I speak for the dead.
— Logan[src]

Logan Nelson is a fictional character from the Saw franchise. He is introduced as a main protagonist in Jigsaw, before later being revealed as the secondary antagonist of the film.

He is portrayed by Matt Passmore.


Early Life

Prior to his test, Logan Nelson served in the military as a medic and a tour in Iraq during the Iraq war, during which he was captured (but not before killing 3 rebels), brutally interrogated, and traumatized, leading to his discharge. He later returned to medical school to pursue a career as a medical examiner.

First Test

Logan was the fifth participant in the series of traps placed in the Tuck's Pig Farm due to his negligence as a medical resident while labelling John Kramer's x-ray and delaying his diagnosis of an inoperable brain tumor. During the initial Bucket Room trap, Logan failed to wake up until Ryan, Anna, Mitch and Carly, the four other victims, had freed themselves and begun to move on to the second test, not allowing him to hear Anna's realization that to be released from the headpiece they would need to cut themselves.


Before he could be pulled further into the blades, John entered the room and released Logan from the bucket headpiece, deciding that Logan should not have to die because of his own unintentional miscalculation. John proceeded to take him back to his lab and mend his wounds. Feeling gratitude towards John for sparing him, Logan began to work alongside him as his first disciple, even helping John to build the original Reverse Beartrap. It was during this time that John began teaching Logan of his philosophies, with the words "we'll speak for the dead" having the most impact on Logan.

Jigsaw's Successor

Halloran talks to Logan

In the time after the death of John Kramer, Logan was active on a Jigsaw fansite on the Dark Web and sold some of his and John's blueprints for torture devices, including the Cycle Trap, which was completely unknown to the public. Years later, in order to get revenge on Detective Brad Halloran, a corrupt police detective who freed a criminal that murdered Logan's wife, he built a replica of the game in which John had tried to test him 10 years earlier. Logan's goal was to kill some of the criminals Halloran had helped walk free, thus framing him for their murders. The first victim Malcolm Neale, who died from getting sliced up by the buzz saws and was hung above a bridge. He was visited by detectives where he and Eleanor Bonneville examined the body. After being at the morgue and needing more evidence to find the criminals behind it.

Logan observes the reverse beartrap.

Halloran became suspicious of Logan and Eleanor. In an attempt to throw him off he killed Edgar and buried him in John's coffin, continuing the ruse that John may be alive. After a second body appears, Logan decides to visit Eleanor at a bar where she takes him to her replica warehouse unaware that Keith was following them. After the police raid the factory and find the third body Keith arrests Logan where he places the blame on Halloran and is let free, after manipulating evidence. After trying to phone Eleanor he finds her next to him where she tells him that she found where the original game played. They are followed by Halloran, and while Logan appeared to be knocked unconscious, he later subdued Halloran.

Laser Collars

Logan and Halloran wake up in a room with collars strapped to their necks. They are then told via a speaker with John Kramer's voice that they must confess why they deserve to die, or they will be killed via multiple laser cutters to the skull. Halloran signals his intention to confess first, only to press Logan's button, forcing him to speak instead. Logan confesses to mislabeling John's X-rays years ago, only to appear to be killed anyway. Halloran then confesses to being a dirty cop and letting criminals walk free, which make his lasers stop. He then notices that, unlike his own, Logan's lasers did not cause burn marks on the ceiling. He also notices that Logan's collar contained blood capsules, which had burst to make it look like Logan had been killed.

Logan, alive and unharmed, stands up. He then reveals that, ten years ago, after he was injured by the buzz saw trap, he was saved by John. Logan also talks of his suffering in the war, and how Jigsaw gave him renewed purpose, ultimately leading to him deciding to continue the legacy and became an apprentice to Jigsaw's ways. Logan informs Halloran that what he wanted to hear was a a confession to helping Edgar walk free for killing Logan's wife. Logan then leaves, claiming that Eleanor will be his alibi, allowing him to remain free. He then activates Halloran's lasers, gruesomely slicing his head into pieces. He seals Halloran's tomb, with the parting words "I speak for the dead". He then closes the door, sealing Halloran's body inside, and walking away, free to continue his work. (Jigsaw)


Before he became John Kramer's disciple, Logan was a broken man due to his experiences in war, even having PTSD-like flashbacks or nightmares. This trauma led him to become careless with his work, shown by the fact he mislabeled John's x-ray results. It also led him to have trouble focusing, and left him without a purpose. However, he was also shown to have a strong sense of justice, as when John told him they can never come from anger or vengeance, he simply replied that there would be no justice for the victims of those that they would test. It was his work with John that allowed Logan to heal to a degree from his trauma, and to regain a purpose in life.

