Kate's running through the mansion when the killer jumps out at her. They both fall down the stairs. Kate gets up, then the killer sits up. Adam shoots the killer from the top on the staircase and runs down to Kate. Adam hugs Kate and crawls over to the killer. He removes the mask to reveal Dorothy. Kate cries and Adam holds her in his arms. But then Adam's nose starts bleeding(The killer gets a bloody nose everytime he kills someone.) Adam is still cradling Kate then the screen cuts to black and we hear Kate start screaming. Dorothy was never the killer, she was framed by Adam who was the killer the whole time.
