A/N: So, this is my new story. I'm not quite sure how this'll turn out, but we'll see... I'm going to write a song lyric at the beginning of each chapter that basically summarizes what's going to go down in the chapter. Please, follow/favorite and review!

It's too cold outside for angels to fly - A-Team by Ed Sheeran

Dean stood outside Bobby's house, leaning against the Impala. He groaned, annoyed at the fact that Castiel still hadn't used his mojo to zap himself to Dean's exact location. He'd already been waiting for 30 minutes, and wasn't about to let the angel have any more time.

"Cas, you son of a bitch, where are you?" He muttered under his breath, looking up at the dark blue sky. Checking his watch, he saw the time was 10:30 PM. He shook his head and stepped into the car, not yet turning the ignition on, rubbing his hands against his face.

"Hello, Dean." A rough voice said. Dean jumped, turning to see Cas, sitting in the passengers seat.

"Damn it, Cas! Why didn't you come sooner?" Dean demanded, his hazel eyes deepening in color due to his anger. Castiel pondered for a moment.

"... I was busy."

"Wow, I hadn't figured that out!" Dean yelled sarcastically. He turned the ignition on, and drove away from the house, occasionally stealing glances from the celestial being. Castiel just gazed out the windshield, unsure of what to say.

"Dean, the war between Heaven and Hell will be starting soon." Castiel finally said, looking at Dean. Dean rolled his eyes.

"I know that, Cas. You don't exactly have to remind me." The hunter sighed.

The two men remained silent for what felt like the longest time. Castiel would attempt to say something, but it never went well.

Neither one spoke the rest of the ride to the motel.

Sam sat alongside Dean in the nearby diner, sitting across from Cas, who stared at his hands on his lap.

Sam would glance at Dean, then at Castiel worriedly. Something went wrong between the two, but he didn't want to ask. Eventually Dean had enough of Sam trying to decipher what was going on, though he didn't dare speak a word.

"Dean, I need to, uh, tell you... Something." Sam murmured, glancing at the angel for a moment. He looked back at Dean. When the older brother looked at his sibling quizzically, Sam took it as his chance to talk. "You'll probably get mad since I didn't tell you earlier, but..."

"But what?" Dean demanded.

"In Bismarck, North Dakota, a 17 year old girl was found sitting in the middle of the highway, at almost 11 o'clock PM. in a hospital gown. Apparently, she escaped the mental hospital she was at a mere 2 hours before she was found. She was at the hospital for Schizophrenia and Bipolar Disorder." Sam said quietly. Dean looked confused, not sure what this had to do with their area of expertise.

"What does this have to do with anything?" Dean asked, glancing at Cas for a split second. Sam's expression changed from alert to somber.

"The mental hospital she was in... It's in Florence, South Carolina." Sam murmured, keeping his voice low. Dean looked shocked; how was a Schizophrenic 17 year old girl supposed to escape a mental hospital without getting caught and manage to run 1,654 miles in 2 hours - it should take over 500 hours!

Dean had a sudden moment of realization. He looked at Castiel, who now hung his head low, though kept his gaze locked onto Dean. Sam looked between the two, not knowing what was going on.

"Cas... Was that why you were so late last night? Were you helping out a psycho chick run away from a mental hospital? Because that would explain why you were late." Cas didn't say a word. "Hey, angel, are you going to help me out here... Or no?"

Castiel waited a few minutes to answer. "Yes, I was helping her run away. But for an acceptable reason."

Dean scoffed, rolling his eyes. Sam looked at Castiel, puzzled.

"Why would you need to help a delusional girl?" Dean asked, needing to know why Cas was helping out a random girl. Castiel glared at Dean.

"The child is not delusional, Dean. Nor is she a psychopath. She was diagnosed with Schizophrenia, but she... Does not actually have hallucinations. She was raised in an Atheistic atmosphere, and she claimed she knew everything about the Christian religion's beliefs: Past, present, and future. Her parents heard her talking to 'herself'. But they did not know that she somehow could communicate with both demons and angels." Castiel explained. Sam unconsciously leaned in, intrigued by the situation. Dean leaned back against the booth, remembering what happened with Anna.

"So, she can communicate with both demons and angels, she knows everything that has happened, is happening, or will happen?" Sam questioned, wanting the angel to confirm what was just said. Castiel nodded.

"Yes, she knows everything about the past, present and future. But, only for the angels and demons." Castiel clarified. Dean's eyes widened as he heard the last statement.

"Then that means she knows who will win in the war against Heaven and Hell, doesn't she?" Dean asked. Castiel nodded.

"The demons want her as much as the angels, if not more. We need to find her before Crowley gets to her." Castiel told the hunters, making Sam forced Dean out of the booth. Dean laid a fifty dollar bill on the table, and walked out with the other two men.

When they were all sat in the car, Dean sped off, heading towards Bismarck, where the girl would hopefully still be.

They reached their destination a few hours later, arriving at a police station with their fake badges and sporting monkey suits. Cas thought it best that he stay in the car.

A young woman sat at a desk, forcing a smile. She grinned up at the boys, smirking when she saw Sam. Dean cleared his throat, making her leave La La Land.

"How can I help?" She fake-cheerily asked, widening her smile. Sam and Dean took their badges out, making the woman shift uncomfortably in her chair. As Sam was slipping his badge back into his suit, Dean started talking.

