 While returning home with Lois, Martha is hit by a flash of light followed by a thunder and contracts a lethal Kryptonian disease. Clark believes that Jor-El is charging for his resuscitation and asks for help to Professor Milton Fine. He discloses to Clark that Jor-El was a dictator in Krypton, who destroyed their great leader Zod first, and the planet later and sent Clark to Earth to dominate the world. Further, the salvation of Martha would only be achieved though the destruction of the Fortress of Solitude. Meanwhile, Lionel convinces Chloe to investigate Professor Milton Fine and find who he really is. When Lois, feeling offended because Lex called her of "muffin peddler", meets Chloe, the double decides to visit the LuthoCorp., where the truth about Professor Milton Fine is revealed.
