Continuity mistake: At the beginning, a St Louis couple has reported their son missing. At the FBI briefing, the agents are told that the boy's mother tucked him in at 10:00pm. A few minutes later, we hear the radio call over footage of police at the home, and the dispatcher says "Last seen at 2100." That's 9:00pm, not 10:00pm.
Continuity mistake: While Reid's asleep in the hospital bed, Garcia places four Doctor Who figurines (one Dalek we don't see her place) on the overbed table - two Daleks, Matt Smith's Doctor, and David Tennant's Doctor. In the first shot Garcia's holding Smith's Doctor in her right hand and Tennant's Doctor in her left hand, but in the next shot those two figurines have switched hands.

Continuity mistake: The unidentified subject is cutting a piece of flesh with a fork and a knife. The first shot shows him holding the fork with his left hand. His elbow is up, index finger straight, resting on the back near the head of the fork, the other four fingers wrapped around the handle. Next shot shows him elbow down, holding the fork with all his fingers wrapped around the handle.
