Abby was out killing Infected, like normal. She was just trying to get it done as she blasted them with her shotgun. When that was finally over she had hear someone or something? Abby didn't know what it was but she was ready to shoot whatever it was if it was gonna harm her. She got closer, only for the sound to get louder. Abby quickly turned the corner pointing her gun at whatever it was. But it was just a person..?
