Origin
Steve got her first thrill of killing, when her father popped a brain vein in a play fight with her. Her ex-husband had a bad reaction to pain killers he needed to endure their sex plays. In the military intelligence, she saw the detainees being manhandled by the guards. Leaving the military, she got into personal security.
She killed her client and fed him to the Crossed as a distraction. She crossed America alone on her bike, until she met Gregory Costello. After a short bout of sex with Gregory, she accidently became pregnant. She gave birth to a son, after she had survived her teammates Gregory, Leon and the twin sisters Ashley and Ashlynne had all been infected by the Crossed virus.
