Other mistake: Jill's shoulder seems to be perfectly fine when fighting with Sydney, even though she stabbed her shoulder earlier. (01:38:00 - 01:40:00)
Suggested correction: Anger and fear can be more than enough to gather enough strength to fight your way out of a difficult situation regardless of how much of a critical condition you are in.
Factual error: Spoiler: I saw this with two nurses who pointed this out, so I know this is correct. The final sequence takes place in a hospital room in ICU. Jill pulled out IVs and electrodes that were attached to her, then proceeded to Sydney's room. She pulled the call button, then tossed Sydney around the room. Glass shatters. She knocked Dewey out with a bedpan, fired a couple of shots from a gun, and yelled at Sydney, Gail, and the deputy. Sydney even fired the gun at one point. All of this goes on for quite some time, making a hell of a racket in ICU. The problem? The medical staff and security. Any nurse at the nurses' station would have been alerted automatically when Jill pulled the electrodes off herself, and also when the call button was pulled from the wall in Sydney's room. Within seconds there should have been someone come to the rooms to see why they were alerted, but the only time you see a nurse was when Jill hid just inside a door while making her way to Sydney's room. One walked past on her way somewhere as if nothing unusual was occurring. The subsequent fight occurs and you still don't see any hospital staff. So where were they?
Suggested correction: The answer to "Where were they", is; "at the mandatory meeting for all non-emergency personnel in the basement conference room." No, I am not joking, it's a message that you can faintly hear in the background (and the subtitles make sure to include it) from the hospital IP speakers. It's ludicrous and I am not saying that it corrects the entry, especially since it does not cover the fact that there should be automatic alerts and some personnel is on duty at their stations as precisely described, but just saying that the script somehow wanted to set up / justify it.
I'm changing the type to "Factual Error" to cover this. It's not a plot hole, it's just a really, really, really, really, really, REALLY badly run hospital as far as security is concerned. And if the hospital seen in the following 'Scream (2022) ' is the same one, it's just further evidence that it's simply a really crummy hospital.
Audio problem: When Jill reveals herself as the second killer, we hear Sidney say "Jill". But her mouth doesn't move.
Suggested correction: You can say "Jill" without moving your mouth.
