Continuity mistake: Clark tells his parents that he went to see his grandfather and that he asks to give the cashiers check to his mom. He takes it out of his pocket with his right hand and Martha Kent takes it with her left hand. Cut to a different angle but now it is Martha's left arm which is see being pulled back to her body as if she took the check using her right hand instead.
Continuity mistake: At the Talon, Clark tries to write his essay when Crissy shows up asking Clark to sign up for the decorations committee. Crissy holds her clipboard with her left hand and places her right hand on her hip. But in the next shot Crissy's right hand on the clipboard as well. Cut back to the previous angle and her right hand is back on her hip.
Revealing mistake: In the Talon when Crissy is talking to Clark, we see a close up of her hand aging. However, as her hand ages, a reflection of her real hand (which supposedly aged) can be seen on the metal clip of her clipboard, which is still young and smooth, and not aged.
Continuity mistake: When Russell shows Crissy the lighting on the stage, we see him put a blue filament on the light with both his hands. He then drops his right hand as they cut to another angle but now he is lowering his right 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: When Lex finds Clark in the Talon doing his essay, he sits and talks with him. He puts his cup on the table and puts his hands in front of him. In the next shot, Lex now has his arms crossed in front of him on top of the table.
Continuity mistake: Clark rushes to get to school in Lex's car and we see principal Reynolds closing the gate to the school. In the close up, we see that the principal is off to the left of the lock of the gate. Cut to a different angle (his back to the camera) just as Clark arrives in Lex's car but now he is standing in front of the gate lock.
Continuity mistake: The "Go Crows" sign Lana is working on changes depending on the camera angle. From the front you can see the! at the end. In the close up shot of the sign, the! is now gone. When Lana underlines "crows" it's back but the writing is slightly different.
Continuity mistake: When Chrissy kisses Troy in the beginning on the episode, it takes him a few minutes to age and die. Later in the episode, she kisses Russell and in a matter of seconds he is old and gray.
Suggested correction: When she kisses Russell, she kisses him longer than she did Troy. We even see him age faster the longer she kisses him, indicating the length of time she spends absorbing someone's youth, the faster they age and die.
Continuity mistake: When Jonathan runs up to Lex, while he is unconscious, the first shot of Lex has his arm bent but not near his face. The shot switches to look down on Lex and now he is laying with his hand considerably closer than the previous shot.
Continuity mistake: When Lana shows Chloe the picture of her mother and Henry Small. We see that Chloe holds the picture on its bottom corners with both her hands. Cut to a close up of the picture but now she is holding it in the bottom middle of the picture. Cut back to the previous angle and she is holding it by the corners once again.
Continuity mistake: When Lex comes to after being kidnapped by Rachel, she wipes his face with a piece of cloth using her right hand. She then transfers the cloth to her left hand and continues to wipe Lex's face. Cut to a different angle as she says "I bought it with the money your father gave me" but now the cloth is instantaneously back in her right hand.
Revealing mistake: As Sheriff Ethan pulls up there is a reflection on his driver side window. You can see the police department shield on the door and the door handle reflected on the driver's side window. There were no other police cars there so it was probably reflected off a mirror used to help light the scene.
Continuity mistake: In the flashback when the Kent's meet Clark, we see Jonathan loading the space ship onto the back of the pick up truck. He then see Martha carrying Clark who was wrapped up in a blanket. At first we see that Martha's left arm is wrapped around Clark's back onto his shoulder. Cut to Jonathan's viewpoint and now Martha is just supporting Clark and her left arm is no longer around Clark.
Continuity mistake: Lionel press conference about Lex's kidnapping only infuriates Rachel. She then picks up an axe and was about to swing at the tied up Lex when he manages to get his right leg free and kick Rachel backwards. As she falls backwards, we can see that she drops the axe off to her left side. Cut to a different angle but now the axe is over her head to her right side.
Continuity mistake: As Jonathan and Martha drive away in the truck, we see Rachel for the very first time and she has both her hands in her coat pockets. Cut to a close up but now her hands are outside the coat pockets.
Continuity mistake: The woman uses her right hand to get a swab for DNA testing from Clark. At first, we only see her right hand near Clark's face. Cut to a different angle as she says "There, now that didn't hurt a bit did it?" but now her left hand is close to Clark's face.
Plot hole: Mayor Tate and Lex have a discussion about bribes and Tate says this is his 4th term (near the end of the episode, Lex is showing Mayor Tate an attack ad which is saying Tate has been the mayor for the past 12 years and Smallville can't afford another 4 years of Mayor Tate, so it's been 12 continuous years). In last season's episode "Crush", Pete gets a job as a summer intern on Mayor Spiegel's re-election campaign. So how is it possible for Tate to have been on his 4th term when in the previous year Spiegel was Mayor?
Continuity mistake: Nell meets up with Lana to talk to her about moving to Metropolis. We see Lana going up to Nell while riding a horse. She then stops and is about to dismount when they cut to another angle but now Lana is dismounting yet again.
