From ABC:

    This season, Jack's mistrust of Locke will grow as he continues to question his motives and obsession in uncovering the secrets of the mysterious hatch. The fates of Sawyer, Michael and Jin will be revealed after their raft was blown out of the water by "The Others" - who at the end of last season kidnapped Michael's son, Walt. Sun will become less dependent on husband Jin and more autonomous, as she wonders whether he is still alive. Kate's back-story life as a fugitive will continue to be explored. Charlie will become even closer with Claire and her baby, Aaron, but the stash of drugs he found in a statue could seduce him back to a dark life of addiction. The cursed numbers that turned Hurley's life upside-down before the crash will continue to haunt him as he begins to uncover their meaning. Shannon will decide where Sayid fits in her life while she continues to grieve over the death of her brother, Boone, and develops a growing sense of unease about the raft passengers and their fate. In addition, we discover that there is at least one more previously unknown survivor of the crash of flight #815 - Ana Lucia (Michelle Rodriguez, "Girlfight," "The Fast and the Furious") -- the mysterious woman Jack met at the Sydney airport bar.
