Smallville - Season 1 Episode 15

After stealing an experimental flower laced with meteor-rock pollen from Dr. Steven Hamilton, the employee of the Luthor Corp, James Beales has a truck accident on the road and is rescued by Jonathan Kent. However, the flower releases its pollen on Jonathan's face, and he unleashes his innermost repressed desires first with Martha and his anger towards the Luthors. He enters in coma later. Then Lana becomes affected and tries to seduce Clark. Pete also becomes affected by the Nicodemus flower in the same way. While Clark helps Lex track down the source, Lex hides from Clark that Dr. Steven Hamilton is working for him, but they find the cure in an old book.
