    Captain Moreno 

Captain Moreno

Played by: Monique Gabriela Curnen
Appeared in: "Wingman"

  • Must Have Nicotine: She is trying to quit smoking. Her nails have been bitten off as a result.
  • Reasonable Authority Figure: She doesn't put up with Reese repeatedly kneecapping people, but she does give a lot of leeway when it comes to getting the job done.
  • What Happened to the Mouse?: in Season 4, she's only seen on screen in "Wingman," though she is referred to in other episodes and apparently still in charge at the 8th Precinct.



Detective Calvin "Cal" Beecher

Played by: Sterling K. Brown
Introduced in: "Til Death"

An NYPD narcotics detective who worked at Joss Carter's precinct.

  • Dirty Cop: He has several investigations into him by Internal Affairs and seems linked to the dirty cops in HR. Ultimately averted. Beecher is a good man and good cop who happens to be the godson of the head of HR.
  • He Knows Too Much: Was killed because he got close to identifying head of HR, and learning that Szymanski was clean and refused Elias' money.
  • Love Interest: Briefly, for Carter.
  • Sacrificial Lion: As the godson of the head of HR, his death shows not only can anyone die, but HR will not let anything stand in their way.
  • Scary Black Man: Played with in that it isn't clear at first if he's a good or bad person. Ultimately Averted. Good person, unfortunately his godfather is corrupt.
  • Red Herring: After multiple suggestions that he's working for HR, it's ultimately revealed he's not.
  • Unwitting Pawn: To the head of HR, used to discredit another good detective.


Det. William "Bill" Szymanski

Played by: Michael McGlone
Introduced in: "Witness"

A detective in the organized crime division at the NYPD 8th Precinct who assisted Joss Carter with cases involving mob families and other organized crime.

  • Dirty Cop: Averted; he was set up to look like one by HR, but Carter proved his innocence. Elias even says he tried to bribe the man, but he wouldn't break his morals.
  • The Generic Guy: Appeared mostly when a detective other then Carter and Fusco was needed.
  • Sacrificial Lion: Killed by HR for continuing to pursue the Russian Mob, whom HR wanted to solve their money problems.
  • Screw the Money, I Have Rules!: After his murder, Det. Beecher asks imprisoned Elias if Szymanski was on his payroll. Elias says he offered Szymanski money, "and he threw it in our faces."


Dani Silva

Played by: Adria Arjona
Appeared in: "Point of Origin", "M.I.A."

"In high school, I was a runner for a gang. Where I'm from, it's not a choice. Once you're in, it's either knocked up or locked up."

An Internal Affairs officer first met when her number comes up while she is operating under cover to identify a Brotherhood mole in the NYPD. She becomes a recurring ally.

  • Action Girl
  • Composite Character: Vaguely resembles a mashup of Carter and Shaw.
  • Dark and Troubled Past: She was born in a poor, crime ridden neighborhood and would've been doomed to a life of crime if she wasn't arrested and rescued by her mentor.
  • Deadpan Snarker: When she pulls her gun on a serial killer that was attempting to sneak up on her in a bathroom:
    "It's polite to knock."
  • Hypercompetent Sidekick: She's one of the few people able to outplay Reese in a tactical exercise, and she also figures out he's a highly trained ex-military officer.
  • Internal Affairs: A rare positive (and effectual) example.
  • The Mole: she's a fully-trained undercover cop posing as a police academy cadet.


Dr. Iris Campbell
Played by: Wrenn Schmidt
Introduced in: "Prophets"

The therapist "Detective Riley" has mandatory sessions with after his forth kneecapping.

  • Betty and Veronica: Mildly, with Zoe Morgan.
  • Florence Nightingale Effect: To her credit, she is keenly aware of this trope and fires Reese as a patient because of it. She still ends up planting one on him.
  • Heroes Want Redheads: Reese certainly does.
  • Rescue Romance: With Reese, who saves her from a drive-by shooting at one point.
  • Ship Tease: In "Guilty" between her and Reese. First there's the awkward attempt at a hug and then Zoe makes a comment about it.
  • "Shut Up" Kiss: She gives one to Reese, but it was to shut herself up.
  • The Shrink: Type 3. She gives Reese some much needed therapy.


