Once he was done with her, Dorian duplicated the blood on her body so it wouldn't look like he had drained her, left her on the floor, and searched for the baby's room. Screams had woken him up, but he was smiling. He wanted to play. Dorian looked at him for a moment, contemplating the mystery of life and death, and reflecting on the fact that the spark that animated that little body and made him smile would soon be extinguished forever. He cut him in half and repeated what he had done to his sister. He also sucked his blood into a vial, duplicated it, and spread it over the crib so that the Muggle police - and especially the Aurors - wouldn't understand that a bloodletting had taken place.
