After Jodi (EMILY HOLMES), the wife of a Special Forces soldier, explodes a pipe bomb in one of Lex's secret laboratories, Lionel is severely injured, and Lex is taken hostage by the enraged spouse. Claiming Lex kidnapped her missing husband, Jodi threatens to blow up the entire laboratory with Lex inside it unless he tells her where the soldier is. Clark sets out to rescue Lex but is immediately felled by the Kryptonite lining the earthen walls. Lex and Clark realize that the only way they will make it out alive is by helping each other.

Clark and Lois discover a spaceship belonging to Kara (recurring guest star LAURA VANDERVOORT), the mysterious young woman who recently saved Lex. But before Clark and Lois can open it, Kara appears and knocks Lois unconscious. Clark is shocked when Kara tells him she is there to protect baby Kal-El. Kara left Krypton as a teenager, simultaneously with the infant Clark, and has unknowingly been in suspended animation ever since crash-landing in the dam, so she is now younger than him. Despite Kara's arrival, a despondent Clark decides that, without Lana, there is nothing keeping him in Smallville, so he heads to the Fortress of Solitude to begin his training. However, Jor-El tells him that Kara's father, Jor-El's brother, was evil, and Kara must be watched closely. Clark must stay in Smallville to find out why she came to Earth. Meanwhile, Lex makes a stunning discovery regarding Lana and Project 33.1.

Zod continues to pose as "The Blur" and asks Lois to investigate one of Tess's secret labs. An explosion rocks the lab, and Lois is rescued by John Corben (guest star BRIAN AUSTIN GREEN) who was a subject of multiple experiments. While investigating the explosion, Clark is exposed to red kryptonite. And the infected Clark takes Zod to the Fortress. Tess urns to Chloe for help – and they send in Corben to stop Clark from revealing all his secrets.
