Walkabout (Lost)  "Walkabout" is the fourth episode of the first season of the American drama television series "Lost". The episode was directed by Jack Bender and written by David Fury. It first aired on ABC in the United States on October 13, 2004. The episode centers on the character of John Locke (Terry O'Quinn), who in flashbacks is revealed, in one of the first plot twists of the show, to be paralyzed from the waist down as he attempts to join a walkabout tour. On the present day events, Locke leads a hunting mission after the wild boar in the jungle as the food supplies of the Oceanic 815 survivors starts to shorten, while other survivors decide to burn the plane's fuselage. John Locke's backstory was conceived during the writing of the previous episode, "Tabula Rasa", and director Jack Bender decided to shoot the flashbacks in a way it enhanced the contrast between Locke's life before and after the crash. Problems involving the usage of real boar caused the producers to use computer-generated replacements and shots that suggested the animals' presence. "Walkabout" was watched by 18.16 million people and was reviewed positively, later being considered one of the show's best episodes. In the aftermath of the crash of Flight 815, John Locke awakens on the beach. He lies on the ground dazed for a few moments, wiggling his toes, before Jack calls him over to help him lift some wreckage off another survivor. Before the crash, Locke works a dull office job at a box company, where he is constantly belittled by his manager. He is planning on going on a walkabout in Australia, and has been training and studying for the trip for some time. He tells his plans to "Helen," a woman he is supposedly in a relationship with, on the phone. He invites her to come on the walkabout with him, but Helen is in fact a phone sex operator to whom he's grown attached. She breaks off the conversation. Later, in Australia, one of the walkabout guides refuses to let Locke join, saying that he is too big of an insurance liability and had not properly informed them of his "condition." Locke insists that he's lived with his "condition" for four years and that this is his "destiny," but the guide denies him. Locke is shown to be using a wheelchair. Locke's first awakening on the Island is shown once more, revealing that when he woke up, he realized he could walk again.
