Mitchell was later named the lead actress on V in an ABC press release and various sources reported that she would guest-star in Lost's sixth, final season.Mitchell's character was killed off in the sixth season premiere, but returned for the two-part series finale for which she received a nomination for the Primetime Emmy Award for Outstanding Guest Actress in a Drama Series.
