On Thursday's new episode of Supernatural, viewers will welcome back Mark Sheppard.
The veteran actor - who has appeared on such hit shows as CSI, Leverage and Chuck - reprises the role of Crowley, a demon who first showed up in 2009 and who returns on "The Devil You Know" to make a deal with Sam and Dean.
He says he can help them find the remaining Horsemen rings so they can trap Lucifer. But, as you might expect, this plan doesn't go smoothly.
Get a sneak peek at Sheppard as Crowley in this clip, and check out the following still shots of him from this week's episode:
