Missing Episode: The episode "Imprint" was never aired in the U.S. While it dealt with a lot of subject matter that American TV censors would find abhorrent (incest, prostitution, birth defects, child molestation, and abortion), it did eventually get released on DVD. An alternate interpretation holds that Showtime deliberately withheld "Imprint" from broadcast so they could publicize the DVD set as having a "too squicky for Showtime" episode.