"This is my partner, Agent Rogers," Dean stated, point king to his younger brother. "And I'm Agent Novak. We need to talk to the deputy about the 17 year old girl found on the highway."

The receptionist's smile fell, and she looked confused. "I'm sorry?" She asked incredulously. Dean rolled his eyes.

"About what?" Dean sarcastically asked, Sam giving him his infamous bitch face. The elder brother cleared his throat. "I'm, um, sorry. That was... Uncalled for."

"No worries..." The woman replied hesitantly. "But, really, why is the FBI involved in this?" She questioned, still not paging an officer.

"How is a schizophrenic 17 year old girl supposed to walk almost 2000 miles in 2 hours? From where she was, it should have taken her at least 500." Sam asked, becoming annoyed with her. "As my partner mentioned before, may we please see the officer that is assigned to this case?" He asked politely. The woman nodded, walking off. She returned moments later with a man a few steps behind her.

"Agent Novak," Dean said, introducing himself, holding the fake badge out. He pointed to his younger brother. "This is my partner, Agent Rogers. We are here for the case of the 17 year old found on the highway."

The officer nodded, walking them to an office in a corner.

"So, what about this case do you need to know?" He asked, sitting down in the chair at his desk. He gestured for the hunters to sit down. "Name? Medical history? Legal history?"

Sam took a small notepad out of his suit along with a pen, nodding. "What was the girl's name?"

"Her name is Amara Winters. She was diagnosed with Schizophrenia at the age of 5 years, and Bipolar Disorder at 10 years of age. Her parents noticed her talking to herself more and more as the years went by, although she says she was 'talking to angels and demons.' She was put into a mental hospital when she was 14. She wasn't talking to her hallucinations as much. In fact, they nearly stopped." The man rambled on, Sam furiously scribbling onto the paper. When Sam was done writing, Dean looked at the officer; he obviously wasn't finished.

"But?" He prompted. The officer sighed, leaning back against his chair.

"One night, around 3 in the morning, a nurse went to go check on Amara because she heard banging and smashing coming from her room. The nurse opened the door and found two wings painted on one of the walls in dark red, with trails of the liquid running down the wall. Amara was slumped against the wall, sitting her back between the two wings. Her pants were off, and there deep, wide gashes in her legs." The officer shivered.

"So she basically sliced her legs, and painted on the walls with her blood?" Sam asked, wondering what this had to do with how the girl got to the highway.

"Yeah, she did. The odd thing was, though, that there was nothing sharp enough in her room to cut through her skin like she did. Her fingers and nails, besides being caked from painting with blood, weren't damaged in any way. There weren't any knives, there was no broken glass. No sharp metal. There was no way she could harm herself." The officer said, confusion obvious in his voice. Sam stood up with Dean, and the two nodded, shaking hands with the deputy. They parted ways after a few moments.

When Dean was about to start the car, he looked over at Cas who sat in the backseat. Castiel just stared into Dean's eyes blankly, knowing what was going to happen.

"Cas, there something' you want to tell us?" Dean asked, his tone making it clear that he wanted an answer - and now. He started the car and drove away, heading towards the motel on the quiet street.

"Amara is not schizophrenic. She does not have bipolar. Of course, though, humans cannot assume that another human is a certain way due to their beliefs. It would spark an outrage." Castiel waited a few minutes before continuing. "She... is at a constant battle with herself. She does not know who she should side with - Heaven or Hell. There is a reason though."

Sam and Dean exchanged puzzled glances before looking back at Castiel. The angel looked between the two of them for a moment before clearing his throat and continuing. "She is stronger than many angels and many demons. Her powers are... Consuming her. She has two sides: demonic and angelic. Though you two may claim that she has two personalities: calm and selfless, or sadistic and mindless."

Dean was still behind. "Care to elaborate, buddy?" He asked. Castiel rolled his eyes.

"She is half demon and half angel." Cas explained, annoyance clear in his tone. Sam almost choked on air hearing those words. Dean's hands tightened around the steering wheel, his knuckles turning white. Rain began pounding on the windshield, and Cas remained silent.

"Haven't we dealt with one before?" Sam asked, breaking the tense and awkward silence. Dean shrugged, unable to remember at the moment. The angel shook his head, fiddling with his hands in his lap.

"Sam, even if you had killed one before, she will not be nearly as easy to destroy." Castiel murmured, expectant of anger and confusion.

"Why not?" Sam asked. Castiel looked at the younger hunter and sighed.

"She's too powerful, Sam. Before you could lay a finger on her she could kill you. She could kill you with a single touch." Castiel warned, making Sam cringe ever so slightly and Dean tighten his grip on the wheel more before loosening it.

"How could a hybrid get that damn powerful?" Dean demanded, needing an answer.

"I do not know. Neither does my Father nor Crowley. No demon and no angel know. All we know is that, whoever side she is on, that is the side that will win."

"How do you know that she'll choose the winning team?" Sam inquired.

"As far as I am concerned, and according to my current knowledge, she does not have a death wish just yet." Castiel said softly, hanging his head in shame.

"Well, I say that we go to sleep and find this son of a bitch tomorrow so we can get some answers." Dean suggested. Sam shrugged and Castiel didn't respond in any way. When the three men got the motel, they got their much needed rest.

The next day was going to be a long one.
