Libby (Lost)

Libby is a fictional character on the ABC drama television series Lost, which chronicles the lives of over forty people after their plane crashes on a remote island somewhere in the South Pacific. She is played by American actress Cynthia Watros. The character is first introduced as a member of the tail section survivors in the second season episode "Everybody Hates Hugo", together with Bernard, and she ends her role as a "living character" in the episode "?". Reception towards the character is generally positive, especially after her death, although controversy exists due to a traffic violation by the actress that plays her. While no surname was given for the character in the show, a clip reel of deceased characters at Comic-Con 2009 presented her full name as "Elizabeth Smith".

Libby appeared in twenty-four episodes, twenty-one of them in the second season, one in the fourth, and twice in season six in "Everybody Loves Hugo" and the finale. As of the end of the third season, she is the only main character not to have a centric episode that details her past, though a brief flashback at the end of the episode "Dave" is shown from her point of view. She was supposed to return during the third season, but did not make an appearance. Her first appearance after the second season was in the fourth season episode, "Meet Kevin Johnson".
