Boone Carlyle was a middle section survivor of Oceanic Flight 815, and he was also Shannon's stepbrother. He attempted to assume a semi-leadership role within the faction of survivors but failed due to being rash and young, though he became Locke's apprentice when the two formed a close bond. Throughout his time on the Island, Boone would spend a lot of his time with Shannon, due to the fact that he was secretly in love with her, something which he overcame during his time on the Island. Boone survived on the Island for 41 days before he died. This was due to severe complications from injuries sustained in a fall while he tried to contact 'rescuers' from the drug smugglers' plane. According to Locke, Boone was a "sacrifice the Island demanded."
