Missing info from: all episodes since “Panopticon”
|“||At first, I uh, I thought I was helping to clean up the streets, you know? 'Who's gonna miss some drug money from a low-life dealer'. Then it became 'Who's gonna miss the dealer'....Then you find yourself in a situation, a bad situation that you shouldn't be in. I killed people, Carter. I was a dirty cop.||”|
Detective Lionel P. Fusco is a homicide detective in the New York City Police Department (NYPD). John Reese has turned him into his own source of information and support within the police department. He has a son, Lee, whom he is close to.
Life as a corrupt cop
Fusco was originally part of the 51st NYPD precinct, and good friends with Detectives James Stills and Louis Azarello. In 2004, Fusco's wife files for divorce and demands full custody of their son, kicking Fusco out of their house. Stills meets with Fusco at a bar and offers to let him stay at his house, which Fusco accepts.
Stills and Azarello begin to manipulate and persuade Fusco to join them in their criminal activities. Fusco is reluctant to help them, but still teaches Azarello how to cover up their killing of a drug dealer who was uncooperative in a deal gone bad. Fusco is later horrified to see Stills and Azarello's killing of several people in a second drug rip off. Fusco shoots another dealer in self-defense, and Stills gives him some of their drug money, welcoming him to their crew. (“In Extremis”)
Fusco, however, is not opposed to getting his hands dirty when his fellow officers are hurt. Fusco confesses to a shooting while being questioned by a department psychologist, and tells the story of how when a 24-year old rookie cop was gunned down by a drug dealer named Jules, Fusco exacted revenge by catching Jules off-guard without protection and shooting him twice in the chest, later making it appear justified. Fusco claims that Jules got what's called "the Devil's share", or a cruel form of karma in his eyes. (“The Devil's Share”)
Involvement with Reese and Finch
Fusco first comes into contact with John Reese when he, Stills, and Azarello become part of a gang led by ADA Diane Hansen, which Reese was attempting to take down. After catching him, Fusco drives Reese to Oyster Bay to kill him, but Reese escapes from the car and takes Fusco's sidearm. With it, Reese later kills Stills in an armed standoff and hides his body in the trunk of Fusco's car to link him to the crime and blackmail him into working for him. Reese orders Fusco to dispose of Stills' body, and Fusco becomes Reese's source of information inside the NYPD. (“Pilot”) He comes under investigation by IAB for his actions and reluctantly aids Reese in identifying the hit man who killed the Whittaker family through one of his confidential informants. (“Ghosts”)
After Fusco attempts to have Reese killed a second time in some dealings with the Torrerós drug cartel, Reese blackmails the 8th Precinct's corrupt police captain in order to get Fusco transferred to the Homicide Task Force and partnered with Detective Joss Carter, who was hunting Reese at the time. Fusco is then ordered to keep Carter's investigations directed away from Reese and to keep Reese informed of what Carter is doing. (“Cura Te Ipsum”)
Reese later visits Fusco in a coffee line to find out what he learned about Carter's investigation and to get his help looking for clues in the investigation of a missing boy. While usually reluctant to help, Fusco offers Reese any help he can to save the missing kid, saying the case is about a kid and whatever else he is, he's still a cop. However, Reese just walks away. After learning that Carter is investigating the murder of Christina Rojas, Fusco offers to help Reese by solving Rojas' murder, suggesting it could help him find the missing boy. Fusco is able to identify the killer using a security camera and one of the descriptions Reese gave him and links the killer to Coldfield Holdings which he sends to Reese. Fusco and Carter later go to the money laundering headquarters and find the gang "gift wrapped" for them by Reese and take them into custody. (“Judgment”)
While providing Reese with more information involving another case, Fusco meets Harold Finch, who is initially uncomfortable about Reese's decision to work with Fusco, but eventually gains his trust. (“Witness”)
As time goes on, Fusco does demonstrate a loyalty to Reese. Their relationship is comical; their conversations are filled with dry humor and witty annoyance. Carter later begins working with Reese and Finch as well, (“Legacy”) but she and Fusco do not know that they are working for the same people for the remainder of the season.
