Perhaps I've posted this before, if so I couldn't find it. But I wanted to go back to the actual content of Dean's prayer to Cas in The Trap.
Because I keep seeing repeated that Dean apologized to Cas for being angry or that this speech is authorial voice of Robert Berens condemning Dean for being angry.
Neither of those things are what is actually going on.
What is going on is a raw but tender examination into Dean's psyche, his fears about himself, and of losing Cas, and Dean allowing himself to express soft emotions after he has expressed understandable more negative ones--anger, hurt. There has to be room for both. If there is only room for the negative ones, that's not good. If there is only room for Dean to be soft, and he doesn't express his anger and his hurt, that's not good. Berens has frequently written Dean expressing himself on the range of both types of emotions, the tenderness and the anger. Dean's fear, Dean's self-blame, does not equal authorial voice condemnation.
DEAN: No, no, no. [Dean looks around and then speaks quietly in prayer] Cas? Cas, I hope you can hear me... that wherever you are, it's not too late. I should've stopped you. You're my best friend, but I just let you go. 'Cause it was easier than admitting I was wrong. [Dean breaks down, sniffles, and then kneels at the base of the tree]
I β Ohh. I don't know why I get so angry. I just know β I know that it's β i-it's just always been there. And when things go bad, it just β it comes out. And I can't -- I can't stop it. No matter how β [Sniffles] how bad I want to, I just can't stop it. And β And I β I forgive you. Of course I forgive you. I'm sorry it took me so long β [Sniffles] I'm sorry it took me till now to say it. Cas, I'm β I'm so sorry. Man, I hope you can hear me. I hope you can hear me. [Sniffling] Okay.
What is Dean apologizing for? Letting Cas walk out without saying that's not what Dean really truly wanted to happen. Dean's anger is valid and the text treated his anger as valid, but Dean is fearful of his own anger. A consistent theme Berens works with more than once, but not condemning Dean. Illustrating and exploring Dean's pov, his self-doubts.
From 15.18 Despair, also by Robert Berens (bolding mine):
DEAN: We'll lose. (walking slowly towards the back wall of the room, hopeless) I just led us into another trap, all because I couldn't hurt Chuck. Because I was angry and because I just needed something to kill, and because that's all I know how to do.
CASTIEL: Dean... (approaches him)
DEAN: It was Chuck all along. We shouldn't have left Sam and Jack. We should be there with them right now. (tearfully) Everybody's gonna die, Cas. Everybody. I can't stop it. (approaches Cas) She's gonna get through that door.
CASTIEL: (quietly) I know.
DEAN: And she's gonna kill you, and then she's gonna kill me.
Notice the repeat on the phrase "I can't stop it"--and it's about his loved ones getting killed and Dean believing it's his fault and that's what Dean really meant in The Trap but he didn't articulate it that way because people are messy and Dean is a complicated deeply loving character with a lot of self-doubt and fears, and Robert Berens understands this.
And we know what happens next, and wow, Cas hearing Dean saying "that's all I know how to do" must have absolutely SENT Cas. Seeing how harshly Dean sees himself. Cas absolutely snapped in a very positive way and unleashes his beautiful speech that is a tribute to Dean in general, not just Cas's own expression of love for Dean.
Dean's expression of self doubt are not an authorial condemnation and meant as statements of objective truth. Unreliable narrators are part of the tools of fiction, and Berens' scripts do tend to work with complex emotional entangled ways, they're pretty deeply layered. As well as compassionate and empathetic, if often raw.
I'm thinking too of what Berens wrote for Dean in "Who We Are" with Dean's heartfelt confession to Mary that was resentment and love in equal measure and is one of the show's strongest emotionally real moments and was really good for Dean to be able to express that, in S12.
DEAN: You left us. Alone. 'Cause Dad was just a shell. His perfect wife? Gone. Our perfect Mom, the perfect family... was gone. And I... I had to be... more than just a brother. I had to be a father and I had to be a mother, to keep him safe. And that wasn't fair. And I couldn't do it. And you wanna know what that was like? They killed the girl that he loved. He got possessed by Lucifer. They tortured him in Hell. And he lost his soul. His soul. All because of you. All of it was because of you. I hate you. (Deans voice breaks as tears run down his face) I hate you. And I love you. 'Cause I can't β I can't help it. You're my Mom. And I understand...'cause I have made deals to save the ones I love more than once. I forgive you.
Also a reminder that forgiveness is not always for the recipient. Forgiveness is sometimes because the person needs to do the act of forgiving, for themselves. It's a catharsis.
And the ongoing deliberate irony some of the writers deployed, which is not Dean-shaming, or feelings-shaming him, but the irony that Dean is the most loving, most open, most hurt, most big-hearted character on the show while Dean himself thinks he's the angry one, he's good for nothing but the kill, and that's all he is--that cuts like a scalpel, in a good way.
This is powerful. It's good. It's complicated and this is the writing of someone who cares about Dean and thinks deeply about his psyche.
