Deborah Harper es una universitaria de 20 años. Es la hermana de Helena, pero su forma de vivir la vida es totalmente distinta: Deborah es despreocupada y amante de las fiestas. Esta diferencia ha sido motivo de muchas discusiones, pero en el fondo las dos están muy unidas.
Sin embargo, sus vidas se van al traste cuando Derek Simmons secuestra a Deborah y la usa como conejillo de indias en los experimentos del virus C de la Familia. Cuando Helena consigue encontrar a Deborah, su hermana ya no es la misma: la han convertido en una criatura horripilante que ha perdido cualquier semejanza a un ser humano y que únicamente conserva ciertos rasgos faciales que sugieren que antes fue una mujer bella.
Deborah Harper is a 20-year-old college student, and Helena's sister. Unlike her sister, Deborah is a carefree party girl. Their different approaches to life are a cause of friction between them, but those issues aside, the two are actually very close.
The two sisters' lives are thrown into chaos when Derek Simmons kidnaps Deborah and uses her for The Family's C-Virus experiments. When Helena is reunited with her sister, it's not the happy reunion she had hoped for. Deborah had been turned into a hideous creature with no semblance of the humanity she once had other than the gentle facial features that hint at her former beauty.
Below is a memo written by a member of The Family detailing their actions after taking Deborah hostage.
We've been ordered to kill Deborah as soon as Helena leaves. They'll both be dead eventually anyway, so doing so would speed up the process. But it would be such a waste to kill her. I can't help but think about her soft skin and shapely body. She's just my type.
She's a little beaten up, but she'd make a wonderful subject for our experiments. I think I'll keep her around and see how she takes to the C-Virus.
