Which Killer Was Which?
I remember watching this as a teenager and trying to figure out which killer for each scene. Watching it again, it's still fun to figure out. So what's the general consensus? My theories:
Casey and Steve - (Phone) Billy, (Killer) - Stu was with Tatum and the killer on the phone knew details where he had to be there ("Turn on the porch light. Again.")
Attack at Sidney's - (Phone) Stu? He can't see her and since there's one killer in the closet and she would hear him speaking from inside the house, it had to be a tag team effort; (Killer) - Billy
Phonecall to Sidney at Tatum's - Stu. In spite of Sidney's suspicion about Billy's one phonecall, it would've been stupid to call her on a line that is easily traceable.
Grocery Store glimpse - Stu? Only because he tells them to bring food.
Woods outside of Tatum's house - No idea.
Principal Himbry - Stu? Sidney and Tatum are leaving the school - Stu walks back the way he came.
Tatum - Billy, I used to think this was Stu, but Billy gets to the house right after and apparently Skeet confirmed that it was Billy in that scene.
Kenny, Dewey, and the attack on Sidney - Obviously Stu, since Billy is upstairs the whole time.
