Visible crew/equipment: When Claire runs away from Bob after he calls her "Ms. Bennet", you can see Bob's shadow and another person's shadow on the ground. Since no one else was standing next to them, it has to be a crew member, most likely a camera man based on the odd shape of the shadow.
Continuity mistake: The door to Dexter's apartment opens out toward the walkway. However, in all subsequent episodes the door opens into his apartment.
Continuity mistake: After Vinnie completes his lifetime of tests, Rocket proceeds to mark them and tells him that he failed some tests but that he passed his Art "with a lovely rendition of the Mona Lisa." When Rocket is seen holding up the paper and when the camera shows Vinnie sitting at the desk explaining what he actually drew, the tick on the paper is different between the 2 shots. (00:07:15)
In Too Deep - S1-E23
Continuity mistake: When Ms. Chatham is at Emma's house, she puts her hand on Cleo's arm. It's not there in the next shot. (00:10:35)
Bargaining - S1-E5
Continuity mistake: When the guy at the restaurant dies he falls behind the broom, but an instant later he is in front of it.
Lilly, Do You Want to Know a Secret? - S1-E1
Continuity mistake: In the cafeteria, when Oliver joins Miley and Lilly at the table the food and trays change position, particularly the milk carton. Then when Oliver stands up and announces that Lilly has the two tickets, suddenly the apple has changed trays and the juice box and milk carton are lying flat.
The Head, the Tail, the Whole Damn Episode - S4-E15
Visible crew/equipment: The scene where Gus is smelling for the first shark and Shawn is 'divining' it. As they round the corner at the dock, a camera and some randoms are visible down the alley for a few seconds. (00:19:00 - 00:23:50)
Factual error: Gay pride flags are visible in a window. The 6 color flags shown were introduced in 1979 (though an 8 color flag preceded it in 1978). (00:30:44)
Suggested correction: Ms. Chatham's hand is barely visible in the next shot but it's there.
The fact that it's barely visible (as seen in the screenshot) confirms the mistake. It's on her arm and then it's not on it, she's just barely touching.
