The boys got the call around 10pm. Castiel was frantic, so instead of trying to get him to explain everything on the phone Sam and Dean decided it was best if they all got together and sat down to talk about everything as a team. The boys jumped into the Impala, drove through the night and met up with Cas at Emma's home.

"When you say biblical, are you talking fire and brimstone? Or a 40-day flood biblical?" Something got her angel all up in arms and the only thing she got out of him was biblical. That was after Sam and Dean arrived. Now if we were being honest. Up until Emma found out Castiel was an angel, she was an atheist and the idea of something being biblical felt a little ridiculous.

"Alright. From the beginning. What happened?" Sam asked calmly.

"Demons aren't our biggest threat anymore. Someone… something is trying to release Lucifer from the cage." The angel's gaze slowly falling on Sam given his complicated history with the Devil. "They are collecting human souls to do it."

Looked like Dean's warning was coming true sooner than the shop keeper thought. Emma fell quiet letting the trio speak amongst themselves until..."Wait, as in the Devil?! Why would anyone do that, God cast him out for a reason. " She may not have grown up to be the good catholic her parents wanted her to be, but she still remembered her readings from Sunday School.

Castiel turned towards Emma giving her a sympathetic look. This was a terrible time for the truth to come out, but it was better sooner rather than later. He was just glad she could hear it from him rather than someone else who wasn't a straight shooter when it came to facts "That's the thing Emma. God. Isn't in charge anymore. Heaven is self-governed now."

The brunette turned to look at Castiel listening to what he was telling her. With a dead pan expression "That's pretty messed up. I'm making coffee."

"Right?" Dean throwing in his two cents. "I'll definitely take some of that."

"Cas, how did you learn this?" Sam asked.

"When I was waiting outside for Emma. I was approached by another Angel. Serenity. She thinks it's a Grigori. Given the amount of souls it takes I would suspect she's right but that's not all of it. To complete the ritual. They need the grace of a fallen angel and the soul of an incarnated angel? Whoever is doing this . They are killing angels. My guess to keep them from talking."

"Son of a Bitch."

"Grigori? Like angels who fathered giants, Grigori?" Emma questioned. She remembered more than she thought.

"Yes." Cas smiled. He had this sense of pride. Beautiful, smart, and kind? How lucky was he to have Emma? "For a long time, heaven thought they had died out. But a few years ago, we faced one. I guess there are more out there than we thought."

Dean and Sam stayed, perusing the books she had on the occult. Emma ordered Pizza for everyone. The boys had to have been starving after their travels. It was surreal, really. Being thrown into the world of theirs as quickly and as bluntly as she had been. The young woman half expected to wake up from it, and just resume life as normal. Life before Jimmy Novak, before Castiel, before any of this. But she didn't want to. There was something inexplicable about the angel, and as dysfunctional as it was, something comforting about his two companions being as fiercely loyal as they were. The group found themselves finally seated around her modest table, fishing pizza slices from the boxes. The brothers were busy coming up with theories, most of them including the idea of killing first and asking questions later. But Emma's mind kept going back to the ingredient list. A soul. Of an angel? How was that even possible?

"So…" Emma began as she leaned to her left to pick up a slice of pepperoni. With a small sigh, she continued. "What did she mean by the soul of an incarnated angel? How does that even happen?" Dean shrugged, his mouth full of food as Sam swallowed his own bite. Clearly, he was the politer of the two brothers. "Well according to Christian scripture . An incarnated angel. Is...was an angel that left heaven and was reborn as human." He helped himself to another slice. Placing his plate down next to Castiel. The angel looked at him quizzically before looking at the pizza. " The lore says characteristics are youthful appearance, show great kindness and compassion towards others. So that narrows it down out of 6 billion people."

"Would someone who once was angel remember?" The young woman asked curiously.

"There have been some cases…" Sam replied as casually as he could. Only one incident came to mind "Said person is still human. Think of it as other forms of incarnation where you die and reborn as something else. Angels need grace. If the person somehow got grace back, then they would be an angel again."

Castiel picked up the slice of pizza and sniffed it, making a face of disgust and repugnance. Molecules smelled weird. "The only known one was Anna. Angels don't typically give up their grace willingly." He pushed the plate away from him closer towards the center of the table and leaned back in his chair. "Even I know better than that."

"Is being human that bad in Heaven's eyes?"

Sam and Dean exchanged looks before glancing over at Castiel who cleared his throat uncomfortably. The angel reached out and caressed her hand with his own, thumbing her soft skin gently. "Some think so. When an angel falls it's usually as punishment." He gave her hand a squeeze and she looked up at him, a somber gaze stuck in her eyes. He smiled, "I think humanity is better. But I can better protect the people I care about having my grace."

"Okay, so how do we find this person to help them? I mean, if the bad angels are on the hunt, then how do they even know? It sounds like any decent person has the potential of being one?"

Once again, it was Sam that was the first to speak up. "We can't there are six billion people on this earth, and only one is our potential angel. The odds aren't good."

"Unless, by some miracle, this person falls at our feet." Cas added.

Dean took a long hard swig of his beer and sat back. "We're screwed."

"Your problem is that you don't have any patience, or faith apparently. You have an angel as a best friend. You'll come up with something"

Sam could only laugh as Dean just looked at the woman with a face of shock and bewilderment. Castiel nodded in agreement with her words. "I've been telling him this for years."

Dean frowned, his face wrinkling up in defiance to Emma and Castiel's words for him. Apparently, he had been through this multiple time before and didn't have the time or the patience for it tonight. "Enough about me, alright? You know, Cas, your prime pickings for the fallen angel criteria." Castiel only shrugged, completely unphased by that notion. Clearly, he had already thought of that. "Not the first time someone tried to kill me."

Those words hit Emma hard. She opened her mouth to protest but silenced herself. Of course, someone would have tried to kill him. Hell, someone tried to kill him right in front of her just a month or so ago...Angels. Demons. Good. Evil. It's what their entire creation entailed. It shouldn't be a shock that he had lived through it a time or millennia. As dinner finished up, Sam and Castiel took it upon themselves to clear away the clutter as Emma and Dean watched on. He seemed so protective of the other, and she couldn't help but sense an awful amount of responsibility just oozing from him. "Cas is very lucky to have you two, you know. Not everyone is lucky enough to have someone as caring as you, in case no one told you lately."

Dean nodded and scoffed a bit, looking at her before shaking his head. He was trying to maintain that cool, indifferent act, but it was getting harder. "We're the lucky ones." That Emma could agree to. She smiled, watching as Sam try to re-center her floral vase as Castiel petted her cat "Then I suppose I'm the luckiest, since I'm getting distinct vibes that you are all a package deal."

That caused a smile to escape from the man as he looked at her. "Yeah, sorry."

Their conversation didn't continue after that, as the other two men finished up with their work, and Dean barked at them to get a move on, work needing to be done at the bunker. Emma watched them pile into the black Impala and continued watching as they pulled away, driving off into the distance. A yawn escaped her lips, as she finished turning off lights and went to bed.
