Continuity: At the beginning of the episode when Sarah is put in the police car, she falls onto her side. In the next shot, she's sitting up straight, with no time to move.

Continuity: When Cameron protects John from Cromartie in the classroom, she is shot several times, but remains standing. In the following shot, she is suddenly lying on top of John to protect him, without ever having fallen.

Continuity: As the FBI agent shows his ID to Dixon, it is in his right hand, the badge end up. He holds a folder in his left hand. The camera cuts away for just a moment, then returns to show the ID in his left hand, badge to the right, and the folder is in his right hand, all without enough time to make the switches.

Continuity: As Cromartie is approaching the Dyson home, he carries an automatic rifle with his right arm. As he makes a turn toward the left, he lowers the rifle down to his side, pointing it at the ground. He hears a car start and an instant camera angle change shows the rifle is still pointed forward and upward, not down, with no time for the change.

Plot hole: During the fight at home, Cromartie is shot by Sarah three times. He then returns about a dozen rounds as she ducks behind a flimsy, cloth-covered reclining chair. Such a chair, routinely constructed using a square wood frame around padding and springs, would offer no protection from the bullets, yet Sarah is unharmed.

Character mistake: When Dixon arrives to find Derek lying on the table with a serious gunshot wound to the chest, he immediately begins giving Derek chest compressions - without doing even the most basic assessment of Deker's condition, verifying whether he is breathing or even has a pulse. Dixon is a trained Emergency Medical Technician, not a passing samaritan. His error is against the most basic rules of his profession.

Continuity: As Cameron is questioned about the girl that commited suicide, the interviewer holds a photo of one of the mostly-black posters. When we see his view of the photo, the white letters spell 'DAN', but before and after that shot, when we see his face, we can see through the photo, and it only reads 'A', which is a different poster seen earlier in the same episode.

Continuity: As the scene begins, we are looking through Cameron's eyes as she holds up a photo of a night cityscape framed by plants. She lowers the photo to reveal she is standing in the exact spot that the picture was taken. In both the photo and her view, the plants that frame the distant city are very well lit. But the shot changes to show Cameron turning to face camera and we see the plants are now in near-total darkness beyond her.
