She is a hellish sight as she breaks, but he is a worse picture to look at. He is hollow and void and terrible as he kills her, and he can't manage it fast enough. His own blood is on him, and he limps, and for a moment he thinks she'll win. He nearly lets her. He doesn't know why he can't. Doesn't understand why he will not let himself die, and let her live. He makes a mistake. In that moment he wants to die more than he wants her to live.
Oh, God, that awful smile. It's gruesome.
