Deliberate mistake: Lindsay is not at Caleb's funeral in the last episode of season 2, "The Dearly Beloved". It's unlikely that she would have missed it - she is still on good terms with him and he is her father, the only reason she left was to be with her mother, not because she didn't love Caleb.Obviously they didn't want to create another drama with having Lindsay there while they had to focus on the important story-lines - Caleb's death, Kirsten's drinking and Marissa shooting Trey.

The SnO.C. - S2-E5
Continuity mistake: In Series 2, Episode 'The SnOC', we see Zach punching Seth with his right fist. However, when Summer gives him some ice, he covers his left fist with it (which is now bruised and swollen).
Kirsten: Is everything okay?
Seth: Hmm? Yeah, it's fine.
Theresa: I'm pregnant.
Seth: Well, except for that.
The Rescue - S1-E8
Trivia: Seth is surprised that Summer has read the book "Madame Bovary". She explains that it's the favorite book of patient Tom Shales, who is incontinent (lacking normal voluntary control of excretory functions). Tom Shales is a Washington Post critic who blasted "The O.C." in his review.
Question: When Ryan goes to Marissa and Alex's apartment (after Alex told him to stay away from Marissa), he says, "If you have to work this hard, it isn't working." What does he mean?
Answer: He means that if Alex has to go so far as to forbid Ryan from seeing Marissa in order to maintain her relationship with her, their relationship obviously isn't working.
