Despite Dean’s (Jensen Ackles) directive to forget about looking for a cure for the Mark of Cain, Sam (Jared Padalecki) continues to do research.   Dean suspects Sam is hiding something but decides to focus on a new murder case where they run into Cole (guest star Travis Aaron Wade).  The three team up and learn a Khan worm is infecting men and turning them into murderers.  Unfortunately, the worm makes it’s way into Cole.  John Badham directed this episode written by Jenny Klein (#1015).
