Why have a spy when you can have the King captured, interrogated and killed? Lola does more than spy on Crowley. Crowley's desperate enough to seek any help he can. Including using his new-found humanity to call for a certain angel. But what happens after that? AU from 'Blade Runners'

Michael and Lucifer's plan has come full circle, leaving Castiel and Crowley scrambling, and stuck with a bunch of dead or dying Vikings...What comes next? The deck is stacked, and the house always wins. Doesn't it?

There were several things that happened while Sam and Dean were being held in the government facility that Cas and Mary never told them about. Like that time they worked a case with Crowley and Cas almost died. Set S12 somewhere during the events of "First Blood" (Gen) Major Cas!whump

Castiel and Crowley run into a rather mundane problem while searching for Lucifer.

Crowley and Castiel investigate another possible lead in their search for Lucifer. Crowley laments a poorly made cappuccino.

A mad fire, an iron pole and pain. Whoever said being a witch was always fun was deadly wrong. AU, post season 11, somewhere between 12.

In their search for Lucifer, Castiel and Crowley stumble upon a monster hunting both humans and demons. As if working with the King of Hell wasn't irksome enough, now they have to team up against a wicked hag who has a few pointed tricks up her sleeve.

The 'Season Finale' of Castiel and Crowley Season 1! Can Castiel, Crowley and their assembled team stop the Angel and the Demon from taking over Heaven and Hell? Or is there one final, devastating twist left for our heroic C-Squared? (you just know that there is, right?) Hang on, dear viewers, the End is here...

TFW wakes up stranded in the mountains with no idea how they got there, or that the baddies of the supernatural world have had enough and are planning on making the Winchesters and their wayward angel pay for everything they've done. And there might as well be some bloodthirsty fun involved—such as booby traps, battle rounds…and the occasional hellhound. Let the games begin.

When an angel leaves a vessel, it leaves a little bit of grace behind. So when Amara ripped Lucifer out…what did that mean for Cas? With the Devil's cancerous grace eating away at Castiel's, can the Winchesters find a way to save their angel? S12 one shot

Sam thought he was being so witty when he cursed Crowley with a 'sweet revenge' for his part in the whole 'Demon Dean' debacle. So how come it's Dean that suffers?

Sam gets abducted and Dean is frantically searching for him. He seeks Cas and...Crowley's help...Azazel is back, and after Sam. Could this be the reason for Sam's disappearance?

Crowley wakes up to find himself powerless and trapped in a mental institution. It will take all his cunning to get out before the Winchesters arrive to put an end to him once and for all.

Is there such a thing as down-time in the fight to save the world? Castiel and Crowley are going to at least give it a try.

Rowena wasn't supposed to be strong enough to bind a demon and an angel, nor banish them to another dimension. But that's exactly what happened. Now Cas and Crowley will have to work together if they're going to survive and find a way home.

Showdowns with the bosses, new projects and 'market research'. Office politics in Hell is never quite as boring as it sounds - it doesn't quite get the point across...Now all Crowley has to make sure of is that the actual point isn't going across his throat...

It's been a hard week for the Demon Crowley...why can't he keep a thought straight in his head? And why is he in trouble with his boss? (Prelude to Castiel and Crowley: The Next Missions, Episode 7: Life of Crowley)

The Portal to Purgatory has been ripped open, the past, present and future are thrown into complete chaos, and Castiel and Crowley are facing down a horde of unstoppable evil...hm...must be Thursday...

Castiel and Crowley are flung back through time to a city that exists only in legend and myth...what were the Angels protecting there? And what was it that caused it to sink beneath the waves?

In their free time, they bonded over machinery. Whether or not this was ever a good idea is still unknown. Certainly nothing too bad can happen. Post-canon.

So what happens after Death himself is killed? Sam and Dean would sum it up as "a mess". And everyone - angels, demons, Reapers, Fates, even the King of Hell! - expects *them* to fix it!

A spin-off from Supernatural featuring the team of Castiel and Crowley. Following the events down south, the duo head north to Baltimore to check out a possible Croatoan outbreak. And possibly some better hotel accommodations... For Episode One, please check out: /s/10892640/1/Castiel-and-Crowley-The-Next-Missions

'When I was young - okay, younger - I thought monsters were real. What kid doesn't, y'know. Vampires, werewolves, zombies, that kind. Just waiting in the dark to get you. Then I realized that those were just people. People are the things that people should be afraid of. And now it seems like maybe there is something in the dark after all.' Sequel to Boulevard of Broken Dreams.
