Corrected entry: When Jigsaw gets up off of the ground, when he says to Adam "the key to that chain is in the bathtub", if you look at his inner right arm, there is a black wire on it. The wire is attached to his arm by masking tape.

Correction: How is it a mistake? Jigsaw might have been using the wire and had to keep it in place.
