S6E4 · The Substitute

Locke is fired for missing a conference with a successful Hurley. He refers Locke to his temp agency, where he and Rose Nadler bond over their handicaps and she gets him work as a substitute teacher. He admits to his fiancée, Helen Norwood, that he missed the conference to attempt a walkabout. On the island, the Man in Black encounters Sawyer and asks both him and Richard to help him leave. Richard refuses, warning Sawyer that the Man in Black wants to kill them all. The Man in Black takes Sawyer to a cave where names with corresponding numbers are written on the walls, with Locke, Hurley, Sawyer, Sayid, Jack, and one of the Kwons matching Hurley's numbers. The Man in Black claims that Jacob manipulated their lives to put them on Flight 815, and Sawyer accepts his offer to leave the island together.
