Tonight, we get answers to two of the most hotly debated questions in primetime television.
First, just what will they find at the bottom of that hatch when "Lost" (8 p.m., ABC) returns for season two? A retrospective clip show (7 p.m.) precedes the season opener to refresh fans' memories and inform newcomers.
Second, over on NBC, we get to see just what kind of "The Apprentice" (7 p.m., NBC) host Martha Stewart can become. In tonight's opener, the 16 contestants break into two teams to try to concoct a children's book that will please the domestic diva. Will viewers flock to see Stewart in primetime? Can she concoct a signature sendoff to rival Trump's "You're fired!"?
