Jules: Sage, pyrite, and sheep's eye? We got that here?
Castiel: Yes. Storage room, red cabinet, bottom drawer. It's marked "gross stuff."
Castiel: The plan is to subdue him using angel cuffs and spell work. They have to get Michael out of Dean.
Jack: And if he doesn't leave?
Castiel: Then they'll try to drive him out.
Jack: And if that doesn't work?
Jack: Cas, Michael has to be stopped.
Castiel: I know, and he will be, after Dean is...
Jack: No, Dean doesn't matter. You're all so focused on trying to save Dean. And I get it, I understand, but if he can't be saved, if it comes down to him or Michael... Michael has to be stopped. Caged or killed...
Castiel: And if that means that Dean dies, too!?
Jack: Then Dean dies. I know this Michael. I've seen what he's done to an entire world, and so have you. If stopping that from happening here means that Dean has to die, then... Do you think he'd want it any other way?
Castiel: At the time of the Great Fall, when the angels were banished from Heaven, I lost what I thought was everything. I had no grace, I had no... wings. I felt hopeless and useless.
Jack: What did you have left?
Castiel: Well... Well, I had Sam and Dean. But I had something else that was extremely helpful. I had myself. Just the basic me, as... as Dean would say, without all the bells and whistles. You know... Sam and Dean, they weren't born with their expertise. They've been at it since they were children. Failing, winning, developing over the years. Patience... persistence... Those are skills, too. The past, where you came from, that's important, but it is not as important as the future and where you're going.
Bobby Singer: Angels ain't known for their veracity. (Cas walks in the room) No offense.
Castiel: None taken. I tend to agree with you.
Castiel: You did well.
Jack: All I did was get punched... in the face.
Castiel: Well, to be fair, we all got punched in the face.
Jack: That's not... Before, when I had my powers, I-I could have done something, and...
Castiel: Jack. You don't... You... You don't have your powers. And you... Your grace should regenerate in time, but until then...
Jack: I'm useless. I can't kill demons, I can't find Dean, and Michael is in our world, and I can't stop him. I can't do anything. I don't have anything.
Castiel: Oh, Jack, that's just not true. You've got me. You have all of us. You have your family. And... And we are going to find Dean and we are going to beat Michael and we're going to do it together. We... Because that's what we do.
Kipling: You see, recently, I had a revelation. You know, somebody asked me what it was as a demon walking the planet, destroying, drinking, defiling... you know, the Three D's... I didn't know. So, I sat back, and I gave it a good think, and I realized exactly what I wanted.
Castiel: And? What is it?
Castiel: What, and you're just gonna leave the rest of us here to burn?
Lucifer: Okay. Hold on a second. Let's slow down, 'cause I... I'm not currently the bad guy here.
Sam Winchester: Yeah, tell that to Maggie.
Jack: What about Maggie?
Sam Winchester: Maggie saw the eyes of the person who killed her... the glowing, red eyes.
Lucifer: You're gonna... you're gonna believe this guy? Come on, man! Sam's a hater! He would say anything to get you on his side.
Jack: Tell me. Tell me the truth!
(Jack compels Lucifer to tell the truth)
Lucifer: She saw me when I was scouting out the bunker. She saw me and she screamed, and then... so I crushed her skull with my bare hands. And it was warm and wet, and I liked it.
Jack: You're not my father. You're a monster.
Sam Winchester: How many are inside?
Castiel: I can hear three. Wait, maybe... maybe four. They're talking about whether Kylie Jenner would make a good mother. The consensus is no.
Dean Winchester: Yeah, well, that's why I'm a Khloé man. All right, we're talking werewolves, which means...
Jack: Silver bullets.
Nazi!Castiel: You align yourself with the h-humans.
Castiel: I vastly prefer them to angels.
Nazi!Castiel: Don't think that you are better than me. Well, we are the same.
Castiel: Yes. We are.
(Cas kills his Apocalypse version)
(In Sam's dream...)
Castiel: Dean, you can't possibly eat another. That's your seventh piece.
Dean Winchester: No, it's not.
Jack: Castiel's right. I counted.
Dean Winchester: Okay, first, don't be a narc. And secondly, seven pieces is perfectly normal.
Sam Winchester: Uh, it's really not.
Dean Winchester: It's not even a whole pie.
Jack: Was he always like this?
Mary Winchester: Even as a baby. John and me, we used to call him our little piglet.
Dean Winchester: All right, I'm done.
Mary Winchester: With love.
(Sam and Mary leave the room and Dean signals Cas to send another box of pizza across the table to him)
Naomi: Every angel is like a walking, talking battery. (Lights flicker) And that is what happens when we run out of power.
Castiel: I don't understand.
Naomi: Well, then, let me make it divinely simple for you. There are a grand total of nine angels in Heaven, present company included. And one or two on Earth, and... that's all. We are the last men and women and divine waves of light still standing, as it were.
Sam Winchester: Rowena, are you at a... party or something?
Rowena: I am, but I'm surprised you recognize the sounds of a party, seeing as how you're all work and no play.
Dean Winchester: Look, we didn't call to talk, we... The world is in danger, Rowena.
Rowena: And I'm currently surrounded by art that makes me think the world should be in danger. Best of luck to you, boys, my three little musketeers. Mwah.
Dean Winchester: Damn it.
Castiel: You know, she's right. You never go to parties.
