Seizoen 7

When Clark's cousin Kara arrives on the scene, Clark advises her to keep a low profile and master her powers, but Kara has other ideas and becomes the focus of Lex Luthor's powerlust. And, there are two Clark Kents: one is the young man whose life in a tiny Kansas town sets him on destiny's path. The other is a Bizarro who shares Clark's DNA, but not his values. Lane makes a career leap and Chloe Sullivan finds that balancing a meteor power with a personal life isn't easy.
