I never trusted you, from the moment I saw you.
~ Stephen Coyne's last words

Steve grew up in rural Birkland, moving to the city at the age of sixteen. While being arrested for battery, Steve badly beat an EBPD officer and was sentenced to ten years, of which he served five. It was in prison that he started working as muscle for fellow inmate Derek Pappalardo, a relationship that continues on the outside.
