Dean Winchester: Nerds.
Sam Winchester: Takes one to know one.
Dean Winchester: What?
Sam Winchester: You. Come on, man. You're always calling me a geek, but you know every word to every Led Zeppelin song... backwards and forwards... you can discuss in detail every major rock drummer between '67 and '84, and... you watch "Jeopardy!" every night.
Castiel: You should never have tried to lock him away.
Dean Winchester: You know what? You're right. I never wanted to put him in that damn box. I wanted him dead.
Dean Winchester: He's dangerous, Cas, and you knew it! You've known it for a long time! But that's okay. You know why? Because me and Sam, we've killed just about everything there is. And this... Jack... oh, we'll find a way. Because he's just another monster.
(Sam is lookin' at old photos...)
Sam Winchester: I mean, Dean couldn't have been but 4 years old. I wasn't even 6 months. Just...
Bobby Singer: You know, at one time, you boys were good-lookin'.
Sam Winchester: Thanks.
Castiel: A Hunter's memorial, complete with monster. Mary would have appreciated that.
Bobby Singer: Now that you mention it, yeah.
Dean Winchester: We know it wasn't easy for some of you to get here, and we thank you. We... We gave her a Hunter's send-off a few days ago. But we know that her family went beyond just us. Some of you Hunted alongside her. Some of you fought Michael with her in the other world. You know, we lost our mom once before. But we got a second chance with her. And we got to know her not just as "Mom," but... as someone who was tough and strong. Stubborn as Hell. Someone who had opinions and wasn't shy to use them. She could handle a machete. She could handle a vampire. She could handle our old man. She couldn't cook worth a damn. Mom, you weren't here long enough. But we're... we're so glad for the time that we had. Goodbye, Mom.
Sam Winchester: Bye, Mom.
Everyone: To Mary.
Castiel: I know you know this, Mary, but, um... Sam and Dean... they're... They're glad to have you back. Whatever you still have to deal with and however long it takes, you should know they're happy. I mean, finally, they don't have to be so, um... so alone.
Mary Winchester: Castiel. They were never alone.
Jack Kline: You know, Sam and Dean, they were grateful.
Mary Winchester: If Sam and Dean saw what you did, they would be as worried as I am.
Jack Kline: Are you gonna tell them?
Mary Winchester: You need help, we'll help you. We're your family.
Jack Kline: You can't.
Mary Winchester: We care about you, Jack.
Jack Kline: No, just leave me alone.
Jack Kline: Mary. Nick... he was a bad person, a killer. I had to stop him.
Mary Winchester: Not like that.
Jack Kline: He deserved it.
Mary Winchester: Take me home, Jack.
Jack Kline: I-I will. I will. I-I just... Tell me it's okay.
Mary Winchester: It's not. You're not.
Castiel: Anael. You know, you're not always right. Just because God's not with us doesn't mean we're alone.
Anael: Why? Because we all have each other?
Castiel: I'm doing this for Jack.
Anael: No, you're not. You're doing this because you're afraid. Because in your mind, it'd be easier to call God than to tell Sam and Dean Winchester the truth.
Castiel: The truth?
Anael: Jack's soul is gone, Castiel. And there's nothing you can do about it.
Castiel: And here I thought you just performed miracles for the money.
Anael: Well, you haven't been paying attention, then. I do them for me. I don't need Heaven. And I don't need God. And... I'm happy, Castiel.
Castiel: Really? Because that sounds lonely.
Anael: We're all lonely, because we're all alone. From ant to lion to human to angel. Every last one of us.
Castiel: You know, he does meddle. God reached down, and he brought me back to life.
Anael: So he saves one angel... and watches millions of people die screaming, every day. What does that say about him?
