Dean was lucky to get the shot off before he went flying backward, through the air landing upon his back on a headstone, bouncing off it and sliding down it with an "Umph."
He was stunned for a moment, shaking his head, Dean saw another figure flying at him to land next to him. He turned his head, only glancing at the young man before getting up. "Get the hell out of here!" He shouted at him as he dropped his gun and pulled out his wooden stake and machet.
Dean saw the fangs so he knew what it was. Vampire. Stake it then kill it. An dhis stake was dipped in dead man's blood. He didn't hesitate as he charged at the vampire.
