If you recall during Andy's stay at the mental hospital, there was a scene where Chuckie was chasing Andy. He chases him into a room where the doctor finds Andy and is trying to sedate him. Chuckie stabs the doctor and then attaches an shock therapy helmet to the doctors head. As Chuckie electricudes him, the doctor starts to bleed from his eyes and mouth. When the film cuts away and then back to him. The doctors eyes have absolutely no blood in them.
