Continuity mistake: When the video of Kimmy plays on the school announcements, and she talks about Duncan being hung up on Veronica, there is a cut to Duncan reacting with raised eyebrows in the foreground, while Veronica can be seen in the background with a passive expression. Then it cuts to a close-up of Veronica having a visible reaction with her whole face falling. But since Veronica and Duncan were reacting to the same thing, Veronica's reaction should have been visible in the first shot as well.
Continuity mistake: In episode 1-12: "Clash of the Tritons," in the scene where Veronica is in her trunk, as the camera angle is on the trunk of Veronica's car, the shot right before Wallace lets her out, you can see the reflection on the trunk of Percy Daggs, III. However, the next shot is of Wallace walking up to the car.
Continuity mistake: During the diner scene with Keith, Veronica and Lamb, Lamb leaves and Veronica starts to go next. As Veronica starts to leave, still sitting in the booth, she puts on her hat (right after she says to Lamb "smell ya later"). The camera angle is on Keith, but you can barely see Veronica putting on her hat. In the next shot, the angle is on Veronica who is just packing up her books. She has no hat on, but then puts it on (again).
Continuity mistake: Deputy Leo is at the police station when a woman reports her daughter is missing, but moments later when Keith tracks Veronica to a storage/warehouse, Leo is playing with his band and doesn't seem to know what is going on and Keith has to tell him that a girl is kidnapped.
Other mistake: When Beaver takes the iPod/camera, the pictures are left on Veronica's laptop. This would only be possible if the pictures were copied onto the computer. It would have taken a considerable amount of time for all of the two thousand photos to be copied. There is the possibility that Beaver copied the three or so photos of Logan, but considering his anger, that's hardly something that he would take the time to do.
