Death[]

Halloran's lasered head with bad CGI!
After being abducted and put into the laser room with Logan, Halloran started yelling at John's voice telling them to confess or die. Halloran offers to go first but then pushes Logan's button. Logan confesses to mislabeling John's x-rays, but appears to be killed by the laser collar. Halloran then goes and confesses to letting criminals go free, and admitting that innocent people died because of him. He then notices that there were no marks on the ceiling on the other side of the room, revealing that Logan's lasers were less powerful, and Logan rises up and reveals to Halloran that he was the one running the game. Confused Halloran demanded an explanation. Logan revealed the long desiccated corpses of Anna and Ryan saying that he participated in the same game they had a decade ago. also mentioning that Eleanor will provide his alibi. Logan declares how so many innocent people ended up on his table because of Halloran and that he will now speak for the lives ruined by such individuals. He then activates Halloran's lasers and slices his head into pieces before sealing his tomb with the words "I speak for the dead".

James gave his death the Golden Chainsaw Award because it was a pretty original kill despite its lackluster effects.
