"What Is and What Should Never Be" is the twentieth episode of the
paranormal drama television series Supernatural's second season, and was
first broadcast on May 3, 2007. Dean Winchester (Jensen Ackles) finds
himself in an alternate reality after a confrontation with a djinn. The
creature appears to have fulfilled Dean's greatest wish: that his mother
had not been killed when he was a child. Dean is happy until it becomes
apparent that his previous work as a hunter of supernatural creatures
has been undone. He then rejects the alternate reality and attempts to
bring himself back. The episode was written by Raelle Tucker, and marked
the directorial debut of series creator Eric Kripke. It featured the
return of deceased characters Mary Winchester (Samantha Smith) and
Jessica Moore (Adrianne Palicki, pictured). Kripke enjoyed expanding
upon the character of Mary, who was only briefly depicted in earlier
episodes. Despite obtaining low ratings, the episode acquired positive
critical reviews, praising Ackles' performance and welcoming the return
of Smith and Palicki. Tucker also received a Constellation Award for her
work on the episode.
