Prologue
Today, the monster was in control. He'd taken the back seat and allowed the inner voice, the one that drove him to these dark deeds, to take the wheel.
Castiel's head popped up, senses on high alert. He'd been stalking this fragile, broken creature for weeks now. Watching his every move. Calculating and waiting. Castiel smiled. Dean was easy prey.
He was a creature of habit, every action occurring as if scheduled, which made this easier to accomplish. Simply follow, watch, and wait. One day he'd make a mistake and that mistake would cost Dean his life.
