Plot hole: 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?
