Continuity mistake: When there is a flashback of the shooting, the police officer is heard to fire 3 shots, yet in each other flashbacks it's 2 shots and there are only 2 wounds in the victim.
Continuity mistake: When Ian confronts Mr. Frankle about his grade, the teacher removes both his gloves and is about to raise his face protector. Cut to a different angle but now he has his right glove back on.
Continuity mistake: 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 mistake: After Clark finds out that Ryan is dying, we see him holding a comic book in the farm. His dad then arrives and he turns to look at him. He places his left hand to his side as he holds the comic book in his right hand. Cut to a different angle and now both his hands are together in front of him.
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 Lex has the envelope and pulls it away from Lana as she grabs for it, the flap is opened, so the wax seal is on top. In the next shot the flap is folded down.
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.
