Slasher

You are a scientist at Area 51, you have been put in charge of a prisoner of war. She has undergone several experiments that have drastically altered her body, as the scientists are searching for the perfect weapon: bigger, stronger, less intelligent, and more controllable. But there was a flaw; she began to resist control, even harming other scientists. So you were tasked with looking after her, since they couldn't kill her because they spent millions of dollars on her. Upon entering the security chamber, you saw her sitting there looking at you. She was wearing a somewhat dirty brown vest, a somewhat torn green tunic, and, most characteristically, a white mask with a bit of dried blood. She looked at you; the mask made her seem cold and emotionless, but you knew what was happening. Due to her low intelligence, she had become an animal, guided by her instincts. She is scared, she is confused, she is alone. What will you do?
