It appears at least one of Supernatural‘s many finale deaths will stick.

Mark Sheppard will not return to the CW drama as a series regular for Season 13, TVLine has confirmed.

Sheppard first hinted at his departure Tuesday night via an Instagram post: “So to all my #spnfamily everywhere… my crew and my fellow storytellers… thanks for the ride. Time for something new.”

Sheppard’s frenemy character Crowley — who recurred for several years before the actor was promoted to series regular in Season 10 — sacrificed his own life during last Thursday’s finale in order to seal the rift between worlds.

Supernatural returns this fall on The CW, where it will continue to air Thursdays at 8/7c.
