Neptune High Class of 2006 graduation! Veronica, Wallace, Mac, Logan, and the rest of their classmates graduate from high school. Except Weevil-who is arrested by Sheriff Lamb mere moments before walking across the stage at graduation-and Dick Casablancas--who failed his science project in the episode "I Am God" and has to attend summer school in order to graduate.
Keith catches Woody Goodman, who insists he didn't cause the bus crash. Veronica proves that he is innocent (of that crime) after she learns that Cassidy Casablancas was on his Little League team. She puts the pieces together and realizes that Cassidy blew up the bus to silence Peter Ferrer and Marcos Oliveres.
Everything comes to a head at the Neptune Grand Hotel, where Cassidy threatens Veronica with a gun before secrets come out and he commits suicide.
- Weevil is arrested at graduation for the murder of Eduardo "Thumper" Orozco.
- Veronica finds a picture of Woody's Little League team and discovers that Cassidy was on the team but not included in the picture. She calls Cassidy's friend Hart Hanson and finds out that when they filmed their war movies, Cassidy was in charge of explosives, which he got from his dad's mechanic, "Curly" Moran.
- Veronica texts Mac to tell her stay away from Cassidy, but he intercepts it and texts back to Veronica as Mac to meet him on the roof. On the roof, Cassidy points a gun at Veronica and she figures out that he killed Curly Moran because Curly had figured out Cassidy was responsible for the bus crash and then wrote Veronica's name on his hand to divert attention.
- Veronica also figures out that Cassidy raped her at Shelly Pomroy's party two years ago; he got chlamydia from Woody Goodman, she got it from him.
- Cassidy detonates a bomb in Woody's plane, killing all on board. Veronica briefly thought Keith was on the plane, but Sheriff Lamb had Keith removed from the plane at the last minute, saving his life.
- Veronica is able to send a text message to Logan and he arrives on the roof and tackles Cassidy. Veronica is able to get Cassidy's gun, but Logan talks her out of killing him.
- Logan tries to stop Cassidy from jumping from the roof of the hotel by shouting "Beaver, don't!" But when Cassidy asks "Why not?" Logan cannot think of anything to say so Cassidy jumps off the roof, killing himself.
