Plot summary
Ben orders Locke to kill Cooper as part of his initiation, which he is unable to do. Richard gives him Sawyer's file and Ben warns Locke not to join them without Cooper's dead body, while he plans to kidnap the pregnant survivors. In the present, Desmond's group, mistrustful of Jack, take Naomi to Sayid. She explains that she was hired by Penny to find Desmond and a freighter is waiting offshore for her signal. Sayid fixes her radio, but finds the signal blocked. Locke returns and takes Sawyer to the Black Rock, locking him in a room with Cooper, who he realizes is the real "Sawyer".
He forces Cooper to read his letter, but when he tears it up, Sawyer kills him. Locke gives him the tape Juliet made for Ben, and when asked if he was paraplegic before the crash, Locke replies "Not anymore" and leaves with the body.
