Boone Carlisle (Ian Somerhalder) is one of the survivors of the Oceanic Flight crash on "Lost." He is a wealthy young man who works in his mother's wedding business empire. Boone is used to getting what he wants and being in charge.
Boone was traveling on the flight with his step-sister, Shannon (Maggie Grace). He had gone to Australia to bring Shannon home after she supposedly suffered trouble in a bad relationship. Boone wanted to rescue Shannon because he was in love with her. The bond they shared as step-siblings makes this awkward, and he is eventually rejected by Shannon. Unfortunately for Boone, she still continued to use him to rescue her from any difficult situation, which he allowed because of his feelings for her.
After being stranded on the island, Boone grows frustrated that he is not seen as an important leader among the group of survivors. He watched Jack (Matthew Fox) and John Locke (Terry O'Quinn) take the leadership roles, and he envied them.
Boone volunteered to go hunting for wild boar with Locke. When they discovered another plane wreck in the jungle, hanging from the top of a tall tree, he climbed up to retrieve the transmitter from the cockpit. In doing so, he brought the plane crashing down, and suffered severe injuries. Locke carried Boone back to camp, where he later died, despite Jack's best efforts to save him.
"Have you been using that wacky paste stuff that made me see my sister get eaten?"
"Hate to break it to ya, but the ocean is not going to take your gold card."
"I know you made a promise, but I'm letting you off the hook. Let me go, Jack."
