Lucas: (opening voiceover) Sometimes it feels like it was yesterday. We graduated high school, saying goodbye. That feeling that you get at seventeen or eighteen that nobody in the history of the world has ever been this close, has ever loved as fiercely or laughed as hard or cared as much. Sometimes it feels like it was yesterday and sometimes it feels like someone else’s memory.
Haley: You're daddy loves you. You know that, right?
James: Uncle Lucas loves me.
Peyton: (voiceover) Hi, it's Peyton. Yeah, I'm sorry. I know it's late there, I just ... What happened to us, you know? I don't know who I am anymore. Or how I got here. I miss who I used to be. I wanna have a home again, you know? And real friends, you know, the kind of friendships we used to believe in. I miss that. And I miss you. I guess I just miss all of it.
John Knight: What's the name of the sushi place I like?
Peyton: You were wrong yesterday when you said the kids in the clubs were just there for decadence. I think it's more like romance and hope and inspiration. And that feeling that you get when other human beings pick up basic instruments and make sense of your world. And the day that I think it's just about making money is gonna be the day that I've betrayed everything I believe in. About music and life and myself.
John Knight: Is that a sushi place?
Peyton: I quit, John. I'm going home.
John Knight: You're making a mistake.
Peyton: No. I'm fixing one.
Peyton: Hi. How long has it been?
Lucas: Two years.
Peyton: No. It has been longer than that. Luke, I missed you.
Lucas: I have someone now. I’m with someone.
