Continuity: When Lex first tries to break out of Belle Reve, he stabs a security guard in the leg with a pencil deep enough to draw a large amount of blood on the guy's pants leg. But when Lex is trying to incapacitate the man you can see the pencil flopping around on the guards leg and not sticking inside the guy's leg.

Continuity: After Clark gets his powers back the cut on his cheek heals and leaves only blood on his cheek. While still at the power generator he goes to wipe this blood off of his face with the back of his hand only in the shot just before you see his hand go to wipe, a second before his hand actually appears on screen, the blood that was on his cheek is now gone as if it was already cleaned.

Audio problem: When Lex gets outside and makes a run for the gate you hear the sound of Lex running on a gravel or small stone covered walkway. However, several time we are shown his feet and he is actually running on a regular concrete walkway.

Visible crew/equipment: As Clark is ambushed inside Belle Reve, in shots focusing on Lex as he is being beaten by the twin and again a few seconds later, there is a dark object in the upper right corner of the shot. There is nothing in this scene to explain it and it moves with the camera so it is probably some piece of filming equipment. Regardless of what it is, it should not be in the shot.

Continuity: At the end of the episode, the doctor takes the mouthpiece out of Lex's mouth, then the scene cuts to Clark. When it cuts back to Lex, the mouthpiece is back in his mouth.

Continuity: Martha asks Clark to come out after he gets glasses. In the shot showing all three of them, Clark comes into view on the left side of the screen and is turned toward his parents. The very next shot shows he is just walking through the door of the optometrist and turned away from his parents as he closes the door.

Audio problem: Just before Adam says "If I read something in out friendship that wasn't there." the camera shot is focused on Lana but you can see Adam's mouth in the top left of the frame. In that shot you can see Adam's mouth is saying the line before we hear it.

Continuity: As Lana starts her second swing at Chloe with the axe while the camera is in front of Lana Chloe is just barely getting up and is still close to the floor. The camera switches in mid-swing and suddenly Chloe is completely standing and is able to jump back to dodge the swing.

Visible crew/equipment: As Chloe is running from the truck there is a shot where you can see the camera shadow on her back as she is completely turned away from the truck.

Continuity: When Molly first starts flipping through the disks for Lex, she has a ring on her left ring finger. After Lex talks about just getting back Molly is shown still flipping through the disks only now the ring is gone.

Revealing: The computer that Molly takes the hard drive from is shown as having no power cord plugged into the back of the unit. With no power being supplied to the unit the hard drive would not be displaying a picture on the monitor, the monitor itself maybe plugged up but no signal from the computer would be going to it, and we see that the wallpaper on the screen is immediately taken off when Molly unplugs the hard drive.

Plot hole: Clark looks up an old newspaper article on the Internet, citing some of the information to Chloe. Subsequently, and to Clark's surprise, Chloe reveals some additional information she has dug up elsewhere. However, that very same information was also included in the newspaper article he was reading.

Continuity: When Adam says "It's nice to be appreciated" Lex is looking at Adam. In the next shot, as Lex says "strange thing is." and now Lex is looking down at the file or piano.

Continuity: In the head on shot of the car that almost hits Mr. Altman you see the driver of that car react by turning his car to the left. In the very next shot, as Clark and Mr. Altman are just coming to a stop after Clark's high speed rescue, the driver is now turning his car to the right, as shown by which way his wheels are turned.

Plot hole: During Clark's rescuing Lana from the fire in the basement, Clark wakes Lana just before he is grabbed by the coach. Clark then tosses the coach all the way across the room and into a wall. Lana makes no mention of how Clark could toss a full grown man across a room like that even though it happens right in front of her face.

Plot hole: Outside the school, as Clark is talking to Jordan, there is a lot of people in the surrounding area. Clark looks up and sees the coach standing in the street and the car slams on its brakes to avoid hitting him, this causes the tires to screech thus drawing attention to the incident. Clark realizes that the coach is about to be hit by the car and uses his super speed to save him. Yet nobody seems to wonder how he suddenly appeared next to the coach just in the nick of time.

Continuity: After Dante says "...if you want to turn that tortoise into a hare just give me a call." he walks off and the shot follows him as he walks all the way over to a black car and starts to work on it. The shot returns to Clark and Pete and Dante is shown walking away again on the left side of the screen.

Continuity: At the start of the final race there is a bridge at the far end of the road that Pete and Jason are going to race to. During the entire race they never pass this bridge yet it ends up behind Jason's car when Pete looks in his rearview mirror as the crash is going on.

Continuity: As the two racers speed past Clark and Martha, in the truck at the intersection, Pete's red car does not have its neon lights on in the back window and under the rear spoiler. Then in the next shot, while still racing, both the blue neon lights in the back window and the green neon under the rear spoiler are on.

Visible crew/equipment: Safety bars are seen in the stunt car as it flips around and lands on the side of the road. The mechanism that is used to propel the car upward can also be seen.