Logan has shown that he is quite vengeful as well, due to the fact he tested both Edgar and Halloran due to the roles they had in his wife's death, even though this goes against John's philosophy that the tests can never be personal. His sense of justice was clearly seen when he replicated John's first game, as all of his test subjects were criminals that Halloran had allowed to go free. Logan has also shown himself to be highly intelligent, able to replicate John's first game quite well, as well as maintain the ruse that John himself may be alive, as well as framing Halloran as the new Jigsaw, all the while giving himself an alibi. Logan's intelligence is also shown in his ability to create high-tech traps for his games, with the Laser Collars being the best example of this.

His military training has also given him skills with firearms and tactics, as he was able to accurately shoot Edgar with a sniper rifle in such a way that he was critically wounded but not killed, with his tactical training allowing him to quite expertly frame Halloran.

Despite all of this, he has a healthy relationship with his daughter, playing catch with her and allowing her to sleep in his bed when she has a nightmare.

Despite this, Logan appears to be slightly hypocritical. As his (presumable) reasons for wishing to succeed John are to exact vigilante and personal justice on criminals and corrupt cops, rather than to test people's will to live, which goes against everything John believed in. He is, to an extent, even willing to break the rules John set for his survival games. This is shown when Halloran reminds him that Jigsaw gave people chances to win his games, Logan cruelly tells him that he does have a choice: scream, or don't. However, Halloran did not confess to pressing Logan's button and forcing him to go first, nor did he explicitly confess to releasing Edgar Munsen after he killed Logan's wife, and the test was to confess his sins, so it is possible that Logan saw this as Halloran failing.


  • Due to not regaining consciousness in time to know what was going on, Logan didn't participate in his test.
    • As such, he is the only survivor of the tests taken place in the Pig Farm.
  • He was one of two John Kramer/Jigsaw disciples alongside Lawrence Gordon who survived and continued Jigsaw's legacy.
    • Like Dr. Gordon, he has medical training, and like Hoffman, he used Jigsaw's M.O. to gain revenge against someone responsible for the murder of a family member who did not get punished, although for Hoffman it was his sister, while for Logan it was his wife.
  • He is the oldest known survivor of John's game.
  • Logan was born on August 18th, 1973.
  • He is the only one of Jigsaw's disciples who didn't use the familiar quote "Game Over" at the end of a game. Instead he said "I speak for the dead".
  • Like Hoffman, Logan constructed a Jigsaw like scenario for the purposes of revenge, however he did this after being recruited by John.
    • This was a betrayal of Jigsaw's philosophy that tests could not be personal. Rather ironically, this undermined his intention of seeing if he was a worthy successor to John, ultimately proving he would be unworthy in John's name.
  • It is very likely that Logan is the one who leaked the story of the Jigsaw game that was never found, as well as the blueprints for Jigsaw's traps to the Internet that Eleanor later used to create her replicas.
  • Logan’s M.O. is slightly different than John’s. John would leave his victims where they died (except for Cecil Adams, whom he had to dispose of due to where he died) while Logan displayed his victims’ bodies in a very theatrical fashion as a way to antagonize the police, (the only exception being Detective Brad Halloran).
  • Although being revealed as the Jigsaw killer near the end of the film he is not necessarily the main antagonist, mostly because it was Halloran's actions who led Logan to continue John's work after the death of his wife ultimately making Halloran the film's main antagonist as his actions had the most impact on the film.
  • Keith stated that Logan killed 3 Taliban in Fallujah, however this is impossible as the Taliban are based in Afghanistan, not Iraq. This may have been a mistake by the filmmakers.
