Continuity mistake: After Emily shoots the unsub in the head and he falls on the bed, the gun falls beside him. A second later they show her walking over to his body to remove the gun from his hand. (00:51:00)

Other mistake: There is a mugshot of a 35 year old suspect on Garcia's computer. According to what she is saying, the suspect's mother died 10 years ago. A photo shows her with the suspect and he looks exactly the same age as he does now. (00:40:00)
