Lana and Chloe are enjoying a day at the Lowell County fair when they run into a classmate, Seth Nelson, Lana's lab partner who has a crush on her. He is manning a booth at the fair where the prizes are snow globes of Smallville with bits of meteor rock in them. Chloe suggests Lana give Seth a chance, but Lana is not attracted to him, as they have nothing in common.

Lana loses the game at Seth's booth, but Seth still gives her a prize anyway, which angers another patron who lost. Seth runs away, but the patron finds him and bashes him over the head with one of the snow globes. Bits of meteor rock from the snow globe enter his blood stream through the gash in his head. At the hospital, he is receiving an MRI when the magnetic field reacts badly with the kryptonite in his blood. The machine shorts out and shocks Seth. Lana rushes to his side, and when he touches her hand, there are tiny green sparks, and Lana suddenly finds Seth attractive.


Seth Nelson receives new powers while in the hospital.

The next day, Seth realizes he can move metal objects with his mind. Clark and Lana visit Seth together, and Seth asks Lana on a date. She is reluctant at first, but when he touches her hand again, she agrees. Clark tells Lana he is fine with this, but confides in his parents that he is jealous.

Officer Mason is investigating the murder of Lionel's parents. He tells Lex that Chloe Sullivan is also investigating Lionel, so Lex goes to the Torch office to ask her why. Chloe refuses to discuss it with him, and he warns her that she is in over her head with Lionel.

Clark goes to the Talon to tell Lana the truth about his jealousy. Lana admits that she is not even attracted to Seth and is not sure why she agreed on a date. When Seth comes to pick her up, she tells him that she does not want to go out with him, but when he touches her, she suddenly changes her mind. Seth takes her to the fair. Although it is closed, he uses his power to open the gate, to Lana's amazement. Clark follows the two into the fair and mistakenly believes Lana is screaming on the Ferris wheel when in reality, she is laughing. Clark pulls the Ferris wheel to a stop. Lana and Seth are annoyed that he is "stalking" them, and they leave.


Lana and Seth decide to leave Smallville.

The next day at school, Clark approaches Seth and says he knows that Seth is controlling Lana. Clark warns him to stay away from her, but Seth is not intimidated. Clark enlists Chloe to help him look up Seth's medical records for clues about how Seth is controlling Lana. Chloe gives him a hard time about being unable to accept the fact that Lana might have feelings for Seth. The medical records reveal that Seth's electromagnetic activity is higher since the accident. When a doctor enters the file room, Chloe covers for them by pushing Clark against the cabinets and kissing him, explaining that they were just taking a break from candy striping.

Lana is waiting for Clark in his barn and says she knows about Clark confronting Seth at school. Clark tries to convince her that Seth is dangerous, but she refuses to listen. She says that who she dates is none of his business. Later, Seth convinces Lana that they should leave Smallville forever, and she agrees to get money. Lex catches her stealing the money from the register at the Talon. He tries to talk sense into her, but she does not listen to him. She rides off with Seth in a brand new yellow Mustang.

Lex tells Clark about her uncharacteristic behavior and calls the sheriff. Clark super-speeds up the road and uses his heat vision to melt the asphalt. They drive into the tar and get stuck. Seth leaves Lana, jumping onto a passing milk truck just as the sheriff catches up to arrest her.


Lex warns Chloe against investigating his father.

Chloe arrives late at the Torch to find the office has been ransacked. Officer Mason is there, but she does not call the police because then she would have to explain why he might be interested in her research. He takes her computer and leaves. She goes to the mansion and accuses Lex, but Lex denies involvement. He takes Chloe to the morgue to show her that Mason has died of natural causes. Lex thinks his father did it and he offers her his protection. She refuses.

Clark visits Lana in jail. She apologizes to Clark and says that she believes him now about Seth. She lies and says that Seth was headed to Granville. When Clark leaves, Seth arrives and breaks Lana out. He takes a guard's gun.


Clark and Seth fight.

Clark arrives home and tells his mother that Lana lied to him. Pete tells them that Seth and Lana are on the run. Clark uses a compass to find them at the carnival again. They are planning to slip out of Smallville on one of the trucks that will take the carnival rides out of town tomorrow. Clark grabs Seth and throws him across the room. Lana grabs his gun and threatens to shoot Clark. Seth takes the gun and sends Lana outside. He shoots Clark and learns that Clark has special powers, too. Seth picks up a coaster car and hurls it at Clark, pinning him against the wall. Clark grabs an electrical line and electrifies the coaster car. Seth is pulled off his feet, attracted to the car. When he makes contact, he receives a shock that puts him in a coma.

Lana receives community service for her crimes. She is genuinely sorry for her behavior, and she asks Lex for her job back. He agrees without hesitation, saying he did much worse things at her age.

Chloe goes to the mansion to accept Lex's offer. She reveals her deal with Lionel, but lies about spying on Clark. She says she was investigating him in an attempt to blackmail Lionel. She reveals that Lionel Luthor and Morgan Edge were close childhood friends.

In the barn, Lana apologizes to Clark, but admits that she appreciated that Seth was honest with her and that she wants to find another relationship like that.
