While Clark is frozen in the Fortress, Bizarro takes over his life with Lana. Unaware that she is with Bizarro, Lana enjoys this "new Clark," and shares information she has gathered on a serial killer who is draining his victims of all trace minerals. The two conclude it must be Brainiac (James Marsters), and Bizarro sets off to find him. Lex is stunned at Lionel's reaction after Grant (Michael Cassidy) reveals he is a clone of Julian. Marc McClur, who played Jimmy Olsen in the "Superman" films, guest stars as Dax-Ur.
