Abandon all hope, ye who enter here.  'Supernatural' has lost yet another show-runner, but picked up a spare.  So with the series headed toward the end of its seventh season, and an eighth renewal by The CW likely, just who's going to pick up the pieces and keep the Winchester brothers riding along?

Deadline TV reports that current 'Supernatural' series show-runner Sera Gamble will step down at the end of the season, likely opting to focus on development.  Gamble had been with the show since its 2005 beginning, then a writer, taking over head scribe duties for series creator Eric Kripke after his season five exit.  By the beginning of the sixth season, Gamble also served as executive producer and show-runner for those wily Winchester boys.

While it remains uncertain precisely why Sera Gamble decided to abandon her post, the good news is that 'Supernatural' has a familiar face coming to its aid, as former executive story editor and co-producer Jeremy Carver will return to take show-runner duties.  Carver had previously left 'Supernatural' in 2010 to executive producer Syfy's 'Being Human' alongside his wife, Anna Fricke.  Fricke will take the reigns for 'Being Human' full time, though Carver will retain his executive producing credit.

Carver is perhaps best known for penning some of 'Supernatural‘s most well-received episodes, including “A Very Supernatural Christmas,” “In the Beginning,” “Mystery Spot” and “Changing Channels.”  Carver originally departed alongside series creator Eric Kripke after season five, who always envisioned the series to have a five-year arc.

Additionally, no formal decision has been made regarding pickup for an eighth season of the cult phenomenon drama, though given its solid ratings in the Friday night slot a renewal is expected from stars and fans alike.

What say you?  Has Sera Gamble's reign as 'Supernatural' show-runner ended too soon, or is it about time some new blood found its way into the ongoing tales of Sam and Dean Winchester?  Give us your hopes for 'Supernatural' season 8 in the comments below!
