Sacrifice
The body beneath him finally stopped moving, the faint hints of life now gone. No air passed through his nose or lips.

He turned away, leaving the young man's limp form lying on the ground, eyes rolled up into his head. High above, Buffy struggled with her decision. He couldn't know her plans. He had no idea what her sacrifice would be.
