- Radio DJ: Our flashback playback continues with a song that climbed up to number four on the charts. Here's Alanis Morissette's "Ironic".
- [Castiel shuts the radio off]
- Metatron: Really? That song is a classic.
- [Cass gives him an annoyed look]
- Metatron: Yeah, I hear you. I do. And you're right. Inclement weather on the day of your nuptials... and the wrong cutlery at inopportune times is hardly ironic. But it sure is catchy.
- Dean Winchester: All the spells they used came from a book of unspeakable evil, which they lost nearly a hundred years ago.
- Sam Winchester: Okay, so they're bad. So what? We've faced worse.
- Dean Winchester: Sam, read the file. The way the book works is when you use it, there is a negative reaction--I'm talkin' biblical negative. Dark magic always comes with a price--we know that, we've been down that road before.
- Charlie Bradbury: Well, let's at least translate it and see what it says.
- Dean Winchester: You guys don't understand--the book's been calling out to me ever since I laid eyes on it, okay? Calling out to the mark. I can hear it like it's alive--it wants me to use it, but not for good. Look, I wanted it to be the answer too--I really did, but we have got to get rid of it. Burn it, bury it... I don't give a damn. WE'll just have to find another way to fix the mark.
- Sam Winchester: LIke what?
- Dean Winchester: I don't know.
- Charlie Bradbury: So you're giving up?
- Dean Winchester: No, I'm not giving up. I don't have a death wish, and even if I did, I can't die! Not with this thing on my arm, but what I can do is fight it as long as I can until...
- Sam Winchester: [standing up] Until what? Tell me. Until what, Dean? Until I watch you become a demon again? Until then? I can't do that--I won't do that.
- Dean Winchester: Well then, you'll just have to lock me up--bind me to the bunker like you did last time.
- Charlie Bradbury: [standing] That doesn't solve anything.
- Sam Winchester: Look, just let us translate the book, okay? If there's a cure, we'll do it and deal with the consequences later. I can't lose you.
- Dean Winchester: Really?
- Sam Winchester: [with conviction] Yeah, really.
- Dean Winchester: You change your mind on that, cause that's not what you said last time.
- Sam Winchester: Come on, man, you know I didn't mean...
- Dean Winchester: [interrupting] This is my cross to bear, Sam--mine, and that book is not the answer. Now we gotta destroy it before it falls into the wrong hands, and that includes me!