Detective Joseph Soriano

Played by: Ned Eisenberg
Appeared in: "In Extremis", "B.S.O.D."

  • Back for the Dead: Reappears after two seasons, only to be unceremoniously murdered by Samaritan.
  • He Knows Too Much: He's determined to investigate Dominic's death. Samaritan nips that in the bud.
  • Inspector Javert: Is convinced Fusco is a Dirty Cop and is determined to take him down for Detective Stills' murder. He's not wrong exactly (Fusco used to be dirty, and Reese killed Stills with Fusco's gun so that it would look like Fusco did it). By the time he reappears, he seems fixated on putting Fusco away however he can; he looks really smug as the FBI seems to be going towards accusing him of murdering Dominic and Elias, and then is visibly confused and perturbed when they change tune and recommend Fusco for a commendation instead (courtesy of Samaritan).
  • Internal Affairs: His job.
  • Killed Offscreen: By Samaritan, using his pacemaker.


Detective Bernie "Sully" Sullivan, Ret.

Played By: Dan Hedaya
Appeared in: "The Fix"

A retired detective who investigated the murder of Marlene Elias.

  • He Knows Too Much: Elias kills him for continuing his investigation into Elias' mother's death.
  • Nice Guy: A pleasant man who's willing to help Carter's investigation.
  • That One Case: The Marlene Elias case. He had the killer, Vincent DeLuca, dead to rights with his fingerprints before the jury got bribed and DeLuca walked.



Special Agent Nicholas Donnelly
Played by: Brennan Brown
Introduced in: "Root Cause"

"We finally caught him . . . the Man in the Suit."

An FBI agent whose intent was to expose the CIA for their illegal actions and crimes and track down "The Man In The Suit".

  • FBI is Good: Is honest and dedicated towards stopping crime.
  • Dramatically Missing the Point: Thinks Reese works for Elias as a hitman, instead of working for Finch as a Vigilante Man.
  • Inspector Javert: He's dedicated to pursing Reese to the point of never considering Reese, though committing illegal acts, is doing good.
  • Jumping Off the Slippery Slope: He increasingly shows shades of this in his pursuit of Reese under the assumption that Reese is a Psycho for Hire. Carter calls him on this in "Prisoner's Dilemma".
  • Properly Paranoid: When he finds out that the DNA samples and fingerprints he sent out for testing did not match "the man in the suit", he correctly assumes that they were tempered with. Subverted right afterwards when he puts Carter in charge of the interrogations because he does not trust anyone else on his team. Double Subverted when he informs her that he believed she was the mole and kept her close for that reason.
  • Reasonable Authority Figure: He starts out as one, but turns into a Well-Intentioned Extremist as the investigation continues.
  • Revealing Skill: He sticks Reese with a bunch of dangerous prisoners at Riker's, hoping that he'll exhibit skills that will peg him as former military and confirms Donnelly's suspicions.
  • Sharp-Dressed Man: Donnelly is always seen in a nice suit.
  • Silly Rabbit, Idealism Is for Kids!: He doesn't believe Carter when she tries to tell the truth about Reese and what he is doing, believing that she was tricked.
  • Sympathetic Inspector Antagonist: He thinks Reese has become a CIA psychopath-turned-mob hitman and is trying to bring him in.
  • Well-Intentioned Extremist: At one point in "Prisoner's Dilemma," he's willing to put a potentially innocent suspect (Reese) at risk of being killed in a prison riot just to see if he's trained in unarmed combat.
  • What the Hell, Hero?: He's furious at Carter for helping Reese, saying that he's playing a long con on her.
  • Wild Mass Guessing: His theories as to what The Man in the Suit is up to seem to come off as this in later episodes, with theories about Chinese intelligence agencies. They'd be amusing if it wasn't for the fact that he honestly believes them and thinks they justify whatever dubiously legal things he has to do in order to bring The Man in the Suit in. Though oddly, much of what he says is actually true about Decima Technologies, its just that Reese is not working for them. Almost everything he said about Reese was actually true about Kara Stanton, who kidnaps Reese almost immediately afterwards.
  • You Monster!: He throws this accusation at Carter and Reese.
    "Your friend is nothing more or less than a highly trained murderer. You don't wind up with that job by accident. He chose that life. He chose to become the monster he is."


