《迷失》荒岛迷情

　　
　　Season two: 2005–2006
　　Season two began airing September 21, 2005. The story continues 44 days after the crash. Several new protagonists appear, including the tail-section survivors Ana-Lucia Cortez, Libby, and Mr. Eko. Also introduced are Desmond, a man calling himself Henry Gale, and other inhabitants of the island. The existence of the DHARMA Initiative and its benefactor, the Hanso Foundation, is established: they may be responsible for the strange occurrences on the island.
　　
　　Story elements 故事要素
　　There are several recurring story elements on Lost, some of which drive central plot points, both on the island and in the flashbacks of the survivors, while other elements provide a deeper understanding of the story.
　　
　　Black and white 黑与白
　　The colors black and white, which traditionally reflect opposition or dualism, appear frequently throughout the series, often brought together in reference to characters whose natures are presented as ambiguous or contradictory. This dichotomy is laid out in the "Pilot" with John Locke's description of backgammon to Walt: while holding up a black and white piece, Locke says, "Two players, two sides — one is light, one is dark." In the opening sequence of "Raised by Another", Locke appears as an ominous image in Claire's nightmare about her unborn child, with one eyeball black and the other white, playing with corresponding, similarly colored cards.
　　
　　
　　Other appearances of the colors likewise connect characters in apparent opposition to themselves, or each other. In "Deus Ex Machina", Sawyer, one of the more ethically questionable characters, develops headaches due to farsightedness, diagnosed by Jack and cured by Sayid, with the creation of a custom pair of glasses from the frames of two different sets: one side white, the other black. In the closing scene of "Collision," Jack and Ana Lucia, ostensibly the leaders of their respective factions, stand facing each other, with Jack wearing a white shirt and Ana Lucia wearing a black shirt. In "The Long Con", when Sawyer is telling the group that he has the guns, Jack and Locke — who were just arguing with each other — are wearing opposing black and white shirts.
　　
　　At other points, the colors are featured in sometimes unexpected or unexplained ways. In "House of the Rising Sun", Jack finds a pouch on a pair of mummified corpses, nicknamed "Adam and Eve" by Locke, containing one white stone and one black stone Urim and Thummim, which he then hides from Locke.
　　
　　The numbers 数字
　　The numbers 4, 8, 15, 16, 23 and 42 appear throughout the series, both in sequence and individually. They were broadcast from the Island's radio transmitter, and it was this message that drew Rousseau's expedition there. Although she later changed the message after the deaths of her team, the numbers had also been heard by other people, eventually making their way to Hurley, who used them to win the lottery. However, after his win, a series of misfortunes began to happen to those around him, leading him to believe the numbers are cursed. His search for answers led him to Australia and, through the crash, to the island itself, where he ultimately discovers the numbers engraved on the hatch. Inside the bunker, the same numbers appear on the occupant's medicine bottles, and make up a code that must be entered into the computer. The sum of these six numbers, 108, has also become significant in connection to the DHARMA Initiative. This number appears on a mural inside the Initiative's Station Three, and the full sequence of numbers must be entered into the computer every 108 minutes. The individual numbers also appear frequently throughout the lives of the survivors, both before and after the crash.
