With 1:28 minutes left, Bobby starts pulling himself to the ceiling, using the chains that are attached to the hooks in his pectoral muscles, the trap he claimed to have survived. At 40 minutes, he reaches the ceiling and attempts to put together the cord that will deactivate Joyce's trap. At 28 seconds, he is just about to bring together the two ends of the cord, when the hooks rip through his pecs and he falls to the ground. The clock keeps ticking 9...8..7... until ...1, when a brazen bull capsule closes around Joyce, essentially boiling her alive. Bobby is electrocuted when he attempts to break through the wires surrounding Joyce's platform.
Meanwhile, Hoffman makes his way through police headquarters, killing everyone in his path, until he finds the cell where Jill is. She attempts to get away by stabbing him in the neck with a pencil and running. Hoffman finds Jill hiding in an evidence room and drags her out, then straps her in a chair and places a Reverse Bear collar (one of the traps on the shelf in the evidence room) around her head. Her life flashes before her eyes until the clock runs out and the collar rips open her mouth. 'Game over,' says Hoffman smugly.
Hoffman heads back to his warehouse hideout, packing somethings and setting the place on fire to destroy the remaining evidence. While heading to his car, Hoffman is attacked by three people wearing pig masks. The leader pulls off his mask: It's Dr. Gordon. It's revealed that, after Gordon escaped from the bathroom and used a steam pipe to cauterize his leg wound, he was rescued by Jigsaw and nursed back to health. Gordon became Jigsaw's 'greatest asset', providing the surgical skills needed to perform some of the more delicate procedures required for some traps (sewing keys into people, sewing eyes/mouths shut, etc). Gordon is also the one who recommended Dr Lynn Denlon for Jigsaw's operation. He also wrote the note to Hoffman found that said, 'I know who you are.' It is revealed that the envelope Jill slipped under someone's office door was for Dr. Gordon, with instructions on what he was to do should anything every happen to Jill (as it has become clear that Jigsaw never truly trusted Hoffman). Jigsaw also reveals to Gordon the location of the room he was locked in.
In the final scene, Hoffman awakens in that room, and finds that, similar to Dr. Gordon's original trap, he has been chained to the wall. Unlike Gordon, however, he will not be given the chance to escape. Hoffman was given a second chance by Jigsaw (as seen in Saw V), and chose to continue a life of brutality. Hoffman reaches for the hacksaw and Gordon smiles and says "I don't think so." before picking it up and throwing it out of the room. As he leaves, Gordon turns off the light, tells Hoffman "Game over" and closes the door, leaving Hoffman to starve to death.
