The cast features fifteen major roles with star billing: eleven return from the fifth season, one returns from the fourth season after a year's absence, and three are new regular cast members. Unlike the latter half of the previous season, in which the cast was divided into two groups following two separate storylines, Season Six features an alternate universe scenario which the producers call "flash-sideways," and almost all the main characters participate in both storylines. Returning from the fifth season are the survivors' leader Dr. Jack Shephard (Matthew Fox); former fugitive Kate Austen (Evangeline Lilly); millionaire Hugo "Hurley" Reyes (Jorge Garcia); former torturer Sayid Jarrah (Naveen Andrews); con artist James "Sawyer" Ford (Josh Holloway); medium Miles Straume (Ken Leung); former mob-enforcer Jin-Soo Kwon (Daniel Dae Kim) and his privileged wife Sun Kwon (Yunjin Kim); leader of the island's native population (known as the "Others") Ben Linus (Michael Emerson); and deceased crash survivor John Locke, who lives on in the sideways timeline but has been possessed in the original timeline by the mysterious Man In Black. Emilie de Ravin returns in her role as Claire Littleton, a new mother who was absent for one season after disappearing on the Island, and Henry Ian Cusick also returns as Desmond Hume, who starts the season off the Island. The new main cast roles go to pilot Frank Lapidus (Jeff Fahey), Richard Alpert (Nestor Carbonell), an ageless advisor to the Others, and mysterious Flight 316 leader Ilana Verdansky (Zuleikha Robinson). Carbonell was named a main cast member by the executive producers at Comic-Con 2009, after guest starring in the previous three seasons, and Fahey and Robinson were confirmed after appearing in recurring roles in the fourth and fifth seasons.
