Kevin Johnson is a former victim of Candice Long.
At some point after his birth, Kevin became a foster child and got sent to juvie.
A few weeks before Batwoman interrogated a Snakebite dealer, Kevin was abducted by the Candy Lady. After breaking Kevin by making him believe nobody wanted him, she sold him to the False Face Society. In order to prove himself to the gang, Rudy wanted Kevin to kil Jacob Kane, but Kevin decided not to do this as Batwoman arrived on the scene and made Kevin believe that he was meant for so much more than being in a gang and killing people.
