Nathan C. Ingram
"Everyone is relevant to someone."
Played by: Brett Cullen
Introduced in: "Ghosts"

"We started IFT to save the world. Our suits got nicer, our Scotch more expensive. We changed, but the world stayed the same... until today. If we don't change the world, someone else will, so... what are we gonna do to stop the guys who did this?"

The co-creator of the Machine along with Harold Finch, and the founder of IFT.

  • The Alcoholic: As his marriage falls apart and he becomes more disillusioned by his work, Ingram falls into alcoholism.
  • Break the Cutie: When we first meet him, he's a carefree, happy-go-lucky sort of guy with a heroic streak. That was in 2002. By 2010, he's had an affair, divorced from his wife, haunted by the Irrelevant Numbers, his and Finch's friendship is being driven apart by their disagreement over the Irrelevant List, and he's become an alcoholic.
  • Big Good: Filled this role before The Machine did. He decided to start trying to save the numbers way before John Reese took up his position at Team Machine, even when Harold disagreed and actively opposed him and set up the basic original infrastructure for Team Machine to utilize, i.e. the Library.
  • Broken Ace: A charming man and an award winning software engineer but also plagued with a drinking problem and a conscience.
  • The Charmer: Was shown to have this talent.
  • Chronic Hero Syndrome: Haunted by the Irrelevant List, he sought out to stop what was going to happen to them. Some he saved. Others he didn't.
  • Death by Origin Story: His (preventable) death was the catalyst that started Finch on his obsession with saving the Irrelevant Numbers.
  • Deadpan Snarker: Especially around Harold.
  • Expy: Of Steve Jobs, according to the casting call.
  • Heterosexual Life-Partners: With Finch.
  • Honor Before Reason: He wanted to go public about The Machine because he felt it was the right thing to do, and wouldn't listen to Finch when Finch said he thought that the government was killing off people connected with The Machine.
  • Make It Look Like an Accident: Nathan's death makes it look like he's just collateral damage of a terrorist attack.
  • The McCoy: To Finch's Spock (before his death and Finch's subsequent becoming something of a McCoy/Spock hybrid.)
  • Only Friend: To all appearances, Ingram was Finch's only friend.
  • Posthumous Character: Is dead when the series starts, and is only seen in flashbacks.
  • Sharp-Dressed Man: He is almost always in a nice suit, in and out of the office.
  • Suspiciously Similar Substitute: He's this to John Reese without the military experience. Both were Finch's Only Friend, have ruined personal lives and were the ones putting their lives on the line to try save the Irrelevant numbers.
  • Talker and Doer: The talker and face of his and Finch's company.
  • Too Good for This Sinful Earth
  • What the Hell, Hero?: Gives one to Finch in a flashback, which forms part of the reason Finch ends up recruiting Reese to track the 'irrelevant' numbers.
  • What You Are in the Dark: A guy who wants to help, with no plan, no backup, and no weapon worth a damn.
  • Wide-Eyed Idealist: In contrast to Harold's cynical personality and initial willingness to let the numbers on the irrelevant list die, Nathan believed he could make a difference by saving them from their fate and coded the Contingency so the irrelevant list would come to him even after the Machine was black boxed.
  • Your Cheating Heart: Though still married, he was carrying on an affair with a graduate student until The Machine exposed it to Harold.


Zoe Morgan
Played by: Paige Turco
Introduced in: "The Fix"

A "fixer" and the occasional lover of John Reese. They meet when Reese and Finch helped saved her when The Machine gave them her number. She returns the favor by helping them out from time-to-time with persons of interest cases that require her particular skills.

