Finding the Line

Supernatural AU: For years now, Sam and Dean Winchester have been hunting monsters. Sam, driven by the ghost of his dead fiancée, and Dean, driven by the need to follow in their father's footsteps.

When will they find the line they cannot cross? When the world of angels and demons collide, Sam and Dean must choose how much they are willing to sacrifice for the life.

Sam woke up with a gasp. His heart rammed against his ribs, and sweat trickled down his brow. His mouth tasted like pennies, coppery and dry.

His mind was still filled with the images he had seen and heard in his dreams; blood dripping from a pale, limp hand, an invisible hellhound snarling viciously, and something dark and large looming in the shadows, more terrifying than any monster he had ever faced...

He lifted a hand to his face, rubbing the sweat from his eyes. He released a long breath, trying to regulate his heart rate.

His other hand automatically went to the other side of the bed, searching, feeling...

And then he remembered.

It was empty, had been for months now. Ever since...

His throat constricted. Jess...

He turned onto his side, punching the pillow into submission. He closed his eyes, and tried not to think about the new images and smells going through his mind; the fire, the image of a blonde pinned to the ceiling, and the smell...

Sam shuddered, falling back into an uneasy sleep.

Dean sat in the kitchen with a cup of cold coffee sitting untouched in front of him. He was still, ears trained for the muffled noises coming down the hall. Every now and then, he winced when he heard a shout or cry.

His brother's nightmares had been going on for weeks now, leaving Sam tired and withdrawn. Dean had found himself unable to sleep as well, tense from the sounds of his brother's screams.

Dean's hands fisted. He felt helpless, and he wished to God he knew what to do to help his brother. But for the first time in a long time, he didn't know, he didn't know a damned thing, and Sam was... He was...

The cup shattered against the wall, having been thrown across the room by an angry sweep of Dean's arm. Dark coffee trickled down the wall, pooling on the floor.

Silence trickled through the room as quietly as the coffee dripping to the floor.

Dean released a sharp breath, frustration thrumming through his veins. He stood and began to clean the mess.

As it was, he knew how to do this; clean, scrub, listen, repeat...

Chapter One: The Trenchcoat Angel

Please...

Are you there?

My mom, please...

Help me...

Please...

A pair of dark blue eyes snapped open.

The prayers of the humans could be overwhelming at times. There were so many, all of them piling up on top of each other, becoming this odd, layered voice.

Shaking his head, the angel Castiel built a wall between his mind and the prayers, until silence fell once more.

Studying his surroundings, Castiel frowned. He stood alone, by the edge of a vast lake- in the state of Michigan, if he wasn't mistaken. The air was cool, but he did not notice. His vessel, a man once known as Jimmy Novak, had dressed in a suit topped with a trenchcoat.

Castiel had possessed his body before the soul had been lost in a fight between the angel and a demon. Castiel had lead the soul to heaven, where it found peace, and had kept possession of the body. He oddly preferred keeping it over finding another.

Castiel rubbed his chest, remembering the fight. It had been against a low ranking crossroads demon, who had been lingering at the local watering hole and making deals that ended with the damned souls being dragged into hell by hellhounds. This demon, however, had forgotten to be subtle and Castiel was sent down to "take care of it".

More and more now, the angels were descending from heaven to deal with the rise in the demon population. Even though there was less angels than there were demons, the angels were far more superior in their fighting skills and powers. Most of the demons were low ranking, with the occasional crossroads demon. These were easy to deal with. The worry rested with the question of how much longer it would be before a strong demon escaped from hell.

Although the seals were safe, and Lucifer himself would not rise, the human population would soon decline with the amount of demons finding their way into the world. Demons took pleasure in killing humans without a thought, like many other supernatural creatures. Having the angels descend was a short term solution.

Castiel turned his gaze upwards. He did not question his orders. He knew that God wanted the angels to love humans like he did (or was it had?), so the angels did what they believed was their duty. There was no room for questions or doubt- these were pathways that would make an angel fall, much like Lucifer did.

"It's peaceful here," a thoughtful voice said from behind Castiel.

An angel blade suddenly appeared in his hand, and when he turned, it was met by another. He recognized the angel smirking at him, and relaxed. He dropped his hand to his side. "Anna."

Anna returned her blade to the sheath she had strapped to her thigh. Her large, green eyes turned towards the scenery, as if nothing had happened. "I often find myself admiring our father's work. This-," she gestured widely, "is a reminder that not everything he created was evil or bad."

Castiel studied the red haired angel. "Why are you here?"

When she sighed, Castiel could almost see her wings twitching with annoyance. "Uriel has found something."

Castiel knew there was some tension between Anna and Uriel, since the former was the commanding officer- to use a human phrase- of the latter and Castiel, and Uriel wanted the roles to be reversed. Although the other angel would deny his jealousy and displeasure, sometimes those emotions interfered with their missions. Castiel understood why she looked equally displeased when they were dispatched on missions.

"Where?" he asked.

"Lawrence, Kansas."