Reese later asks Fusco to trail Finch to find out more about him. (“Legacy”) Fusco eventually meets with Reese and shows him papers on Finch's Harold Wren identity, one of many aliases Fusco has found for Finch. Fusco is unable to determine who Finch really is and comments that Finch uses so many aliases he doubts Finch even knows anymore. (“Wolf and Cub”)
Fusco helps Reese and Finch on another case, where he meets up with his friend, corrupt police officer Patrick Simmons, for information on a smuggler involved with the crime organization HR. When Fusco is later caught destroying the file of an undercover cop and taken out to be executed by Ian Davidson, a corrupt IAB detective, Reese shows up just in time to kill Davidson and save Fusco's life. Fusco, who has grown to enjoy being a good cop, wants to report the shooting which would be ruled self-defense due to the circumstances, but Reese destroys Davidson's phone and asks Fusco to get HR to cover up the killing so he can remain undercover for Reese. Fusco reluctantly complies, burying Davidson and meeting with Simmons who tells Fusco he belongs to HR now. (“Blue Code”)
After Carter refuses his calls, Reese turns to Fusco to help him investigate the two Jordan Hesters. Fusco interrogates Kyle Morrison who claims to be the victim of a similar crime and identifies the female Jordan Hester as the fake. On Reese's orders, Fusco rescues Finch and identifies the fake Jordan as Tara Verlander. The two track down Tara and Fusco has her arrested by Detective Desmond Franklin, stating that Tara's arrest is too high-profile for him to make due to a possible connection to HR. With Tara's arrest exonerating Kyle, Fusco secures his release from prison and tells him to go home to his daughter who just turned two. (“Identity Crisis”)
When Elias starts making his move against the Mafia Dons, Fusco is asked by Simmons for anything he knows on Reese and is warned to take a few days off as Homicide will be "busy". Not sure who to trust, Carter turns to Fusco for backup with protecting the three remaining Dons and repeatedly refuses his requests to call for backup. As Elias works to break in, Don Vittorio Zambrano reveals Fusco is a dirty cop to Carter then takes a gun from Fusco to make a deal with Elias. Though Zambrano expects Fusco to side with him, either Carter or Fusco shoots him dead and they enter a standoff with Elias and his two men after they break in. Due to the intervention of Finch, the HR cops outside leave and soon after honest cops arrive. Fusco reveals he called for backup from honest cops and Elias and his men surrender to Carter and Fusco. (“Flesh and Blood”)
After the fall of Elias, Captain Artie Lynch begins working with Fusco to fund HR operations by shaking down criminals for money. As part of this, Fusco is sent to meet with Tommy Clay to get HR's cut of his robbery operation only to find Reese there and HR's two men dead. Lynch has a hard time believing Fusco's story but agrees to look for the fence Tommy will use for the stolen platinum. At a boxing gym, Lynch murders Tommy's girlfriend Ashley and beats on the tied-up Reese. After Lynch goes to shoot Reese, Fusco shoots him through the back, killing him to protect Reese. Fusco releases Reese and tells him that as he killed Lynch with Ashley's gun, he can make it look like Lynch botched the job and continue his undercover work without suspicion for Reese. (“Matsya Nyaya”)
After getting the number of a POI being stalked by her husband, Finch calls upon Fusco for help as he doesn't want to involve Reese and Carter is busy with Agent Donnelly. Fusco loses Sarah and Finch calls him off the case. Fusco later warns Reese and Finch that the Transit Police have arrested Sarah, causing them to realize she's in trouble. (“Many Happy Returns”)
While Reese is following Finch, Fusco calls him to tell Reese that Simmons has set up a meeting for him with HR's leadership. However, Reese is more interested in following Finch and Fusco is unaware that Carter is suspicious of him. When Henry Peck is later arrested, Fusco listens to him explain how he ended up in the situation and his theories about a machine the government is using to spy on everyone. Thinking Peck is simply crazy, Fusco leaves. He later watches as Terney talks to Carter about a John Doe found next to a burned-out cab and calls Reese to tell him that the meeting with HR's leadership will occur in three days. Reese promises to be ready before the two banter briefly about Reese's investigation into Finch and hang up. (“No Good Deed”)
Fusco contacts Reese to tell him that Simmons is going to bring him to a meeting with the HR leaders, but Reese just asks for his help with Caroline Turing. Simmons later escorts Fusco to a restaurant where he meets HR's leaders: Councilman Seth Larsson, New York Police Department detective Sam Romano and New York Metropolitan Transportation Authority Police captain Peter Lewis. After being teased about his being a dirty cop, Fusco witnesses the three order Simmons to kill a target they've been hired to target while Fusco will run interference with the Homicide Task Force. Though Fusco is denied the name of the target, he gets a look at their picture and recognizes her as the woman Reese ordered him to look into. After leaving the group, Fusco calls Reese and warns him of the development, telling Reese that within 48 hours, Turing will be dead.
