"The Substitute" is the fourth television episode of the American Broadcasting Company's sixth season of the serial drama television series Lost and 107th episode overall. The episode aired on February 16, 2010, on ABC. It was directed by Tucker Gates and written by executive producer Elizabeth Sarnoff and producer Melinda Hsu Taylor.[2] John Locke is the character the episode is centered on.
In 2007, The Man in Black, while impersonating John Locke (Terry O'Quinn), attempts to recruit James "Sawyer" Ford (Josh Holloway) and reveals the survivors' purpose on the Island. Meanwhile, Jacob's (Mark Pellegrino) bodyguards, led by Ilana Verdansky (Zuleikha Robinson), decide to bury the corpse of the real John Locke. In the "flash-sideways", Locke, still using a wheelchair, deals with the difficulties of his life.
