Dean Winchester: My whole life, I always believed that what we do was important. No matter what the cost, no matter who we lost, whether it was Dad or... or Bobby or... And I would take the hit. But I kept on fighting because I believed that we were making the world a better place. And now Mom and Cas... And I... I don't know. I don't know.
Sam Winchester: So now you don't believe anymore.
Dean Winchester: I just need a win. I just need a damn win.
Dean Winchester: Dude, what is going on with you?
Sam Winchester: What are you talking about?
Dean Winchester: All day. You give me a-a beer for breakfast. You... you gave me Agent Page, which you always like to be. You... you didn't whine about me blaring my music the whole way here. And when we stopped for lunch, you ordered me chili fries.
Sam Winchester: You love chili fries.
Dean Winchester: Everybody loves chili fries. That's not the point. Now you wanna go hang out at a strip club? You hate strip clubs.
Sam Winchester: No, I don't.
Dean Winchester: Dude, the last lap dance you had was... was at Christmas. It was a gift paid for by me. You spent the entire song trying to convince the girl that she should go to nursing school. So what is it? It is my birthday? Did... did I win a bet that I don't know about? What?
Sam Winchester: No, nothing. Nothing. I-I mean, I'm just trying to be nice.
Sam Winchester: Our mom, Mary, she's trapped on the other side. If we can get your powers back, maybe we can open that door up. Maybe...
Jack: You wanna save her.
Sam Winchester: Yeah. Yeah, I do. But... if this doesn't work, if that can't happen, that's okay, because I do care about you. But I should've told you. I'm sorry.
Jack: Sam. Why are you being so nice to me?
Sam Winchester: Because I know what it feels like to feel like you don't belong, to feel like there's this darkness inside of you, to be scared of who you are, what you can do. Dean, Cas... my family helped me through that. So now I wanna help you. Because you're not evil, Jack.
Sam Winchester: Dean doesn't hate you. It... Look, sometimes the wires in Dean's head get crossed and... and he gets frustrated, and then he mixes frustration with anger, and... and... and fear.
Jack: Why would he be afraid?
Sam Winchester: Because Dean feels like it's his job to protect everyone. And right now, we need to protect you. But we may also need to protect people from you.
