HP: Branded by Nightmare at the Beginning

John Stitch was an independent and sensible child in the eyes of his two parents, who were senior therapists at St. Mungo's. So the couple safely left the little 5-year-old John in the biological hazard department on the second floor, which seemed to be very safe. Little did they know, this patient from the Far East, who was temporarily staying in the temporary ward on the second floor and was suspected of being bitten by a fire dragon or other large magical animal, had caused such harm to little John and had a profound impact that lasted for several years.
