Continuity: At the beginning of the episode when Seth is eating in the Crab Shack and talking to Ryan, he's holding his drink but in the behind shot he's bringing the drink to his mouth but in the front shot it's resting on the bench and again in the back shot he's sipping the drink but in the front shot it's nowhere near his mouth.

Continuity: When Seth and Summer are having breakfast at a cafe he pushes his toast towards her and she eats the crusts. But in the next shot, and for the rest of the scene, the plate is still beside Seth.

Continuity: After Summer calls Seth and Ryan from the bathroom to say she's found Marissa, she puts her phone on the shelf, and then goes back into the main room to find Marissa gone. Then as Summer walks out the door she shoves her phone back into her bag, even though she left it on the shelf.

Continuity: When Summer and Seth are arguing during the car trip to T.J., Summer's hands move from touching her hair to holding her bottle when she says, "You're Jewish?"

Continuity: When Marissa leaves the bar, after downing the pills and tequila, she leaves her bag, but presumably Ryan found it. Then, when Ryan sees Marissa down the alley he runs to her, but his hands are empty, yet, in the next shot, where he kneels over her body, Marissa's bag is in his hand and he puts it down beside her.

Continuity: When Marissa and Ryan are out at the vending machine, Marissa hasn't got her cell phone with her, and she hasn't got any pockets, but then later when they are heading back inside just as it rings she is holding it.

Visible crew/equipment: During the Tijuana scenes, several times during and after the scene where Marissa catches Luke, you can see the shadow of the camera on the characters.

Continuity: Jimmy brags to Marissa that he is having an "actual phone line" installed that day, when in the episode before he is seen using a cordless home phone when Julie rings him after Marissa ran away from the hospital.

Factual error: Marissa tells Ryan that she "has never slept with anyone before" (in the literal sense), which is not true as she and Ryan slept together (in the literal sense) at the motel in Tijuana, and then woke up with their arms around each other.

Continuity: When Sandy, Kirsten and Rachel walk into the living room, Rachel's arms move position between shots.

Continuity: When Marissa goes to see the psychiatrist, she sits down and puts her jacket on the arm of the chair. When the shot changes, her jacket is on the other side of her.

Revealing: If you look closely, a bit into the fight you can see that Hailey is not actually putting any trash inside the trash bag. She is just going through the motions.

Continuity: At the end of the game, when the whole group is in the lounge at the Cohens', Luke and Seth are versing each other on the PlayStation. However, the screen shows the game is only in single-player mode, but both Luke and Seth are using controllers.

Revealing: The picture of Marissa and Ryan that Oliver hides is from the pilot episode, at the fashion show hosted by Marissa. However, at the time she and Ryan barely knew each other and wouldn't have an excuse to take a photo together.

Continuity: When Oliver is singing along to "It's Not Unusual" by Tom Jones and is dumping all the pills onto the coffee table, the pills go from being all mixed up to in colour co-ordinated piles, and back and forth.

Continuity: At the start, Summer and Marissa are talking about the weekend. Summer says something like, "I'm going mad over Seth Cohen." The camera swaps from Summer and Marissa. We see Summer first with her hair in front of her ear, then when we cut back after seeing Marissa, Summer's hair has gone to behind her ear.

Continuity: Ryan walks into Oliver's hotel room twice; there are two shots of him moving from behind the hotel room to come in front of it, separated by six seconds.

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: Anna's sleeves change while she is playing video games in the student lounge.

Audio problem: The phone message that Ryan leaves on Luke's voicemail is different to what he originally said, which is "I want to make sure you took care of it. Take care of it," but the message recorded is, "I'm just calling to make sure you took care of it. Take care of it." Also the background sounds from the club - the music, people talking, etc, are missing.
