Castiel had just lost his grace, he was lost and alone with no one to turn to. One night, as he was making his way back to where he was staying when he saw a girl. She was stood still on the edge of a bridge, one foot over the edge. He needed to get to her, her. He watched as he ran. He watched her long brown hair, he felt her pain. He didn't know why. He just had to save her.
