Not Pictured

In this episode, Veronica learns the identity of the person responsible for the Neptune High bus crash.

Meanwhile, Veronica and her classmates graduate from high school, and Neptune reacts to Aaron Echolls (Harry Hamlin) being acquitted.

"Not Pictured" reveals Cassidy "Beaver" Casablancas (Kyle Gallner) as the perpetrator behind the bus crash and Veronica's rape.

The episode also features the final appearances of several characters, including Aaron Echolls, Beaver, Jackie Cook (Tessa Thompson), Duncan Kane (Teddy Dunn), and Woody Goodman (Steve Guttenberg).

Throughout the season, Veronica investigates the murder, focusing on a variety of suspects, including the Fitzpatrick family, Kendall Casablancas (Charisma Carpenter), and Terrence Cook (Jeffrey Sams) before turning her suspicion on Woody Goodman (Steve Guttenberg) after she learns that he is a child molester.

Meanwhile, Veronica previously dated Duncan Kane (Teddy Dunn), before he left with his baby daughter (whose mother was one of the bus crash victims) for Mexico.

In addition, Aaron Echolls (Harry Hamlin), the murderer of Lilly Kane, Duncan's sister, was acquitted of all charges.

Veronica talks to Wallace (Percy Daggs III) about Jackie (Tessa Thompson) leaving.

Alicia Fennel (Erica Gimpel) tells Veronica that Wallace has left for Paris to track Jackie.

Aaron and Kendall (Charisma Carpenter) are on the couch in his hotel room, and while she is in the shower, Clarence Wiedman (Christopher B. Duncan) appears and shoots him in the head, killing him.

Jackie meets Wallace and tells him that she had to go back to New York, where she is actually from, in order to care for her two-year-old son, whom she left with her mother, when she came to Neptune to reconnect with Terrence.

However, Bell played a prank on Muhney, telling him that she knew the killer was going to be Loretta Cancun, a minor character from the pilot.

"[6] Kyle Gallner, who plays Beaver, did not know that his character was going to be the murderer until just before the shooting of "Not Pictured", when one of the costume designers told him about the reveal: I had no idea up until right before we shot the episode.

[7] The episode also features the final appearance of Harry Hamlin as Season 1 antagonist Aaron Echolls after the character is murdered by Clarence Wiedman (Christopher B. Duncan).

Later, we learn that the murder was ordered by Duncan Kane (Teddy Dunn), who appears briefly in a small cameo.

Dunn had made his final regular appearance in "Donut Run" and had left the show partly due to fan dislike of the character.

[28] Digital Spy listed the episode on an unranked list of the five best Veronica Mars episodes, writing that it "has its issues" but that "the rooftop sequence with Veronica, Cassidy (Kyle Gallner) and Logan is pure, gorgeous melodrama, and Keith's fake-out death feels devastating instead of cheap thanks to Kristen Bell's gut-wrenching performance.
