Kathleen O'Neill is a Middle section background cast, who some fans believe correspond with the character Joanna Miller, due to a resemblance to a brief photograph on a burning passport in "Born to Run". In support of this conjecture, O'Neill has not been positively identified in the background of scenes after Joanna's death in "White Rabbit". However such an appearance on a prop would not necessarily signify a canoncial storyline correspondence of O'Neill with this character by the Lost writing team.
