Profession: Ballet instructor
Pre-Crash: Shannon's father died in a car accident and her stepmother cut off the funds that were previously deposited into Shannon's account. Shannon won a prestigious internship to the Martha Graham Dance Company in New York, but her stepmother wouldn't help her financially and said that Shannon's father would have wanted her to take care of herself.
Boone tried to get some money for Shannon, but his mother knew what he wanted the money for and didn't give it to him. Shannon wanted to move in with Boone in New York until she could get on her feet. Boone said she couldn't because his mother offered him a job and he was moving from New York.
Shannon hooked up with different men, each time telling Boone. Boone then bought them off thinking he was helping Shannon, but it turned out that Shannon was scamming him in order to get the money she felt she deserved.
One man, Bryan, scammed Shannon, leaving her with nothing. She had to depend on Boone and, alone in the hotel room, they slept together. Then Shannon said she wanted things to go back to the way they were. The two of them got on Flight 815 to return to the U.S.
Island: There is a lot of tension between Shannon and Boone, especially after Shannon shows interest in Sayid. Boone begins hanging out with Locke, and Shannon helps Sayid translate some French maps.
Shannon and Sayid begin a relationship, but Shannon is upset when Sayid doesn't believe that she saw Walt, who should not have been on the island. She tells Sayid that he will leave her once they get rescued, but he says he will never leave her.
They hear whispers and see Walt, and Shannon runs after him. She is accidentally shot by Ana-Lucia and dies after 48 days on the island.
