I will explain why I made Kirby Judy's killer in the epilogue.She is not a Ghostface.
Det Ben Dennison-Cecily killed him at home,she came up from behind him when he was watching the 1980 version of Friday the 13th and slit his throat as he lay gurgling on the ground she went over to where the TV wason the cart and pushed it so it would land on his head.
Bobbi Chin-Cecily killed her when she saw a car pulled over when it's trunk up,she looked in the driver side saw no one inside then she went around to the passenger side to see if they went down into the woods when suddenly Cecily came running up to her and stabbed her in the forehead she then dragged the body in to the woods and continued to stab her. It turned out that the Academy had accepted Bobbi instead of her.
Lt Rob Miller-She killed him by attacking him when he got into his car she stabbed him in the chest and worked her way up to his face she rammed her knife into his mouth then she took his badge which wasn his belt and shoved it into his mouth,she then took his gun.
Mary Thomas-Cecily killed her so she could get a police officer to show up at the scene which was at a dark parking lot late at night.
Officer J.T. Barnes- He was who responded to the call she shot him 6 times 5 in the chest once in the head with Rob's gun.
Officer Nick Cain- Cecily killed him because he was boyfriend and she didn't think he fought hard enough for her to get into the academy.
Cecily Randolph-Sam Macher shot her to death when she tried to attack Carmen in the police parking lot.
The reason I made Kirby Judy's killer was because I thought it would be more shocking to make it someone who the audience knew and cared about and they would want to see what happens next.
Kirby's MO-She is very upset that everyone has forgiven Fifi for killing their friends just because she has a split personalty. It turned out hat she was only pretending to be Fifi's friend after she found out that Fifi was a serial killer.No one forgave Jill for what she did ,she thinks people shouldn't forgive Fifi either and she wants to show that Fifi can't be trusted. She will do other things that will make Fifi look even guilter. Jessica will start to realize slowly that while Fifi is a very dangerous young woman she isn't evil and she will help Sam again in his investigation to find Judy's real killer.
