(after Nathan makes Jason walk away)
Carrie: I've never seen your jealous side before.
Nathan: You still haven't.

Peyton: I came back for Lucas.
Brooke: I know. You've had your Lucas stealing face on the moment you picked me up at the airport
Peyton: What Lucas stealing face?
Brooke: The only face you've got.
Peyton: Well, it doesn't even matter now. He's with Lindsay. If I came back for Lucas, then why did you come back?
Brooke: Duh, for Lucas. Game on, bitch!

Lucas: Why are women so screwed up?
Nathan: Let me guess, Peyton?
Lucas: How did you know?
Nathan: Because she's sending you a drink with a check in it.
Lucas: Yeah, we're having a tough time with the whole friends thing. How did you two do it so easily?
Nathan: I make everything look easy.
Lucas: Nate.
Nathan: Peyton and I were never in love.
Lucas: Yeah, well, Lindsay is mad at me, too.
Nathan: Yet you seem more upset about Peyton.

Haley: I guess one shot won't kill us, huh? (they all do the shot) Maybe it will. Brooke, what was that?
Brooke: I wanted something that would remind everyone of me, so they mixed their most popular liquor with their sweetest. The bartender did name it a "Brooke Davis". (to Owen) Isn't that right?
Owen: Actually, I think you named it that. I call it tequila and grenadine.

Haley: When are you going to grow up? This is our first time back in a bar since your accident, and already you're in another fight. Have you learned nothing?
Nathan: What do you expect me to do? Sit back while some jerk harasses you?
Haley: That's exactly what I expect you to do, because you're not always the guy that has to jump in and do something. And I'm not a damsel in distress. And if your last bar brawl didn't make it clear enough, you're not Superman.

Lucas: I asked you to marry me, and you said no, so I moved on. Why haven't you?
Peyton: Because I should've said yes.

Brooke: Tric needs to establish a "no mom" rule.
Haley: I'm a mom.
Brooke: You don't count. You got married and pregnant before you graduated high school. You'll be safely locked in a home by the time you're 35.
Haley: Good talking to you, Brooke.

(Peyton knocks on Lucas' door)
Peyton: (after seeing Lindsay teary eyed) Lindsey. I -- I'm sorry. I never wanted --
Lindsey: (showing Peyton her finger) Lucas asked me to marry him.

When Carrie does the two shots in a row, the shot glasses change location between shots.
