Michael: When I gave up Dean, you didn't think to question it, to ask why? Dean was... resisting me. He was too attached to you, to all of you. He wouldn't stop squirming... to get out, to get back. So I left... but not without leaving the door open... just a crack.
Castiel: Why wait?
Michael: To break him, to crush and disappoint him so completely that, this time, he'll be nice and quiet for a change... buried. And he is. He's gone. And now... I have a whole army out there, waiting, ready for my command, ready...for this. (snaps his fingers)
Castiel: You know, The Empty said that it wouldn't come for me until I had finally given myself permission to be happy, but with everything we have going on, with... with Michael still out there, I don't see that happening anytime soon. This life may be a lot of things, but it's rarely happy.
Jack: I'm sorry.
Castiel: Hey. At least we have Krunch Cookie Crunch.
Jack: Yeah. We do. Did you take the decoder ring out of the box?
Castiel: Maybe. The secret password is... "Cookietacular."
Jack: Why? Why did you do that?
Castiel: Because I made a promise. Because I love you, Jack. And Sam and Dean... they love you. And they are fighting for you at this very minute. I hope that... They don't need to know what happened here. What I did... I'm... I'm... I'm at peace with my choice. I don't want them to worry.
Jack: I won't tell them. I promise.
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.
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.
