As Clark puts it on, he realizes Zor-El (guest star Christopher Heyerdahl) manipulated the whole thing and that blue kryptonite strips him of his powers, enabling Zor-El to take control of the Fortress of Solitude.
 
 “Meanwhile, Chloe (Allison Mack) and Lex (Michael Rosenbaum) each discover Lois (Erica Durance) and Grant (Michael Cassidy) have been seeing each other and warn them to stop.”
 
 The episode was written by Todd Slavkin and Darren Swimmer and was directed by Glen Winter.
