 The writers were supposedly scheduling an appearance by Furlan for the fifth season, but Furlan did not end up making an appearance.However, she returns in the form of Rousseau's "sideways" counterpart (who never crashed on the Island, lost Alex or went insane) in the sixth season.In a review of the first-season episode "Solitary", Chris Carabott of IGN commented that Rousseau appeared to be more emotionally fragile than in later seasons, and was like a "loose cannon".
