When Young Sam finishes his phone call to his father in the flashback, it is raining all around him. However, he, his jacket, and his newspaper are all completely dry.
Dean: Bobby, you're alive!
Bobby: Of course I am. Why are you on the floor?
Dean: They gave me morphine. A lot. Hey, look. A monster broke my leg.
Dean: And, uh Sam...?
Sam: (leaving for food) Yeah?
Chet: The Winchesters have trigged one of my search programs.
Chet: A shop in Montana. A day and a half, maybe two days from here.
Edgar: So why are you still talking to me?
Dean: Where's the pie?
Sam: You get cake. It's close enough, right?
Dean: Other shoe.
Bobby: Other who?
Dean: Sam. He took off.
Dean: I don't know. Nowhere good.
Bobby: Maybe he needed a little me time.
Dean: Yeah, but his me time ain't just him. For all we know, he's road-tripping with Lucifer somewhere.
Young Amy: So you going to tell me?
Young Sam: What?
Young Amy: How you kicked the crap out of those guys? I mean... no offense, but you're kind of...
Young Sam: Wiry.
Young Amy: Exactly.
Young Sam: We're always on the road. I mean, I've seen the world's biggest ball of twine twice.
Young Amy: Three times. Not that big.
Young Sam: Right.
Young Sam: You're always the new kid, and everyone thinks you're a freak.
Young Amy: Sam, you are a freak. But so is, I don't know, Jimi Hendrix, and Picasso. So am I. All the coolest people are freaks.
Amy: I'm a mortician. I know, not sexy. But... you know, health benefits.
Sam: Dean, look, how many times do I have to tell you? I'm fine.
Dean: Oh, yeah, now, you're a poster boy for mental health.
Dean: I'm sorry but it's that simple.
Sam: Nothing in our lives is simple.
Chet: You know what I find? Plain old people taste fine, but everything is better with cheese.
