Deborah Harper

Deborah Harper is Helena's younger sister in Resident Evil 6.

History
Deborah was born on October 10th, 1992 and was four years younger than her sister, Helena. With their parents having died some time before she turned 20, she maintained a playful and spirited personality as she became a university student. She was very close to her older sister as a result of their parents' death. At one point, Deborah got into an abusive relationship with a man, who beat her to the point of hospitalization. Helena saved her from the abusive relationship by shooting Deborah's boyfriend, inflicting serious injuries. Unfortunately, it was this incident which led to Derek C. Simmons considering using Helena as a scapegoat for his plans. Deborah and her sister were abducted by Simmons three days before the events of Leon's story and were shown to be held hostage by him in the laboratory beneath Tall Oaks Church. Helena tried her best to keep her terrified sister calm. Under Simmons' command, men come to take Deborah away, leaving Helena to futilely beg and plead for them to let her go. Helena offered herself to Simmons in exchange for her sister. Her pleas did nothing as Deborah was dragged away to a then-unknown fate.

Simmons used Deborah as a bargaining tool to get her sister to help him carry out the bioterrorism attacks on Tall Oaks and assassinate the President. Despite Helena obeying Simmons in causing the death of the President, Deborah was ordered to be terminated. Instead, members of 'The Family' decided to intervene. Rather than kill her and dispose of the body, 'The Family' wanted to see what the C-Virus would do to her youthful healthy body. She was injected with the virus soon after and kept under observation. Despite high hopes and excitement regarding her mutation, Deborah's body showed no visible signs or effects of transforming. After an hour of waiting, 'The Family' had to abandon their plans and evacuate Tall Oaks before it was eradicated to quarantine the area. Disappointed, they left Deborah in the lower levels where Leon and Helena happened to find her.
