The possibly immortal Supernatural TV show on The CW is getting two new show-runners for the upcoming 12th season. Robert Singer and Andrew Dabb will take the reins in season 12. Current showrunner Jeremy Carver is leaving Supernatural, because The CW has ordered his new Frequency TV show to series. TV Line originally broke the story.

Singer has been with Supernatural, starring Jared Padalecki, Jensen Ackles, Misha Collins, and Mark Sheppard, from the beginning, as an executive producer, executive consultant, director, and occasional writer. Jim Beaver’s Bobby Singer character is named for him. It is Singer’s voice heard as the radio DJ, in season 10, episode 18, “Book of the Damned.”

Dabb boarded Supernatural in 2008 as a writer and story editor. Before this promotion to showrunner, he was working as a co-executive producer. His first “written by” credit on the series is for season four, episode six, “Yellow Fever,” with Daniel Loflin. “Yellow Fever” gave Supernatural fans this outtake (below).

Here is another gift that keeps on giving, from Supernatural, “Yellow Fever.”

Fan reaction to “Yellow Fever” prompted creator and then-showrunner Eric Kripke to write an open letter to the Supernatural fandom, explaining that he, the writing staff, and creative team did not consider Jensen Ackles’ Dean Winchester a [euphemism for male genitalia]. The letter has been broken into two parts. It is inserted into this Supernatural “Yellow Fever” recap. Kripke’s letter: part one. Kripke’s letter: part two.

Dabb has come a long way since he and Loflin wrote an episode where Sam (Padalecki) and Bobby had to road haul a ghost to defeat it and free Dean from the Buru-buru ghost sickness, he was infected with, seemingly because he was a…bully. Carry on, my wayward son.
