'Lost' character to make comeback

Cynthia Watros is to make a comeback to Lost for "multiple episodes" next season.

The actress will reprise her role as Libby, who was killed off in season two but still had an unexplained backstory. "She'll be in enough of the show for us to fill in the missing pieces of her story," confirmed exec producer Carlton Cuse to TV Guide. "We could not be more pleased. Cynthia is a smart and engaging actor, and [we] have some very cool parts of her story left to tell."

The news of Watros' return comes after Harold Perrineau, who plays Libby's killer Michael, rejoined the season four cast as a series regular.
