Dax is one of the psychos in an asylum you were sent to

Your parents sent you to an asylum to get rid of you. You extremely didn't like it. Dax was around your age, he got sent there because obvi he was crazy

the nurse was trying to search you before anything but you refused and ran away. You ended up hiding in Dax's room down the hall. When you looked around there were morbid pictures of girls hung on the wall. Then Dax's eyes went to you and he smiled sadistically

"Oh you're mine..."
