Synopsis by Hal Erickson
Lex (Michael Rosenbaum) is slated for electroshock therapy to erase his "delusional" memories. Summoned to the hospital where Lex is being held, Clark (Tom Welling) is determined to prove that his friend is sane before any further damage can be done. What Clark doesn't know is that he is walking into a trap devised by three of his longtime enemies. Elsewhere: While Lana (Kristin Kreuk) is undergoing physical therapy in the wake of her riding accident, she meets an affable but somewhat secretive fellow patient named Adam Knight (Ian Somerhalder), whose parents died under suspicious circumstances.