Later, as the FBI tracks Reese using their real-time crime center, Fusco joins them but is constantly texting while HR closes in on Reese and Turing. Carter notices this and confronts Fusco in the bathroom as he's on the phone with what she believes to be HR but is really Finch. Fusco tells Carter that he's undercover in HR for "the Man in the Suit" and describes Finch to her, causing Carter to realize he's telling the truth and they are working for the same person. After being told by Finch Reese needs their help, Fusco tells Carter he knows who HR's mole is along with the entire membership and they will take them down once this job is finished.
As Reese gets cornered by Simmons, Jablonski and another man, Carter and Fusco rescue him, laying down covering fire for Reese to get into their car. The three chase Jablonski and his partner while the detectives question Reese on his separate activities with them. Reese deflects their questions before ordering Carter to slow down. Once she has, Reese detonates a bomb in the two HR cops car, killing them before leaving to meet up with Finch. Later, Fusco emails everything he has on HR to Donnelly anonymously, including the identity of the mole. (“Firewall”)
After receiving a number from the Machine, Reese contacts Fusco who identifies the social security number as belonging to Leon Tao. Fuso is able to use the anti-theft system on Tao's car to get his location for Reese. Fusco questions if Tao can help them find Finch and tells Reese he doesn't want to find out what Reese is like without Finch.
Reese calls Fusco after making sure Tao would be arrested to have Fusco look after him. Fusco is annoyed when he discovers Carter is working on the Alicia Corwin murder, but agrees. Tao later escapes the police station and Fusco tracks him to the impound yard where he is trying to retrieve his car. Fusco and Tao are captured by Aryan Brotherhood gang members Tao stole money from before Reese arrives to save them. After Reese is able to take control of Byron's attack dog, the three are able to escape with Reese teasing Fusco about his predicament. Fusco and Carter later arrest Titus, Byron and the other surviving Aryan gang members. (“The Contingency”)
A day after Finch's disappearance, Reese meets with Carter and Fusco in a bar. He tells them his belief that Hanna Frey is in fact Root and he and Carter will be investigating her disappearance. Reese orders Fusco to continue to investigate Alicia Corwin's murder and the person who is messing with the investigation. Before leaving, Reese leaves Bear in Fusco's care and gives him Finch's forced pairing program to help.
