Supernatural will be heading into Season 12 with new leadership.

TVLine has learned that showrunner Jeremy Carver will step down at the conclusion of the current 11th season to focus on his new CW thriller Frequency, which earlier this week was ordered to series. He will be succeeded by the new co-showrunning team of Robert Singer and Andrew Dabb.

Singer has been with Supernatural since Season 1 as an exec producer, director and occasional writer. Dabb joined the series in Season 4, working his way up from writer/story editor to co-executive producer. Carver, meanwhile, began as a script writer on Supernatural in Season 3. He left following Season 5 to work on Syfy’s Being Human, only to return in Season 8 as showrunner.

Supernatural was renewed for Season 12 back in March.

Carver’s new series, Frequency — dubbed a reimagining of the 2000 sci-fi film — centers on a female police detective (The Flash‘s Peyton List) who discovers she is able to speak via a ham radio with her estranged father (also a detective) who died in 1996. They forge a new relationship while working together on an unresolved murder case, but unintended consequences of the ‘butterfly effect’ wreak havoc in the present day.
