Plot hole: When Dawn enters Clark's body, she slaps Chloe in the face with the back of the hand, and Chloe goes flying. A few minutes later, we see Chloe get up and say that she's fine. Getting backhanded by Clark would make you very far from fine. First of all, Clark can knock someone out just by tapping them on the forehead, as seen in a previous episode. Second, Dawn has no idea of Clark's powers, so she would have used way more force than she actually needed to. The amount of force inflicted from the attack should have caused fatal injuries to Chloe. There's not even a cut or bruise or anything.Knever
Continuity mistake: When Clark is faced with Nathan Dean at the Auto Wrecking lot, Nathan says "In a minute, neither one of you will care," (regarding Pete Ross' whereabouts). The next shot is of the blue car that Pete is trapped in with the windows blown out. Then the shot goes back to Clark and Nathan, and the cars fall onto Nathan. Clark is then listening for Pete and when we see a shot of the blue car being crushed, this time we see the windows being smashed.
Revealing mistake: As the helicopter that Lana is in dodges the falling meteors in mid-air, the camera shot focuses in on the cockpit. If you watch Lana's position as she first starts to appear she is semi-transparent and the frame of the window behind her is visible through her body.
Continuity mistake: During the scene when Jonathan comes home from the hospital the length of rolled up sleeve on Jonathan's left arm changes between shots. As Jonathan says "Low sodium turkey?" the sleeve is down to just about touch the watch he is wearing. When the camera jumps to Jonathan's left side, as Martha turns around, the sleeve is now several inches higher and further from his watch than it was before. Jonathan does nothing to his sleeve between shots.
Continuity mistake: At the bar, the agent looking for Jessie calls the barkeeper. He then proceeds to fold a piece of paper and puts down the pen which he was holding onto the bar. Cut to a different angle (as he takes out a photo of Jessie from his coat) but now the paper is unfolded and he is holding the pen in his hand again.
Continuity mistake: When Clark arrives late for school in Lex's car, he is stopped by principal Reynolds who tells him that he should have been there four minutes ago and points at his watch with his right hand. Cut to a different angle but now he is pointing at Clark with his right hand.
Continuity mistake: Seth fires at Clark and Clark dives behind a ride car to dodge the bullets. As Clark stands up he brushes the impacted bullets off of his shoulder. Seth says "Looks like I'm not the only one with special powers." before he turns to use his powers to pick up a ride car that is behind him. As Seth starts to get the car in the air, in the background you can see Clark is only just standing up and brushing his shoulder off again.
Continuity mistake: As Lois and Clark talk about her leaving, Clark turns to talk to her. Before he turns around the shoulder protector is between his hand and his shoulder and the red side is facing out. In the next shot, even though he made no motion to alter the position, it is now fully on his shoulder with the black side facing out.
Continuity mistake: When Martha is in the kitchen and starts having a coughing fit from the toxin, she drops the pitcher of lemonade. The pitcher lands on its side and breaks, but in the next shot, the broken base is positioned upright, sitting level on the floor, the jagged broken edges waiting to impale Martha.
