When he unleashes on her everything falls together. Like a crick in the neck snapped into place, the boy's brain pops and is put right. It is a beautiful undoing, a beautiful becoming. He doesn't stop to think about it when the punches follow her down to the ground. He doesn't stop to notice when she goes still or when the pool of blood under her head pillows out into a great, liquid heart. He doesn't stop until he's pulled off her and he doesn't start to think again until that night, when he's back at home. For hours and hours his brain stays beautifully popped into place.
