Welp I thought about that once or twice. Stu is disfigured from the events of Scream 1 and you would imagine because of him doing the Murders with Billy he needed to hide from everyone. I've seen Sith Lords bide their time and getting someone like Anakin Skywalker to join the Dark side going back to him being a little kid. It could be the perfect time to come back if they wanted to bring him back.
I know that they toyed with the idea of bringing him back for Scream 3. Which, no matter how ridiculous, probably would have been a better ending than the one that we got.
But I’m just not sure it’s the right direction to go, just because a lot of the fans want it to happen.
I did rewatch the film on Sunday and I’m still mad about that hospital scene with Dewey. It was like the ending to Scream 4, where the hospital was completely deserted. That wouldn’t happen in basically any country in the world.
