At around 5 mins 11 seconds into the episode, Vincent Nigel-Murrey and Dr. Saroyan are discussing the bones on the forensic platform. In the background of a shot of Vincent, the x-ray on the screen is of Homer Simpson's head in the middle of the screen, instead of a real human skull.
Continuity mistake: When Angela asks to see the girl's drawing, in the shot from the girl's perspective as she hands the pad over, the painting's quite small in the centre of the page. When it then cuts to Angela's point of view it takes up nearly the whole page.
Continuity mistake: Booth and Brennan arrive at the crime scene in the beginning of the show. After she has confirmed that the bones in the trunk belonged to a woman, a black car drives by and shots are fired. At first, the trunk of the car is less than halfway opened. Cut to the next shot and the trunk is fully opened.
Continuity mistake: When Booth and Brennan are speaking with the widow explaining that her husband was murdered. Brennan has her arms folded across her chest, when the shot changes and you see her in the mirror her arms are hanging down at her sides, then when it changes back her arms are folded again.
