Teen Wolf, Season 3

Jennifer:
For years, the Nemeton's power was virtually gone, like the dying ember of a burned out fire. But a few months earlier, something happened that caused that ember to glow a little brighter. Something that gave it a spark of power again-- the sacrifice of a virgin. You didn't know what you were doing back then, but killing Paige in the root cellar, sacrificing her there, gave power to the Nemeton. You gave it power again. You gave me power. Just enough to hold on to life a little longer. Long enough to be found.
