So this is kind of an AU I suppose. Set in series 1. I own no original characters. Blah, blah, blah.
Dean Winchester took a seat at one of the barstools in the cheap pub down the road from where he and Sam where staying. A teenaged girl with long lilac hair that was tied back in a plait and who was wearing a white silk button-up shirt, black jeans and biker boots sat down next to a man in a trench coat and chewed her lip. Three scary looking man walked in and she tugged on the man's sleeve. He looked around, nodded to her and lead her out. The men followed, and Dean saw one of the flash a gun. Not one to stand by while others got hurt, Dean got up and followed them. The men backed the girl and the trench coat guy into an alley. The trench coat's hand glowed and he tapped one guy on the forehead and he dropped to the ground. One guy hit the girl in the jaw with the butt of his gun and she growled and slammed a punch into his nose. "Hey!" Dean yelled, stepping out of the shadows. The girl's face brightened and she took a step towards Dean, but one of the men grabbed the back of her collar and threw her into the wall. The plaster cracked where she hit it but she slumped down and didn't move. The two men stepped up behind trench coat and slit his throat. Dean was too scared to move, but was able to see the men drain a blue substance into a bottle and then man to stagger away. The two men disappeared with a crack and the smell of ozone. Trench coat saw the girl lying on the ground and dropped down to her side. Dean regained himself and picked up the girl. "Hey you, come with me. I can fix her." he said. Trench coat walked beside him and Dean snuck glances at his piercing blue eyes.
