Continuity mistake: Detectives Cosgrove and Shaw head to the hospital to interview a doctor which they do in a hallway. At one point the door behind the doctor is a single door then it changes to two doors and then finally when the detectives leave there is no door at all.
Suggested correction: Dr. Mercer and the detectives stand at a T-intersection of 2 halls (Cosgrove and Shaw at the top arm of the T). In 2 shots facing Mercer head-on, a single door is at the end of the hall directly behind her. In a shot facing Mercer's right side there are double-doors beside her, to her left. The last shot of Mercer is head-on with the single door at the end of the hall. When the detectives leave in the shot from a new angle, we cannot see the hallway (at the right) where Mercer stood, only the opening to the hall (00:18:25).
