‘North Shore’ has
Doherty for 3 episodes

Shannen Doherty arrives Friday for at least a three-episode appearance on the Fox hotel drama "North Shore." Doherty plays Alexandra Hudson, long-lost sister of series star Brooke Burns. Doherty's first appearance will be the Sept. 20 episode.

The third episode of "Lost" is called "White Rabbit," featuring a 12-year-old Jack finding himself on the playground in an argument with a bully, who eventually beats him up. Jack later learns a life lesson from his father.

The adventure/drama should be using its Nimitz Highway soundstage soon; a series of caves have been built on the set.
