Castiel: You know, I've been here for a very long time. And I remember many things. I remember being at a shoreline. Watching a little gray fish heave itself up on the beach, and an older brother saying, "Don't step on that fish, Castiel. Big plans for that fish." I remember the Tower of Babel, all 37 feet of it, which I suppose was impressive at the time. And when it fell, they howled divine wrath. But come on, dried dung can only be stacked so high. I remember Cain and Abel. David and Goliath, Sodom and Gomorrah. And of course, I remember the most remarkable event - remarkable because it never came to pass. It was averted by two boys, an old drunk, and a fallen angel. The grand story. And we ripped up the ending, and the rules, and destiny, leaving nothing but freedom and choice. Which is all well and good, except... well, what if I've made the wrong choice? How am I supposed to know? But I'm getting ahead of myself. Let me tell you my story. Let me tell you everything.
Castiel: Don't worry about the Winchesters.
Crowley: Don't worry about... what, like Lucifer didn't worry? Or Michael, or Lilith, or Alistair, or Azazel didn't worry? Am I the only game piece on the board who doesn't underestimate those denim-wrapped nightmares?
Rachel: What does God want?
Castiel: God wants you to have freedom.
Rachel: What does he want us to do with it?
Castiel: [narrating] If I knew then what I know now, I might have said, "It's simple. Freedom is a length of rope. God wants you to hang yourself with it."
Castiel: [narrating] After supposedly saving Sam, I finally returned to Heaven. Of course, there isn't one Heaven. Each soul generates its own Paradise. I favor the eternal Tuesday afternoon of an autistic man who died in a bathtub in 1953.
Castiel: [narrating] Those first weeks back in Heaven were surprisingly difficult. Explaining freedom to angels is a bit like teaching poetry to fish.
Sam Winchester: Look, Dean, he's our friend, too, okay? And I'd die for him, I would. But... I'm praying we're wrong here.
Bobby Singer: But if we ain't, if there's a snowball of a snowball's chance here, that means we're dealing with a Superman who's gone dark side. Which means we gotta be cautious, we gotta be smart, and maybe stock up on some kryptonite.
Dean Winchester: [to Sam] This makes you Lois Lane.
Crowley: What are you planning to do about Raphael?
Castiel: What can I do, besides submit or die?
Crowley: "Submit or die"? What are you, French?
Raphael: You'll kneel before me and pledge allegiance to the flag, all right?
Castiel: And what flag is that?
Raphael: Me, Castiel. Allegiance to me.
Castiel: Are you joking?
Raphael: Do I look like I'm joking?
Castiel: ...You never look like you're joking.
Castiel: [narrating] So, that's everything. I believe is it what you would call a... tragedy from the human perspective. But maybe the human perspective is, limited, I don't know. That's why, I'm asking you father; one last time. Am I doing the right thing? Am I on the right path? You have to tell me; you have to give me... a sign. Give me. A sign. Because if you don't I'm going to cho- I'm going to do whatever I... whatever I must.
Crowley: [torturing a vampire] Chocula here feels every tickle.
Castiel: What is that good for?
Crowley: Apart from the obvious erotic value, you got me.
Dean Winchester: Why are you here?
Castiel: I want you to understand.
Dean Winchester: Oh, believe me I get it. Blah blah, Raphael, right?
Castiel: I'm doing this for you, Dean. I'm doing this because of you.
Dean Winchester: Because of me. Yeah, you gotta be kidding me.
Castiel: You're the one who taught me that freedom, and free will...
Dean Winchester: [interrupting Cas] You're a freaking child, you know that? Just because you can do what you want, doesn't mean you get to do whatever you want!
