Little is known about Rezza, but the rumours are that he grew up on the West Coast, somewhere around California. He was moving a lot with his family as a child/teenager because of the troubled areas they stayed in. As a teenager, he started getting into trouble with the law a lot. Another person of unknown origins and name was always around with him and they were like brothers. Getting into trouble together. That was until one faithful night where something went wrong and Rezza ended up in severely injured, his friend disappeared and the rest of the people he used to hang around with disappeared too or have been killed for what they got into.
Rezza then moved to the other side of the Atlantic ocean alone in his late teens, and as soon as he arrived on the shores of the UK, the outbreak happened. Nobody knows why he left the US and headed for Europe, but rumours are he was following messages his friend left. While being in Europe, he met people who he now calls Brothers.
