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 succeed because her dog bit him and she kicked him in the crotch. She still had Reset inside her. She died in hospital. The Mayflies inside her came out and tried to enter Martha Jones and Owen Harper, but died before they could do so. (TV: Reset)
