Stu Macher hadn't anticipated his plan to go wrong. Him and Billy had had it all planned out kill everyone and then stab each other barely surviving and framing Mr. Prescott but Billy had hit him pretty badly on his arm and stomach and Sidney was on the run. Suddenly another survived came out of the side room when Billy left. It was Stu's girlfriend he thought Billy had killed her but though she was covered in blood she was still alive.