  • Action Girl: She has no qualms about getting into physical fights or infiltrating buildings, but would rather leave the violence to people with better skills than her such as John.
  • Cool Car: She has a sweet Audi RS7.
  • Dating Catwoman: Her relationship with Reese has shades of this.
  • Deadpan Snarker: And How! Her temporary marriage to John was a glorious example of this.
  • Femme Fatale: Especially around John; she flirts shamelessly with him and is certainly morally dubious...but she's a good person at heart.
  • The Fixer: Her job.
  • Friends with Benefits: Her relationship with Reese turns out to be this.
  • Guile Heroine: Qualifies due to her stalling of the murderous pharmaceutical executive and counting on John to break out of his handcuffs with the paper clip she slipped him and get to her in time.
  • Hero of Another Story: Appears a couple of times when her own job just happens to intersect with Team Machine, but they're not Working the Same Case. In one episode, she steps into a hotel lift to find Reese dressed as a bellhop. Both are too professional to insist on explanations; they just enjoy the encounter.
  • Honorary True Companion: Though she is trusted as much as Carter and Fusco, she always returns to her job after helping Team Machine out.
  • I Was Never Here: In "Bury the Lede":
    "It was a pleasure meeting you, but it's a shame we never met."
  • Lady in Red: As befits her Femme Fatale nature, she's oft seen in a red overcoat.
  • Nerves of Steel: Extremely so. Very few situations can make Zoe flinch.
  • Only in It for the Money: How she presents herself to the world; it seems she actually has a Hidden Heart of Gold.
  • Put on a Bus: As Paige Tuco has signed up to NCIS New Orleans, it is unlikely we will see her for some time.
  • Ship Tease: With Reese just about every time they're on screen together. Seemed to have been elevated to Love Interest as of "Booked Solid"; confirmed in "Lady Killer."
    Shaw: I clocked you and Zoe right off the bat...
  • The Social Expert: As a fixer, her job is to understand human interactions to allow her how best to handle some situations.


Grace R. Hendricks
"Our journey starts here. And any mystery around the corner, we can discover together."
Played by: Carrie Preston
Introduced in: "No Good Deed"

Harold Finch's fiancée, who believes he is dead. She still lives in New York, working as an illustrator. Although Finch is unable to see her, he will still occasionally sit in Washington Square Park, near her home, using an app that alerts him in case he ever gets closer than hundred meters around her.


Jessica Arndt
"Tell me to wait for you and . . . say those words, and I will."
Played by: Susan Misner
Introduced in: "Pilot"

Reese's deceased lover. After Jessica's relationship with Reese ended, she married another man, but remained in contact with Reese. She is eventually killed by her husband during a domestic dispute.


Leon Tao
Played by: Ken Leung
Introduced in: "The Contingency"

Leon: Man. I so don't get paid enough for this crap.
Reese: We don't pay you anything, Leon.

A former forensic accountant and three-time Person of Interest. He is targeted to die by the Aryan Nation, the Russian Mafia and Nigerian fraudsters and is always saved by the timely intervention of Reese and Finch. He returns the favor by helping them out with persons of interest that require his skills.

  • Asian and Nerdy: It doesn't get more stereotypical than being Chinese and an Accountant.
  • Butt-Monkey: Tends to have bad things happen to him, such as getting in the List three times.
  • Did Not Get the Girl: He's pretty upset over it too, despite the fact that she was being paid to help kill him.
  • Forensic Accounting: Extremely good at it, picking apart the motivations for the conspiracy to kill the energy company owner in "Critical."
  • Honorary True Companion: Despite his general stupidity, he is quite loyal to Team Machine. So much so that they even trust him to save Shaw from Northern Lights.
  • Pay Evil unto Evil: Loves stealing money from criminals (e.g. Aryan gangsters, Nigerian scammers, etc.), even though it keeps getting him into trouble.
  • Plucky Comic Relief: Almost every scene he's part of is funny in some way, shape, or form.
  • Taught by Experience: When he realizes that two toughs are planning to kill him rather than just beat him up, he correctly predicts that Reese is about to break down the door and save the day. This is the third time his life has ended up in danger and he is able to spot the pattern.
  • Too Clever by Half: The brains part is debatable, though. Sure, he's got the IQ and math skills, but the good judgement...
  • Too Dumb to Live: Who would be dumb enough to have his number appear again 6 episodes later, and then again 11 episodes after that? He would.
    Reese: "Well who would be dumb enough to get in a life threatening situation again?"
    [Cue Leon being thrown out of a window.]
  • What Happened to the Mouse?: He disappears after season 2, leaving one to wonder where he went. Given his general propensity for getting into trouble, it doesn't speak highly of his chances.


Taylor Carter

Played by: Kwoade Cross, Tre Jamison (2008)
Introduced in: "Get Carter"

The son of Paul and Joss Carter.

  • I Have Your Son: Elias kidnaps him to get Carter to hand over the Mafia Dons. Reese promises to rescue him and she refuses.
  • Parental Abandonment: His father suffered from a nasty case of untreated PTSD and, while he very much wanted to be involved in Taylor's life, he was only well enough when Taylor was a teenager. Taylor doesn't seem particularly bitter about it and he ends up living with Paul after Carter dies.
  • Satellite Character: Only important because of his relation to Carter, and drops out of the story shortly after her death.
  • You Are Not Alone: Constantly reminds his mother of this.



Paul Carter

Played by: Laz Alonso
