"I was able to secure this sigil which should prevent Dagon from possessing you husband. You should also ward your property with it." Castiel said handing it to Delores. "It was suggested that you, Garth and Dean be warded with it just in case."
"Sounds like this is some serious mojo." Dean said.
"It is an ancient sigil belonging to Lucifer from the days before the Angelic Wars."
"Whoa! You expect us to use the devil to ward ourselves?" Dean asked. "No way!"
"It predates Lucifer's fall, and should not have any of the corrupted energy associated with the devil. This sigil is of the Archangel favored by our father." Castiel said. "Lucifer detested Kemuel's connection to the Leviathan at the time this sigil was used."
"Still, we're talking about Lucifer!" Dean said.
"Dean, I don't think you have grasped the fact that Lucifer is helping because he hates the Leviathan more than he hates humanity." Castiel said.
"The enemy of my enemy is my friend?" Sam said. "So what once we get rid of Dagon and the Leviathan threat he'll turn on us?"
"I believe that father's decision to place Gabriel in the cage is so that Lucifer may learn tolerance for you through Gabriel. Gabriel has become your champion among the Archangels. His time on Earth has resulted in in a growing affection for your species." Castiel said.
"So how come you didn't include Sam when you said we should ward ourselves?" Garth asked.
Castiel hesitated for a moment. "As I explained to Dean earlier, Sam's soul is...tainted."
"What? Tainted what the hell Cas?" Sam said. "After everything I'm still some demon blood infected abomination to you guys?"
"No, Sam. Your soul is tainted by Lucifer's grace. All souls of those who have acted as vessels are tainted by the grace of the angel that inhabited them." Castiel explained. "It does not mean that you are an abomination, simply that you once hosted an angel."
"So a part of Lucifer is still inside of me?" Sam asked unhappy at the news.
"No, he simply left a mark. It does not affect you in any way other than to announce to other angel's that you belonged to an angel as a vessel." Castiel said. "Lucifer has a prior clam on you and you are his vessel. Dagon will steer clear of you."
"But you said that Dan's soul is tainted." Delores said.
"Your husband's soul is doubly tainted by Dagon and by Azazel." Castiel said. "Azazel was once Luficer's most trusted general. Lucifer's sigil will mark his soul announcing that Lucifer has a claim on it. Lucifer is older and more powerful than Dagon."
"So Dagon won't want to tangle with Lucifer." Dean asked.
"Lucifer is the only that Dagon will still fear." Castiel explained.
"That makes sense except for one thing. Lucifer is locked in the cage." Sam said.
"This is true but it does not diminish the influence that he has outside of the cage. The actions of Dagon and Lilith should be proof of that." Castiel said.
"Like John Gotti." Garth said. "Running the Gambino crime family from inside his prison cell."
"An accurate description." Castiel nodded.
"Son of a bitch." Dean exclaimed. "So as much as I hate it. We have to accept the devil's help."
"You are also being helped by Michael and Gabriel. None of the Archangels wants Dagon to continue running loose." Castiel pointed out.
"Okay so what do we have to do?" Dean asked resigned.
"We should have a back up plan." Lucifer said as he turned from the television to face Gabriel. "Remember the trick I taught you that used to drove Michael batshit?"
"Get that idea out of your head right now Lucifer." Michael ordered.
"Come on Mikey it always worked on you." Lucifer said. "And we all know that Dagon could very well ignore that sigil if he thinks that I'm powerless."
"You are powerless, you're stuck in here." Michael pointed out.
"But Dagon doesn't know the extent of what I can do." Lucifer argued.
"You do realize that It's been eons, right?" Gabriel jumped in. "T-Rex was still eating Brontosaur tartar for breakfast the last time I did that."
"Which means you're woefully out of practice." Michael said.
"It's not like we don't have plenty of time to practice stuck in here." Lucifer pointed out. "If it comes down to it, having little brother here pull a Luci might be the one ace in the hole we have left to play."
"I did fool you more than once Michael." Gabriel said. "And it's not like Dagon knows exactly what Luci is like after all this time."
"He's going to reason that my time in the cage changed me as much as his time in Purgatory." Lucifer said. "And Gabriel does still have his powers."
"If Father finds out he will make sure that you both regret it for centuries to come." Michael said.
"He won't find out, and if he does we're just trying to avoid being bored." Lucifer said.
"What is this?" Dagon asked looking at the woman the fallen had dragged in front of him.
"Look closely at her Dagon, she is not what she appears to be." The fallen told him prompting Dagon to get close enough to really study the woman.
"Well, well this is a surprise." Dagon said. "Tell me, how does a pagan goddess end up with the scent of an angel clinging to her? You would have had to be very close to that angel."
He leaned forward and sniffed inhaling deeply. "I know the scent of that grace as well as my own. We would lay next to each other for decades just watching the parade of life and death on this world."
Dagon took a step back and glanced around the room with a smirk at the handful of fallen gathered around him.
"Brothers, I believe we wasted a lot of time and effort looking for him when we should have just hunted for a Hindu slut."
The dark skinned woman glared malevolently at Dagon.
"Little pagan, you have no power over me. But you will help me. You stink of Gabriel." Dagon said.
"I know of no one called Gabriel." Kali spat.
"No? Well my brother did tend to hide behind masks. You won't mind if I just check and see if perhaps he was hiding behind one of his masks when he marked you with his scent like a dog urinating on a tree."
Dagon placed a palm on either side of her face forcing himself into her mind. Kali realized that he was much stronger than she was. She also realized that the bloodspell she had placed on Loki was still there. She severed the connection quite a bit more brutally than necessary but by doing so she prevented this corrupted angel from using it against Gabriel.
Dagon enraged at having had a way to locate Gabriel snatched out of his hand, twisted Kali's head snapping her neck. He released her and snarled "Pagan whore!"
Gabriel was concentrating on Lucifer's grace when he suddenly gasped. Michael reached out and grabbed him as his vessel collapsed unconscious.
"Gabriel!" Michael lowered his brother onto the couch.
"What the hell?" Lucifer reached out with his grace only to realize that the vessel was empty. "He's not in there."
Michael looked around the cage. "Where is he?"
