Gemini

S7, E9: Clark returns to Smallville from the Fortress and tells Lana that Kara (recurring guest star LAURA VANDERVOORT) is gone. Clark tells Lana they should team up to bring Lex down, so she gives him all the information she's gathered so far, including a report on a man named Adrian (guest star Tim Guinee -- "Ghost Whisperer," "Without a Trace," "Broken English"), who was infected with an alien substance. Adrian secretly plants a bomb on Chloe and tells Lois if she doesn#t get Lex to admit the truth about his experiments with 33.1, he will detonate the bomb. Chloe, thinking she is about to die, confesses to Jimmy (Aaron Ashmore) that she is a meteor freak.
