Can someone explain? I get the whole thing with the black dude and what his test was, it's the cop that was part of it that I don't understand aswel as the cop that got locked in the room at the end. The cop that saw his partner get glass in her face had her blood on his t-shirt so it's certain that the black dude was doing his test while this cop was trying to find him, however at the end the cop walks into the final scene of Saw III. How is this possible? Jigsaw is lying on the table after just being killed (end of Saw III), however at the start of this film he was in the autopsy.
Someone please explain to me.
EDIT: Nevermind. Got confused by the autopsy being at the start and that completely put me off track. Tis all good now
