The hit CW/Warner Bros. action series Supernatural is coming up on it’s 6th season finale, which will air on May 20th. According to recent updates to the episode information on The Internet Movie Database, the two-hour episode titled The Haunter In The Dark has some interesting surprises in the first hour of the episode.

The first surprise in first hour of The Haunter In The Dark is that it was not only written by series creator Eric Kripke, but also lists actor Jensen Ackles as a writer as well. Ackles is best known in Supernatural as the actor who plays older brother Dean Winchester opposite Jared Padalecki who plays younger brother Sam Winchester. This isn’t the first time that Jensen Ackles has branched out his resume in Supernatural. Earlier in season six, he made his directorial debut in the S6.4 episode Weekend At Bobby’s. It’s not certain at this time how much of the first part of Haunter In The Dark that Jensen Ackles is responsible for writing, but it is a sure bet that it will be the same kind of top notch work that fans and viewers have come to expect from this talented man.

The second, and probably the biggest surprise of all, is that actor Jeffrey Dean Morgan is listed as starring in The Haunter In The Dark.  According to the information on the Internet Movie Database page for the episode, Morgan is reprising his role as  Sam and Dean’s father, John Winchester. Jeffrey Dean Morgan has gone on to become a successful movie actor since his last appearance in Supernatural in the S2.1 In My Time of Dying, in which John Winchester traded his soul into hell to save the life of his son Dean and S2.22 All Hell Breaks Loose Pt 2 in which John’s spirit rises from hell to help his sons defeat the yellow eyed demon.  While he was in Vancouver filming his role as the Comedian in The Watchmen, Jeffrey Dean Morgan did some voice over work for Supernatural for the S3.14 episode Long Distance Caller in which Dean believes he is hearing his father’s voice on the telephone.

The Internet Movie Database does not list any synopsis for the Supernatural season 6 two hour finale The Haunter In The Dark, so fans and viewers don’t know yet how the return of John Winchester fits into the episode or how the character, which has been deceased since season 2, will be brought back into the storyline. Guess we will just have to tune in on Friday May 20th at 9 PM EST to find out.
