, he is immediately able to figure out stuff in very precise detail.
or his boundless empathy. what enabled Castiel to rebel against Heaven in the first place was his inability to ignore how much Dean was hurting. nevermind how many times Uriel snapped at him for giving the mud monkeys too much credit, or how utterly racist most angels seemed to be towards human beings. Castiel was immediately struck by the pain that Dean felt, and in the end he stood up for what he figured was right because of his willingness to put himself in Dean's shoes to understand his point of view.
or his genuine authenticity. no matter how many times others screw him over and take advantage of how very sensitive he is, and how badly he wants to do what's right and will save people, Castiel still wears his big heart in his sleeve. in a world where most characters lie and deceive and betray and pretend their way through things, Castiel remains genuine in his quest to do the right thing. he keeps being open about his feelings and his motives and what he longs for, even though it is something that can and will be exploited to his detriment, because he doesn't know how to not be his true self.
or his complex and intense emotions. even though Castiel admittedly struggles to express his emotions in a typical way, and at first had trouble identifying and naming them too, there is never half a doubt that he feels them deeply. everything Castiel does is imbued with so much emotion, and if there's one character with a strong sense of transcendence it's him. if there's one character who created free will and stopped Fate dead in her tracks out of love, it's him. if there's one character whose fury was enough to decimate Heaven, it's him. if there's one character whose embarrassment was strong enough to keep him in Purgatory, it's him. there is an explicit acknowledgement, in fact, that Castiel has a larger-than-life heart that's always been a core part of who he is. no matter how many times it lands him in trouble or brings him great distress.
or his great tactic ability to analyse situations. as shown time and time again, Castiel is an extraordinary asset to have in one's team due to his sharp intellect regarding strategic planning. he is Team Free Will's brains, and every time he's involved in a case or an offensive he voices all the foreseeable concerns and possibilities so they can be ready for them. whenever someone is upset or conflicted, and by someone I mostly mean Dean, Castiel is able to analyse everything that has happened to figure out what Dean might be feeling and why. from the very first time they meet, Castiel is able to put together the many pieces of Dean Winchester at the speed of light, and when he himself makes mistakes he has an insane sense of introspection that enables him to realise what happened or didn't happen so he can improve moving forward.
and let's not forget his expressiveness. yes, Castiel's voice is often flat and monotonous. yes, he makes interesting word choices that don't quite land in many contexts. all of this is a clear result of his trouble with unspoken social cues regarding what is and isn't "appropriate" in a certain situation, or with certain people, but he nonetheless expresses so much all the time. in fact, I'd say that he's one of the most emotionally aware characters in this whole show, and he has a fucking ton of lines that are absolute bangers and capture really, really nuanced and complex thoughts and feelings beautifully.
all in all, Castiel is beautiful autistic rep, and I'm so very happy that he exists!!
