Clark rescues classmate Eric in an electrical storm. After they're both struck by lightening, Eric gets Clark's powers. Worried about the new "superboy," Clark is also confronted by Lex with proof of his superpowers.

Who is Eric Summers? (Eric is portrayed by actor Shawn Ashmore, "Bobby Drake," "Iceman" in the film "X-Men"). Eric is a nerdy student whose abusive father is also one of his teachers at Smallville High. During a science class field trip to gather rocks, Eric is saved from plunging to his death in Rockway Dam by Clark. During the save, they are both struck by lightening, and a meteor rock from Eric's bag causes Clark's superpowers to be transferred to Eric.

What's up with Clark? The next day Clark can't get Dad's work truck unstuck from the mud and gets a leg cramp from gym class. It's a big adjustment being normal! Of course the Kents encourage and support Clark as he tries to cope.

What's up with Lex? Using the resources of the sleazy newspaperman from The Inquisitor, Lex views a computer animated reenactment of the accident where Clark saved his life. Feeling he has proof of Clark's superhuman abilities, Lex visits Clark at the farm, expecting the truth from his friend. Clark takes offense that Lex investigated behind his back. Conveniently, Clark is normal now, and Lex can see that. Later, Lex decides to drop further investigation, and declares the Kents "off limits."

What's up with Chloe? In Eric's first public display of his powers, he intervenes to retrieve Chloe's laptop from a purse snatcher on the street. Witnesses on the street, including Holly, Eric's dream girl and her boyfriend Brent, see Eric shatter the purse snatcher's knife, and throw him at least 30 feet into the air. Chloe proudly gets her first byline in The Smallville Ledger when she writes an account of the incident.

What's up with Lana? Lana's wearing her kryptonite necklace again. But now that Clark's normal, it doesn't affect him. Lana notices that Clark has changed and is more relaxed, as it seems the "burden of the world" is lifted from him. She has her own problems, shocked to find out that Aunt Nell is planning to sell the building that houses her flower shop and the old closed movie theater. Lana has an emotional attachment to the theater, as it is the place where her parents fell in love.

What's up with Pete? Clark and Pete are challenged to a hoops game against Whitney and Brent. Although Clark and Pete lose, Clark is secretly thrilled at playing for the first time without having to worry about hurting anyone.

What's up with Victoria? Sir Harry Hardwick and Victoria meet with Lex to tell him that Hardwick Enterprises has purchased Cadmus Labs, a tech company that Lex says he has been researching for months. This is the same company that Victoria snooped from his computer files. Victoria and Sir Harry leave with Lex seeming betrayed and the father/daughter team feeling victorious and closer to acquisition of LuthorCorp. Later, in a second meeting of the three, we find that the files on Cadmus Labs were fiction and the company is worthless. Lex planted the information especially for Victoria to find. This leaves Hardback Enterprise open for hostile takeover by LuthorCorp. After, Lionel phones Lex to proudly congratulate his son in winning the war of deceit. After this call, the sleazy newspaperman from The Inquisitor hands Lex an envelope of surveillance photos of Victoria and Lionel in a sexual encounter. He then tells Lex it was initiated by Lionel.

How it ends: Feeling responsible for Eric's new powers, Clark tries to intervene as Eric gets in a fight with Brent over Holly. Both Brent and Clark get tossed at least 20 feet in the air by Eric, as Holly rejects him, calling him a "freak." Clark comes out of the confrontation with bruised ribs. Eric threatens his father when he arrives home. Police arrive, but Eric escapes after overturning one police car, and tossing the other into the roof of his parent's home.

Knowing he must save Eric from himself and destroying the town, Clark realizes the only way to stop Eric is by using his weakness for kryptonite. Clark borrows Lana's necklace, leaving her with a kiss on the cheek. Finding Eric at the dam, Eric overpowers Clark, throws him to the ground, and reaches for a power line. Kryptonite necklace in hand, Eric and Clark battle, the power line electrocuting both, and transferring powers back to Clark via the kryptonite.

Clark returns Lana's necklace in the lead box, to protect Lana's memories. Lana feels it's Clark's way of telling her not to wear the necklace. Clark says that he doesn't want it to hold her back. She comments "sometimes letting go is the only way to move forward," and notices Clark again has the weight of the world on his shoulders.
