Clark decides that he is ready to start his training at the Fortress, but Jor-El insists that he return to Metropolis to cut his ties with Lois before he begins. Lois reappears in the city with no recollection of vanishing, and her investigation into a monorail crash brings her into contact with a new reporter named John Corben... who is opposed to the Red and Blue Blur. Meanwhile, Chloe's friendship with Clark deteriorates when he refuses to use the Legion ring to save Jimmy; Oliver turns down a dark path, and Zod makes his entrance at the Luthor mansion.
