- Dean Winchester: All right. Any of this scream "clown" to you?
- Sam Winchester: John Wayne Gacy's cigar box. I mean...
- Dean Winchester: We should burn that now.
- Sam Winchester: Oh, yeah.
- Dean Winchester: A serial killer clown. I mean, this is, like, the best/worst thing that's ever happened to you, you know, 'cause you love serial killers, but - but you hate clowns.
- Sam Winchester: Yeah, I get it, Dean.
- John Winchester: All right. Near as I can tell, we have two choices. All right, we can think about what's coming. Or we can be grateful for this time that we have together. Now, me... I choose grateful.
- [kisses Mary's hand]
- John Winchester: So, to whatever brought us together, we owe you one. Amen.
- Dean Winchester: Amen.
- Mary Winchester: Amen.
- Sam Winchester: Amen.
- Sam Winchester: Listen, Dean, there is a wanted poster for you hanging in the post office.
- Dean Winchester: Oh, yeah, no, I-I Googled me, as well. Um, lotta beheadings.
- Sam Winchester: I was right - messing with time changed things.
- Dean Winchester: Well, I mean, I'm still hunting, but you're Internet famous. So, what - is there two of us running around here?
- Sam Winchester: No, I don't think so. I think it's a temporal paradox. We pulled Dad here from 2003, right? So time is self-correcting. Our timeline is changing to this new one.
- Dean Winchester: So, what do you mean?
- Sam Winchester: It means, I think, that, if we don't fix this, then we become those other versions of ourselves. Like, for real.
- Dean Winchester: Okay, well, I'm cool, but you're - ugh.
- Sam Winchester: That's not the point. The point is, if-if all this is different, then what else changed?
- Zachariah: See, I need to know who's been messing with time.
- Caitlin: Excuse me?
- Zachariah: Yeah, we sensed a - well, let's call it a disturbance in the Force. And in Heaven, well, we're - we're not super fond of those.
- Caitlin: In Heaven?
- Zachariah: Yeah, yeah. In Heaven. This town - it's always been a little... muddy for us. Some sort of... interference.
- Zachariah: [to Max, Stacy and Eliot sitting at the table] Hi.
- Zachariah: So, I'm going to ask one more time - who's been playing "Back to the Future"? And you're going to tell me, or he - What's the phrase I'm looking for? He murders you all.
- Castiel: My name is Castiel. I'm an angel of the Lord.
- Sam Winchester: Listen, Jack and Cass are out with Jules and her crew, but when they get back, they can give us a hand cataloging of all this.
- Dean Winchester: Oh, cataloging, fun.
- Sam Winchester: Something like this - maybe it's what we need, you know, to - to take your mind off things.
- Dean Winchester: Things? What things? Oh, you mean that thing that's riding shotgun up in my head? That thing?
- John Winchester: So, you saved the world?
- Dean Winchester: More than once.
- John Winchester: Then it's all true. God, the Devil, you boys smack in the middle. Now you live in a secret bunker with an angel and Lucifer's kid.
- Dean Winchester: Yeah.
- Sam Winchester: Yeah.
- John Winchester: And you've done this whole time-travel thing before?
- Dean Winchester: A few times. Actually, uh, our grandfather, your dad - he's the one who helped us find this place. I think he'd be real happy to know you're finally here.
- John Winchester: Right. Man 'a Letters.
- Sam Winchester: Yeah. W-We're legacies... because of you.
- John Winchester: So, you've, um - you've been busy.
- Sam Winchester: A little bit.
- John Winchester: I-I don't... I-I just... I just wish that I had been there to see it.
- Dean Winchester: Dad, none of this would have happened without you.
- John Winchester: It's good. It's fine. I-I went out takin' out Yellow Eyes. I mean, that was the point, right? I mean, get the thing that killed Mom.
- Sam Winchester: Yeah, yeah, uh, Dad. About Mom...
- Mary Winchester: [enters the bunker] Sam? Dean?
- John Winchester: [teary-eyed] Mary?
- John Winchester: A "temporal paradox"?
- Dean Winchester: That's what Sam's calling it. Egghead. Basically, uh, if you don't go back, Sam never gets back into the life, um, and Mom, she, uh...
- John Winchester: What?
- Dean Winchester: Well, without everything that we did - with God, The Darkness - she never comes back. Sam thinks that she'll just fade away.
- John Winchester: Okay. I mean, me versus your mom? That's - That's not even a choice.
