So I was think that the same scene in the movie but Gale dies, Y/n is force hold Sidney still and is also force to be stab but then billy or Stu kills Sid dad with the gun but Y/n is forced to kill Sidney and kills her crying saying he’s sorry and Billy and Stu are proud of him but Billy and Stu drugged Y/n and locked in a basement in a secret place that nobody but Billy and Stu know but takes care of him (Randy is also dead)
