Marie Thomas lived in Cardiff in the 21st century. She had HIV before being dosed with Reset from the Pharm. Billy Davis was sent to kill her before any weird symptoms showed up in public. However he did not succed because her dog bit him then she kicked him in the nuts. But she still had Reset inside her. She later died in hospital but the Mayfly inside her came out and attempted to enter Martha Jones and Owen Harper but died before they could do so. (TW: Reset)
