Continuity: At the end of the confrontation between Clark and Ian regarding what he is doing to Chloe and Lana, Ian turns to his right to walk away from Clark. Cut to a different angle and now Ian is turning to his left as he walks away from Clark.

Continuity: When Clark lifts Lana back onto the bridge, from a shot from above, we see that Lana puts her left leg onto the bridge into a sitting position. They then cut to a different angle but now both her legs are still dangling and she eventually puts her right leg on the bridge first.

Factual error: When Ian throws the unconscious Chloe over the edge of the dam we see her falling down as Clark falls with her. However, Chloe's body position is unnatural for someone who is falling while unconscious. Her head/body is arched backwards when air resistance should have forced her body to become level/straight.

Continuity: The shot with Ian pulling Lana out of the car shows the shadow cast on the bridge covering half the road. A few seconds later, after Chloe gets free of the Ian that has her, the shadows on the bridge are much shorter.

Continuity: At the Talon during Chloe's interview with Ian, Ian holds the mug by its ear, but in the next shot Ian is no longer holding the mug by its ear but by the mug itself.

Continuity: When Ian is dragging Lana towards the dam, his double can be seen in the background dragging Chloe. The double is on Chloe's right side pushing her. Cut to a close up as Chloe says "Ian you need help" but now the double is behind Chloe and is pulling her.

Revealing: When we see Ian split, his two selves are supposed to be looking directly at each other but they're really both looking slightly to the right. It's hard to focus when there's really nothing there.

Continuity: After Clark catches Chloe, he runs back on top of the bridge and we see Ian with both his hands on the railing of the dam. But in the next shot it is his arms which are on the railing, then his hands once again, in the next shot.

Continuity: When Ian confronts Mr. Frankle about his grade, the teacher removes both his gloves and is about to raise his face protector. Cut to a different angle but now he has his right glove back on.

Continuity: Chloe's mouth changes from open when she hits the ground struggling with Ian to closed when he is moving her unconscious body.
