(on the dock)
Peyton: Hey. I was kind of hoping you wouldn’t show. Jenny, you be good, okay? Take care of your dad.
Jake: Peyton.
Peyton: Look, don’t say anything. You guys just be safe.

Lucas: Look, I know you did your best, mom. If you hadn’t kept Dan away, Keith and I probably wouldn’t have been so close. And I would have hated to miss that. So I understand now why you had to keep that secret to yourself. You just needed to find yourself on your own, right?
Karen: Yes.
Lucas: Well, that’s what I want, too. To start over. I mean, that’s what you did when you shut Dan out. That’s what you’re doing by leaving town.
Karen: What do you mean, start over?
Lucas: I mean get away. Away from Dan. Away from this place. And away from all the mistakes I’ve been making. I want to go with Keith, mom. I want to leave Tree Hill.

Haley: I was over at Nathan's and I was on his computer, and I came across all this creepy porn.
Peyton: How creepy? Like she-male midgets?

Haley: (to Nathan) I can’t be Peyton for you. I can’t be those girls. I just ... I won’t.

Dan: Where’s Jagielski?
Tim: Sometimes coach lets him miss practice because of his baby.
Dan: Sounds like Whitey. There’ll be no more special treatment for anyone, understood? Now this ball control offense Whitey’s running is out. From now on it’s run and gun. Players make plays.

Lucas: So, you going to tell me what happened with Haley? I called her last night and she wouldn’t pick up.
Nathan: Let’s just say she found out I was looking at some websites that don’t exactly make me boyfriend of the year. All right, not that it’s any of your business, but um, Haley and I, we’re not, I mean she’s not, you know, so, I’m just trying not to pressure her that’s all.
Lucas: Yeah, sure. Porn freak.
Nathan: What? Shut up, dude.

Nathan: So that’s what this is? You’re worried I’m going to compare you to them when we --
Haley: Yes, I’m afraid. That’s part of it. Nathan, it’s hard enough for me to even think about being naked in front of you. And the thought that this is the standard I’m going to be held to? Forget it.

Keith: Lucas came to see me last night. He had a lot of questions about what you told him. About Dan. And he wasn’t the only one.
Karen: You have a right to be upset.
Keith: You’re damn straight I have a right to be upset! You want to explain to me how you could keep that from me all these years? I had a right to know Dan wanted custody.

Peyton: So I hope you don’t mind I had to bring Jenny along. Jake kind of asked last minute.
Brooke: Well it’s never too early to learn to accessorize, right?

(to Haley about the porn on Nathan's computer)
Peyton: You don’t have to compete with anything. You’ve got something they don’t. You’ve got his heart.

Haley: (to Nathan) I gave you my heart. That's all that I can give to you and if that's not enough for you ... then I'm not enough for you.

Lucas: So did Dan talk about me when you were little?
Nathan: Well, when I was younger I used to hear my parents argue about you. I knew you were out there. And I hated the fact so I hated you. I just thought what my dad wanted me to think. It sounds stupid but it made sense at the time.
Lucas: You know he wanted joint custody of me. That’s what he was talking about at the jail.
Nathan: Wow. I didn’t see that coming. The one descent thing the guy does and he buries it.
Lucas: So, you think if Dan would have gotten his way you and I might have grown up together?
Nathan: What would that have gotten us?
Lucas: Well, we could have teamed up against him.
Nathan: Or we could have killed each other. Trust me, man, you didn’t miss out on anything.

Episode Title: The Leaving Song

"The Leaving Song" is a song by Bloodsimple off of their album A Cruel World.

(just before Lucas leaves Peyton's after apologizing)
Lucas: I’ll be seeing you, Peyton.

Lucas told Peyton this same thing after his one-on-one game with Nathan in the "Pilot".

(Lucas shoots and misses the basket completely)
Nathan: Nice shot Haley.

In "Hanging By A Moment", Nathan helps Haley learn to shoot a free throw in order to help her pass gym class.

Karen's line to Lucas "There is only one Tree Hill - and it's your home" was added by creator Mark Schwann in response to network executives and fans inquiries as to why the series title is One Tree Hill. The series title was chosen by creator Mark Schwann after the network asked him to retitle it from it's original title of Raven. While listening to U2's The Joshua Tree, the song "One Tree Hill" inspired Schwann to change the episode title to reference the song and change the town name to Tree Hill to reflect the episode title.
