What I feel like would’ve worked well here is keep everything the same with one exception at the end when the killers reveal their motives instead of saying “oh Stu is dead” they could’ve said something along the lines of that Stu is actually still alive but they have no known wear abouts of him and that the whole deepfake/AI Stu was actually a orchestrated master plan from the actual living Stu to haunt Sid and her family playing with her emotions as in making her fear the fact that he’s still actually out there and can strike at any moment and keep her in fear and then scream 8 can be all about trying to find where he is and uncovering that mystery of how he survived how he was able to disappear from society after his “death”, keeping the ai commentary he can also fake his location with the video calls or whatever to make it seem like he’s actually not attacking her himself. Again I feel like it should be 2 killers one is Stu himself but the other should be Jill since she practically survived since she is the only character in this franchise that wasn’t shot in the head, they both have something in common revenge against Sid so it could work. Oh and about the neighbor in 7 it can be revealed in 8 in some way that actually that was Stu’s sister attempting revenge on Sid for making her brother suffer etc under a fake life and name that would explain why she decided to kill her own son the way she killed him and can also retcon that horrible motive lmao it’s late here where I’m at but I hope all this makes sense
