Complete story — includes the ending
Having joined a marijuana commune, Locke befriends an undercover cop. The leaders learn his identity and Locke confronts him. He admits that his superior saw Locke as easily manipulated and is allowed to leave. In the present, Locke returns to camp after surviving the Swan's destruction and takes hallucinogens, learning from a vision of Boone that Eko is trapped in a polar bear's cave. He rescues him, while a returning Hurley encounters a deranged Desmond, who talks about Locke having made a seemingly non-existent speech about saving their friends. Hurley informs the camp of the trio's abduction and Locke makes his speech.
