Audio problem: After they get the spaceship into Pete's shed, Pete wants to go tell Chloe. Clark insists that he doesn't and Pete says "To her, this thing is the Holy Grail.". The shot zooms in and Pete's mouth shows him saying "Holy Grail" again even though he already said it and you don't hear the words.

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.

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.

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.

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.

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 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.

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.
