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.

Continuity: Ryan and Theresa are walking along the beach with ice creams. The amount of ice cream changes between shots. This is especially noticeable with Theresa's ice cream.

Continuity: When Sandy first picks up Ryan, we see in several shots that Ryan's bike is in the trunk, and that the trunk is open. However, when they drive up to the house, the trunk is now closed, with no bike.

Continuity: In season two, episode "The Return of the Nana", Marissa's arms change position repeatedly while she and Trey are down at the beach. Also, her bag appears with her, even though she left the apartment without it.

Continuity: Early in the episode, Alex tells Seth that the night of the Killers concert is her night off. (She works at The Bait Shop, the concert venue.) At the end of the episode, Alex is paying The Killers, as if she were the manager on duty. Submitted by DavidK93

Continuity: In this episode Seth, Ryan and Kirsten arrive at the country club in the Range Rover to get the boys ready for Cotillion. In the next scene we see Sandy with the surfboards in the back of the Range Rover as he has just come home and Jimmy arrives to apologise, soon after we go back to the country club where Seth and Ryan are trying on jackets and meet up with Marissa, Summer and Luke, proving that the Range Rover should still be there, not back home.

Continuity: When Ryan is lighting Marissa's cigarette with his, at the start of the shot it's full, then the shot goes to Ryan and it's still full.

Continuity: When Kirsten and Ryan are talking while setting up for the Casino Night, the camera cuts between Ryan And Kirsten while they talk.
