- Dean Winchester: It's already gone too far, Sam! If I didn't know you, I would want to hunt you - and so would other hunters.
- Sam Winchester: [after Dean confronts Sam about using his powers] You were gone. I was here. I had to keep on fighting without you. And what I'm doing, it works.
- Dean Winchester: Tell me, if it's so terrific, then why'd you lie about it to me? Why did an angel tell me to stop you?
- Sam Winchester: [Sam looks up, startled at Dean] What?
- Dean Winchester: Cas said if I don't stop you, he will. See what that means, Sam? That means that *God* doesn't want you doing this. So, are you just gonna stand there and tell me that everything is all good?
- Sam Winchester: [to Jack] You've got this dark pit inside of you, I know, believe me. I know. But that doesn't mean you have to fall into it. You don't have to be a monster... It doesn't matter what you are, it only matters what you do. It's your choice.
- Dean Winchester: Sam loves research. He does. He keeps it under his mattress, right next to his KY. It's a sickness, it is.
- Jack Montgomery: Who the Hell are you guys?
- Dean Winchester: We're people who know a little something about something.
- Sam Winchester: [struggling to get out of the closet] Dean?
- Jack Montgomery: Dean can't come to the phone right now.
- Sam Winchester: Jack! I swear to God!
- Dean Winchester: [Sam and Dean have burst into a woman's apartment to save her from Jack, a Ruguru. She screams] Wait! Whoa, whoa!
- [Looks around, sees that the Ruguru isn't there]
- Dean Winchester: We're here to save you... I guess.
- Girl in Bar: I'm calling the police!
- Dean Winchester: Sorry...
- [Closes the broken door]
