Jessica Sanders is the name of Nikki Sanders' adopted sister, who was killed in 1987 by their adoptive father Hal. Later Nikki's doppleganger takes on the persona of Jessica when using her super strength. When Jessica is revealed, Nikki becomes somewhat trapped in her mirror. By the end of the first chapter, Nikki seems to have her control over Jessica and seeks help to get rid of her second personality. It should be known that Jessica is just a personality created from the reaction of Nikki seeing her sister abused, and not at all the true Jessica Sanders possessing her body.
