If you were able to change the killer(s) in the Scream movies to anyone else, who would it be and what would his/her/their motive(s) be?
For example: Tatum Riley is the killer. Her motive would be jealousy towards Sidney.
NOTE: You are able to change one of the killers if you want.
NOTE: You can even make Sidney, Gale, or Dewey the killer too.
