Castiel was barely listening to Damien. He knew what his partner was saying was important but the power was already swimming about in his head, intoxicating him far more significantly that any drug he had tried. He was still watching the girl like she was a unicorn grazing on his front lawn, his eyes glistening in the sun.
Castiel's mind latched onto one phrase, That which is Holy. He smiled. "You have nothing to fear from me," he said cheerfully. Pleasure. Another keyword. "And my touch has also brought much pleasure. As for the rest... I don't want to use this power for inflicting pain." And Castiel realised that he only had half the equation. He had the power but not the purpose. It was raw, directionless. Unfocused. It burned though his body, aching for release. All the control had to come from him. His limits were his to set.
Castiel looked Damien up and down appraisingly. "Sooo, what do you do for fun that may be suitable for someone of my former allegience?"
