Continuity: As Lana says "I was thinking the same thing but we don't seem to be very good at it." there is a camera change as she says "but". Before the change she only has the red cup on the tray but after the change, even though she didn't pick it up, she has a red and a yellow cup on the tray. The other cup was on the table and jumps to the tray between shots.

Continuity: When Chloe crashes through the bridge rails her windshield is dotted with raindrops. Just a few seconds later the blue truck hits her car from behind and now her windshield is dry.

Continuity: Lex whispers into his father's ear something about keeping secrets. At first the view is of him less than an inch away from his ear. In the next shot he's at least six inches away.

Continuity: During the flashback that happens at the Luthor mansion, the one that starts with the cup shattering on the floor, young Lex is shown peeking through a slightly cracked open door. Just after Lionel asks the nanny to give him Julian there is a shot of Lex peeking in and you can see that he has hair on his forehead. Now Lex, at this point, would have been bald, as a result of the meteor shower in Smallville for several years and would have no hair at all on his head in this flashback. In fact when Lionel finally realizes that Lex is outside the door we see that Lex has no hair on his head.

Visible crew/equipment: When Prof. Joseph Willowbrook and Lionel Luther walk down the steps of a building, talking about the possible whereabouts of Jeremiah Holdsclaw, they begin to cross the courtyard, which is bathed in sunlight. As they walk across, and eventually walk under another building, as they cross the courtyard, you can see the shadow of a large reflector board moving along with them as they walk.

Continuity: As Clark is sitting in his barn's loft his mother enters while he watches a model of the solar system. In the shot when he turns it off the large red globe, which looks to be Jupiter, stops well to the right of the model's sun in this shot. When the shot returns to Clark, Jupiter is now partially in front of the sun. Clark had not moved his hand from the off switch so he didn't move the model by hand and the model would have taken longer to make another rotation to put in that position.

Continuity: When Lionel Luthor shows Clark the video clip of Belle Reve from the episode "Asylum", Lex says "I know your secret Clark". However, in the actual episode of "Asylum" he simply states "I know your secret", without saying "Clark" at the end.

Continuity: After Lionel and Professor Willowbrook finish talking Clark shows up to talk to the professor. As they talk, while the camera is behind Prof. Willowbrook, he has bright sunshine on his suit coat. When the camera is behind Clark the light on Prof. Willowbrook's right shoulder is gone.

Continuity: When Clark sees that Jeremiah is in the loft, Clark stands up and closes the book he was reading as he says "What are you doing here?". The very next shot from behind Clark shows that the book is back to being open.

Continuity: When Lex tells Clark about Lionel finding the wire, Clark moves over to Lex and says that finding something incriminating on Lionel shouldn't be too difficult. Between shots, Lex and Clark's positions change in relation to each other.

Audio problem: After Clark asks Lana to have dinner with him, and she says it's not such a good idea, the camera shot changes so that Lana is on the right side of the shot. In that shot Lana's mouth is moving like she is talking to Clark only you don't hear what she is saying.

Continuity: As Lionel says "Good morning, Miss Sullivan." there is a camera change from Chloe's left to her right. When the camera is on the left, her left arm is down. When the camera jumps to her right her left arm is now in the middle of placing something high up on the layout board she is using.

Continuity: As Pete gets into his car the shadow from the car is extending out away from the passenger side of the car. As Pete starts to drive off, just a few seconds later, the shadow is now extending out past the back of his car.

Continuity: Just before Lex has his father arrested they are talking while Lionel sits behind his desk. In the shot of Lionel from his side of the desk there is a flat panel monitor behind his keyboard. In shots from Lex's side of the desk the monitor is gone. It returns as FBI agent Loder walks in and Lex stands up.

Continuity: While Clark and Pete are playing basketball, in the wide shot Clark and Pete, and the side of the barn where the hoop is, are in full sunlight. When the shot zooms in Clark and the barn are now in shadow.

Deliberate "mistake": When Clark is chasing Emily at light speed, Clark decides to use heat vision to knock the water tower down. The water tower shouldn't have had enough time to fall down and intercept Emily, seeing at she's travelling too fast.

Continuity: After Lionel finds out about the wire that Lex has been wearing, he sits down and tells Lex to get out. As Lex leaves, in the wide shot, Lionel drops his hands down to his lap. In the zoomed in shot Lionel's hands are up to his face as he plays with the wire. There was no time for him to make that move between shots.

Continuity: As Emily lies on the ground unconscious after being hit with the water, she is first shown lying there with her right arm bent up and her hand up by her head. After a quick shot of Clark she now has her right hand down by her side.

Plot hole: When Kara realizes that Agent Loder is listening in on the conversation, she runs out to his car to stop him. She has Clark's ability of super speed which she uses to get over to Loder's car. As she runs she ends up running through a wooden fence and you can see, through the motion blur of her movement, she neither jumps over the fence or goes around it yet the fence never gets damaged from her running through it.

Revealing: Loder gets scared and tries to get away from Kara. He takes off down the road at a significant rate of speed. Kara uses her super speed to get in front of the car. Loder has to slam on his brakes to keep from hitting her. At the speed Loder was going at he should have either skidded to a stop or hit Kara with his car. Loder is able to stop his car without doing either.