Special Agent in Charge Brian Moss

Played by: Brian Hutchison
Appeared in: "Dead Reckoning", "Booked Solid", "Proteus"




Supervisory Agent Terence Beale

Played by: Keith David
Appeared in: "Truth be Told"

Reese's former boss who oversaw the CIA's Special Activities Division (SAD), therefore being the boss of Mark Snow, Kara Stanton and John Reese. He was responsible that Reese was selected to serve in the SAD due to his impressive performance during training.

  • Badass Baritone: It's Keith David, for God's sake; the man's voice is legendary and Beale is an experienced CIA man.
  • I Owe You My Life: To Reese.
  • Shout-Out: His name is a reference to Thomas J. Beale, the purported author of the Beale Ciphers.
  • Reasonable Authority Figure: He's largely benevolent, or at least the most benevolent portrayal of a CIA agent in the show besides Reese. Beale decides to leave Reese out of his report, and prevents the CIA from hunting him down.



Agent Mark Snow
"Don't forget, you're behind enemy lines here."
Played by: Michael Kelly
Introduced in: "Number Crunch"

The alias of a CIA case officer, at one time partnered with Tyrell Evans. He was John Reese and Kara Stanton's handler in the CIA. He also claimed to be Reese's best friend.

  • Better to Die than Be Killed: Reese reminded him that even if he ran back to the CIA they will still consider him compromised and lock him up so he settles for killing Stanton.
  • CIA is Evil: He is a very amoral man.
  • Consummate Liar: Probably the only consistently truthful statement he ever made was his name.
  • Deadpan Snarker: Has quite a tongue on him.
  • Deceased Fall-Guy Gambit: After Snow dies, the FBI stops chasing Reese because they decide that Snow was the "Man in the Suit" all along.
  • Dying Moment of Awesome: Jerkass as he may be, he does die delivering some Karmic Death upon his captor.
  • Driven to Suicide: Minor variation, he initially planned to make a break for a safe house run by the CIA to get his bomb vest defused but John mockingly pointed out they wouldn't welcome him back with open arms and probably torture him, demanding an explanation about his long absence so instead Snow heads to Kara Stanton's car to kill her in the blast of his bomb vest when it goes off.
  • Even Evil Has Standards: Shoots down L-O-S's suggestion of killing Carter, stating they "Can't go around killing cops." before black-bagging him, although this may instead be a case of Pragmatic Villainy. Also is utterly terrified about Kara, making a special effort to hunt her down when she shows up in New York.
  • Explosive Leash: How Stanton makes him work for her. Doubles as Laser-Guided Karma.
  • Face Death with Dignity: He is perfectly calm in his last moments. Granted, at that point he'd basically been Kara's slave for months so he may have seen it as a relief. Plus, he was taking Kara with him.
  • Famous Last Words: "You were right, Kara, about me being dead: I'm gonna be great at it." Doubles as a Pre-Mortem One-Liner
  • Jerkass: Not in a abrasive sense but in a much more slimy fashion when he ran John and Kara. However, with Carter, it qualifies fully due to his increasing failure to trap and kill Reese in which he suspects she has a hand in helping him get away
  • Meaningful Name: His surname is Snow, which is appropriate considering his status as a Consummate Liar.
  • Pet the Dog: When in New York, he allows Reese out of the apartment they're holed up in with a prisoner to go have a drink at a bar.
  • The Men in Black: He runs them, giving out missions which would never be officially sanctioned.
  • Smug Snake: Snow is very confident, amoral and ruthless but he lacks the competency of his underlings. The only thing he ever did correctly was die.
  • Taking You with Me: To Stanton.
  • Teeth-Clenched Teamwork: With Reese thanks to the Explosive Leash on both of them.
  • Those Two Bad Guys: With the late Agent Evans.
  • You Have Outlived Your Usefulness: Seems to be a favorite tactic of his, as he has so far done this to three of his operatives.


Agent Tyrell Evans

Played by: Darien Sills-Evans
Introduced in: "Number Crunch"

The alias of a CIA field officer, partnered with Mark Snow. He assisted him in trying to "retire" Reese along with other assignments. He was shown to be an expert sniper and good with computers. He appeared many times with his partner, Snow.
