Chloe learns that a doctor, Dr. Curtis Knox (DEAN CAIN - Superman on "Lois & Clark: The New Adventures of Superman"), has been treating meteor-infected people and eliminating their abilities. Desperate to get rid of her power, Chloe makes an appointment to see Knox, unaware that he has a nefarious plan to kill his patients and harvest their organs. Meanwhile, Kara (recurring guest star LAURA VANDERVOORT) cons Jimmy into helping her locate her crystal and, after discovering its whereabouts, defies Clark's order to stay on the farm. And Lana sets up secret surveillance of Lex.

It's Clark's first day at the Daily Planet with Lois, and the pair are immediately thrown together on a story when a bus explodes outside the office. Clark rescues Bette (guest star JESSICA PARKER KENNEDY - "Another Cinderella Story," "Kaya"), a young girl who bonds with Chloe over their shared meteor abilities, but Bette is hiding a big secret. Paramedic Davis Bloom (series star SAM WITWER) arrives in Metropolis and is drawn to Chloe.

It's Chloe and Jimmy's dream wedding day, but two unexpected guests crash the party. Plus, Clark goes looking for Lex -- and finds Lana (former series star KRISTIN KREUK) instead.

After hearing the voice of his biological mother, Lara (recurring guest star HELEN SLATER), calling for help from Kara's (recurring guest star LAURA VANDERVOORT) crystal, Clark releases Lara, despite his Kryptonian father's warnings. As Lara and Clark reunite, she gives him a ring of blue Kryptonite. But when Clark puts it on, he realizes that Zor-El (recurring guest star CHRISTOPHER HEYERDAHL) has tricked him -- blue Kryptonite strips Clark of his powers. Now, Zor-El can take control of the Fortress of Solitude. Meanwhile, Chloe and Lex each discover that Lois and Grant (recurring guest star MICHAEL CASSIDY) have been dating and warn them to stop.
