Continuity: There are several close up shots of the syringe that Dr. Hamilton is using to threaten Pete with and you can see that it is made of plastic. Clark uses his heat vision to overheat the syringe causing it to burst but the sound the syringe makes when it bursts is that of a glass syringe and not the plastic one he was actually using.

Continuity: Clark tries to talk to Pete into helping him find his ship. As Clark was talking about the driver, we see the cover to Pete's locker in the foreground. Cut to a different angle and now Pete's left hand is on the locker and it wasn't there in the previous angle.

Audio problem: Clark says "What if it's some sort of high tech crop duster or something?". Pete replies with "She'll never let us live it down." After the shot changes you can see Pete's mouth say "live it down" again with no sound coming out.

Audio problem: After Pete confronts Clark about the missing space ship in his tool shed, Pete walks away and Clark tries to explain. We hear Pete say "wait ‘til Chloe hears about this..." as he was getting into the car however, his lips were not moving.

Continuity: When Dr. Hamilton was about to pour liquid kryptonite on Clark, Pete hits him on the back and he goes crashing onto a table knocking everything on it off the table. Yet later we see an open bottle of liquid kryptonite on the edge of the table (which was cleared by the doctor earlier) dripping onto the doctors forehead.

Continuity: When Pete first finds the ship, there are only three cornstalks between it and the van. Later when he shows it to Clark, there are many more stalks. (Time)

Continuity: After Pete confronts Clark about the missing space ship in his tool shed, Pete gets into his car and we see Clark put his right hand on the door of Pete's car. Cut to a different angle as Pete drives away but now Clark's hand is no longer on the door.

Continuity: At the collision, Pete looks out over the cornfield and sees the flashing turn signal of the truck but not its headlights, which should be brighter. (Time)

Continuity: While in the line to claim their class rings, Pete holds a folded piece of paper (probably his receipt). As Clark says: "I earned that money.", Pete starts to unfold the paper. Cut to a different angle as Clark continues: "Besides, my dad said." but now Pete is looking at a completely unfolded piece of paper.

Continuity: When Pete and Jonathan corner Clark in the cornfield, Pete opens a lead box containing green kryptonite to weaken Clark. The position of how Pete holds the lead box changes every cut. At first he is holding it with just his right hand, then just his left, then both his hands.

Continuity: After Jonathan and Martha talk about Clark's new behavior in the porch, we see Lana at the Talon sprinkling something onto a drink. When Clark was still walking towards Lana we can see that the pointed part of the container Lana was holding was pointing up. Cut to a different angle and now the pointed part of the container Lana is holding is pointing down.

Continuity: During the opening scene, behind Jesse you can see the vice principal walk up behind her and reach out as he's about to put his hand on her shoulder, yet the very next shot of Lana, in the background you can see he's just exiting a room.

Continuity: 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: After the credit card company calls the Kent's to confirm purchases made the night before, we see Jonathan holding a mug by the rim. They then notice the music coming from Clark's barn and go to investigate. Cut to a different and now Jonathan is holding the mug by its ear.

Continuity: When Chloe tells Pete about her discovery about the Red meteor rocks, she gives a sample to Pete who then looks at it. At this time the red meteor embedded in the rock is above Pete's left index and middle fingers. Cut to a close up of Pete's ring and the rock but now the rock is embedded in between Pete's left index finger and thumb.

Continuity: When Clark gives his "I understand you, dad" speech at the table, he puts his left hand on his mom's right shoulder. She then holds Clark's hand with her right hand. Clark then walks across the table and as they cut to a wider angle Martha Kent's right hand is suddenly on the table.

Continuity: At the bar, the agent shows the barkeeper a picture of Jessie. Throughout the whole conversation, it is the agent who is holding the picture. However, when the agent says something about the legal drinking age in Kansas, it is the bartender who is instantaneously holding the picture.

Continuity: While Clark is talking to the agent that he has pinned to the wall, with the billiard table, the balls near the gun change their positions between shots.

Factual error: When the agent goes to the Luthor mansion and confronts Clark about Jessie's whereabouts, Clark uses his speed to push the billiard table into the agent and jams him against a wall. As he does, the billiard balls obviously move due to the force Clark put on the table. Cut to the agent and later on Clark and we still see the billiard balls on the table yet they are no longer moving. It was too quickly for an object in motion such as a billiard ball to come to a complete stop given the force Clark exerted on the table.

Continuity: When Pete and Clark go to Byron's house to find him, Clark finds the hidden locked door to the cellar. Clark then breaks the locks and uses both his hands to pull on the door. Cut to a different angle (from above Clark) but now he is just using his left hand.
