Previously on The O.C.

There were definitely sparks between her and Carter. I was thinking we could help set them up.

- How did Summer take the fact that Reed's a woman? - I couldn't tell her, even if I wanted to.

I'm working with him on his comic book.

Getting rid of Caleb, I'll do it.

- I said I'd help you. - I'm gonna pay you back.

SANDY: Some girl took drugs, she passed out in the pool.

I gave them to her. I brought the drugs.

- Hungry? - No.

Me, neither.

Dude, you cannot blame yourself, all right?

All you did was give Trey a chance, and you believed in him. And it's like, look,

- whatever he did at Marissa's party, that's all on him. - The thing is, I don't think he did it.

I mean, Trey is a lot of things, but I don't know. I just don't think he's a drug dealer.

Okay, so then when the cops showed up and asked who's responsible for the girl floating in the pool,

he was like, what? "I'm an ex-con on parole. I know, I'll say me."

No. I think that when the cops showed up and went to put the cuffs on Marissa, he did what he had to do to stop them.

- What makes you say that? - I was about to do the same thing.

Yeah. Sure.

The compulsive need to rescue Marissa Cooper. It must be in the Atwood DNA.
