At the beginning of the movie, Jigsaw's body is on an autopsy table where they find the tape in his stomach. But at the end, Jigsaw's body is back in the hospital bed in the room from SAW III. Did I miss something? Granted it was midnight when I started watching it, but I know I did not nod off.
The only thing I could think of, is that it started at the end and went back to the beginning that led up to that point. I don't know.
