Oh uk what else Carver era did? It changed Cas' status in angelic military society by increasing his status. And that's just another part of how the entire political perspective completely shifts.
In Kripke era, you could interpret Cas and Uriel and Anna as just normal angel warriors. Cogs in the machine. They're not actually privy to any of the plans from upstairs. They're given orders and asked to keep faith and obey no matter what. Otherwise, they will simply kill you. They May try to brainwash you. But honestly that's not the only go to. After like two times of that, if you're still rebelling, they go for the kill. (What they did to Anna, Uriel, for example. Cas does have one period of time when he's brought back in and brainwashed in a non-literal way. But then he rebels even after that and they really do just try to take him out completely). And this established Cas as someone who "led the rescue mission to Hell" as something grandiose. But we see that it's not. It's a retrieval mission if anything. Dean has broken the seal. There's no reason to let Hell keep him anymore. And honestly, even Hell isn't super invested in that. After all, they both want the same thing. Even if the low-level angels and demons don't know it.
(And this makes so much more sense for how Cas supposedly rescued Dean from Alastair and Lilith, who are very serious threats in Kripke era. Cas doesn't actually stand a solid chance against them. Stole Dean from right under their noses. I wonder if they simply put up a fight and then let him do it? Ik Lilith might not even have been in Hell atp but still...just smth to think about.)
Anyways, this establishes the lore of Heaven and Hell as abusive genocidal death cults. The angels who rebel do it because that's the nature of free will, not because they're special rebels or smth. Cas is not a high level angel. He's good but also he's as vulnerable as other angels. He doesn't even have the security clearance to know what the Hell mission was all about. There's a chance he died in Hell trying to retrieve Dean and Heaven certainly wouldn't care. They're only invested in people as assets and liabilities. With an evil nastiness in the mix. That's it.
In this framing, Cas and Dean do have common ground. They relate to each other and Cas chooses to die for Good. He's also risking exactly as much as Dean. They're equals in a weird way. In the nature of their allyship. They eventually work their way to a place of equality and trust.
Carver era Cas isn't this. The Naomi-led Purgatory rescue mission already sets him apart as a special angel. Angels' angel. Shit that honestly any angel could do, but they specifically want Cas to do it. Coz why? Coz he's special. That's it.
The brainwashing is literal now. It's not a metaphor for abuse and going back and forth about your faith and questioning ones' actions based on that faith. Now it's just literal. You can't be blamed for what you did when you were brainwashed. You don't need to take any accountability at all then! You could massacre children and it's not your fault. After all, normal Cas loves kids actually. In fact, he always has. (Lie).
So now Cas is special. He's special because he keeps faith in Heaven even at their worst. He will work on their behalf, in their interests, even at their absolute most evil (bodysnatcher cult leader arc for example). And he's also special coz he's a rebel. He's got the reputation of one. Even though he never actually goes against the interests of Heaven. But see, he's cool and hot and rebellious and all the ladies love him 🥵 and all the kids love him too 🥺. AND his boyfriend is so angry and violent and an idiot, but he's still so chivalrous and protective of him, don't you see?
Here, Cas isn't an equal to Dean. He's not risking the same things as him, for the same things. Cas has his own interest which is to serve Heaven and then maybe Dean. Dean has to be the only one who cares about the little guys. The ones who are truly victimised. Grieving Kevin and Charlie, Claire's assault and trafficking, his own sexual traumas and other traumas...are things he's alone in. Cas will step in to save his soul. Maybe. But he isn't actually there for Dean. (He comforts him in one ep, which was great. But I'm saying on an ideological level). He himself doesn't care for Charlie's death even. Later in Dabb era, he doesn't care about Mary's. He's an angel. He's got interests elsewhere. He just also wants Dean. And he wants Dean to just always Be There. No matter how many times he leaves. (I make this point coz early Cas is actually acutely aware of the fact that they're both always in danger and he makes his moves accordingly. For example, he'll take Dean along to challenge Raphael. Probably Dean won't die from that. He'll die to give Dean a chance to stop Sam. He knows he has to. Etc.).
He's no longer just the lower ranks. Now all his interactions are with powerful people directly. Not only is he privy to shifts in power, he's directly involved in enacting those plans. Sometimes through manipulation, but sometimes not even that.
So ya like I said before. Carver era Cas is the American version of James Bond. He's got the street cred of a working class man who's a rebel against authority and none of the actual rebellion and all of the moral greyness, and the moral "high ground" in the narrative. He's got a love interest along with several women who are into him, and all the kids love him too. He's SPECIAL. He's Cas. Even God is jealous of him for being such a hot jock. He allows himself to be possessed by eviler interests with ease and no struggle. Literally. And you love him anyway, no matter what.
