"Come on Crowley, that's ridiculous." Said Sam. "Lucifer doesn't share credit with anyone."

"Tell me another explanation that fits, moose." Crowley countered.

"The man has a point, Sammy." Dean agreed. "I mean think about it, Lucifer could team up with someone just for kicks and then end it last minute. That's not too big a jump."

"Okay, but who would do it?" Sam asked.

"Someone who hates you." Cas said to Crowley, who huffed.

"Right. Like that's a short list."

"We can try and narrow it down." Said Sam. " Is there anyone in particular who has been on your case lately?"

Crowley thought it over, and listed a few demons names. Using the lapis lazuli crystal, he said them each and was left with a feeling of emptiness inside. None of them were right. He sighed. What else could he do? He wished forlornly that his mother was there. She would know what to do.

"If we can't figure it out this way, maybe we can ask." Said Cas. Dean gave him a confused look.

"You really think Lucifer is going open up to us like some teenage girl in a diary?"

"If it meant selling the other person out to protect himself then yes, absolutely."

Dean looked over at his brother. "Sammy? What do you think?"

Sam shrugged. "What have we got to lose?"

Crowley was silent for a minute, then spoke. "Alright. Let's go."

He was still unsure about teleporting, but he decided to give it a shot anyways. He took all of them to a home in Lincoln Park, Michigan. The three of them looked at him confusedly.

"What, do you think I was going to transport you into the cage? I'm not crazy."

Dean shrugged and opened the door. Crowley gave Castiel that Lapis Lazuli crystal before he went in to test the truth of Lucifer's words.

There was the cage. Dean and Castiel went inside while Crowley and Sam stayed behind. Getting Crowley inside would have been a mistake, and getting Lucifer's true vessel anywhere near him would have been idiotic. The two of them waited outside anxiously as Dean and Castiel went in.

Lucifer wasted no time transporting the pair into his cage. He grinned, and Dean cringed as he saw Nick's vessel decaying.

"Well, well, well, if it isn't Dean Winchester and my little brother. You sure are a long way from home. What can I do for you today? No, wait, don't tell me: you want to find out what nefarious plan I've come up with now, right?"

"Not quite, superstar. Look, we know you're working with somebody to take Crowley down, and we just want a name." Said Dean. Lucifer put on a face of mock hurt.

"That's it? No "hey, it's been a while, how have you been?" No small talk? No etiquette? You boys really need to learn some manners."

"Just tell us what we want to know, Lucifer." Said Castiel.

"I don't do these things for free, little brother. Everything has a price."

"Fine. What do you want?"

"I want you to stop killing my children. They have work to do, just like you and our brothers and sisters do. Swear to me that you will leave them alone, and I'll tell you what you want to know."

Castiel looked at Dean, who seemed to be weighing the pros and cons of the idea. Finding a loophole in the argument, Dean nodded his consent.

"Fine, deal." Castiel said, shaking his brother's hand. "Now give me a name."

"Angus McAdams."

Castiel fingered the stone in his pocket, turning it over in his fingers. His instincts told him that his brother was telling the truth.

Castiel and Dean shared a look before nodding.

"Little brother." Lucifer called. Castiel looked back at him.

"Yes?"

"There's something you should know about Angus."

"What?" He asked, gripping the stone tightly.

"Angus wasn't after Crowley."

"Wasn't?" Echoed Castiel incredulously. Lucifer nodded.

"He was after his mother." Castiel paused, letting that sink in. His gut told him that it was the truth.

"Thank you." He said, before transporting himself and Dean out of the cage and back outside the house. Crowley took them back to the bunker himself. Then, they gathered in library.

"Well?" Asked Crowley. "Who is it?"

Castiel handed him the crystal. "His name is Angus McAdams."

Cas looked for any indication of knowing him pass through Crowley's expression, but found none.

"Never heard of him. If I had to guess I'd say he's a nobody who wants what's mine."

"Um, I don't think that's entirely true." Said Castiel.

Crowley looked at him. "What do you mean?"

"Lucifer said that he was after your mother and not you."

There was a small flickering of emotion through Crowley's expression, and then a closing in. He was silent as everyone stared at him. Slowly, everything was beginning to weave together. His transfiguration, his apparent kidnapping, and his mother's sacrifice were plotted out carefully to get the maximum torment out of his mother while ending in her execution. It was a Brilliant plan, one he might have thought of himself. He actually was surprised he hadn't thought of it. But he regretted that it came at the cost of his mother's life- just when they were beginning to get closer to one another. Then, all at once, there was complete and absolute fury. How dare this man take his mother from him?! Who the hell did he think he was, deciding that her life was one worth taking. Crowley looked at the glass sitting on the table nearby with complete, insane rage, and it exploded, shattering into a million pieces. Dean, Cas, and Sam let out mutters of protest, but were silenced when he said,

"Be glad it was the Glass and not you."

A few minutes later, he was calmer, but still quietly infuriated. Finally, he looked at all of them with an expression of determination and righteous fury.

"We have to find out his connection to my mother."