While talking to Carter about the search, Fusco notices Hersh and grows suspisous of him. Fusco finds Corwin's hotel room and is able to remove a few belongings from it including pictures of Finch and Denton Weeks. Staking the hotel out, Fusco spots Hersh and uses a forced pairing of his phone to eavesdrop on a conversation between Hersh and Special Counsel. Fusco learns of their search for Denton Weeks who has disappeared. Fusco contacts Reese and tells him he thinks Root took Weeks too. Fusco is able to locate Weeks' mistress' cabin in Relton, Maryland, helping Reese to find and rescue Finch. After the case, Carter and Fusco go out for a drink together. (“Bad Code”)
After Finch's rescue, Fusco turns the Alicia Corwin case over to Carter, not wanting anything more to do with it. Reese later calls him to protect Sofia Campos for him as he tracks down Paul Romano's killer. While in the bathroom, Sofia gets a call from her boyfriend Jack Hughes and gives Fusco the slip to meet up with him. After being warned by Finch that Jack is part of the operation that killed Romano, Fusco rushes to Sofia's rescue, stopping Monty Spencer from shooting her. Monty overpowers Fusco, but Carter and Reese body-slam him with his own car. Fusco then arrests Monty for Paul Romano's murder and the kidnapping and attempted murder of Sofia. (“Masquerade”)
After getting the number of Riley Cavanaugh, Reese has Fusco stake out George Massey's bar. During his stakeout, Fusco orders drinks then gives them to the man next to him at the bar to keep up appearances. George eventually takes off and Fusco warns Reese and Finch. (“Triggerman”)
Agent Donnelly and the FBI arrest over 75 dirty cops working for HR based on the information Fusco gathered while undercover. While Carter congratulates him, Fusco is worried due to his past as a dirty cop and a member of HR meaning he could be arrested too. After getting off the phone with his son, Fusco is threatened by Simmons who saw him helping Reese when HR tried to kill Root. Simmons tells Fusco that HR is down but not out and their boss is setting something up to protect HR's upper management. However, Simmons warns Fusco that the FBI are chasing something that could still bring all of HR down and he wants Fusco to find and destroy it. Simmons tells Fusco that if he doesn't Fusco will end up in prison and lose his son. Simmons promises to let Fusco out of HR if he does this one last thing for them and leaves.
Fusco later meets with Reese and Carter in a park where he lies that he hasn't seen Simmons since he rescued Reese from him. Reese asks him to keep an eye out for Simmons and anything he can find on HR's boss and promises to have Fusco's back, but Fusco is left troubled after looking at a picture of his son on his phone. Fusco later listens to an interrogation of Maxine Angelis and learns of Vittorio Zambrano's ledger that could've exposed HR's head. Reese calls Fusco to talk to Simmons to try to find the head of HR, but Fusco lies that Simmons doesn't know who it is and searches through Christopher Zambrano's property listings for a place the ledger could be located.
After Reese and Maxine are captured by Bogle and Pitt after finding the ledger, Finch calls Carter and Fusco to rescue them. The two former FBI agents realize the two are there without backup and a gunfight ensues. Reese subdues both men and Fusco takes the ledger from Maxine to turn over to the FBI. Before turning it over, Fusco removes the pages with his own name and Simmons and gives Simmons his page. Simmons tells Fusco that "once your in HR, you never leave" and that he's not the biggest threat to Fusco's son, Fusco himself is. (“Bury the Lede”)
Fusco is called in on the murder of Dusan Babic who was shot twice in the back at close range. All Fusco finds on him is Carter's business card with a mysterious code on the back so Fusco calls her and gives Carter the card without telling anyone else what he found. Reese later calls on Fusco to watch over Amy who is being threatened by snipers working for Alistair Wesley to force Doctor Madeleine Enright to cooperate with his plot while Reese is forced to share a drink with Wesley. Upon his return, Reese has Fusco create a distraction so that he can slip Amy a cell phone and guide her to safety. Fusco does so by harassing a police officer patrolling the park. As he leaves, Fusco tells another cop he assumes to be the man's partner to send his apologies but learns the man he accosted was not a real cop. Fusco returns in time to distract the fake cop, allowing Reese to overpower him and rescue Amy. (“Critical”)
While working the case of Sabrina and Daniel Drake, Reese tries to call Fusco twice but he ignores his calls. Fusco's behavior draws the suspicions of Reese, Carter and Finch, particularly after Fusco removes the battery on his phone so he can't be tracked. Fusco's behavior ends up being because he's started dating a woman named Rhonda and wants to keep it a secret, causing Finch to have to reach him through a restaurant phone to stake-out Sabrina. At Rhonda's request, Fusco takes her with him on the stake-out and saves Sabrina from Nestor Santiago. After locking the Drakes in the trunk of Carter's car, Fusco's secret is discovered and Reese and Carter leave him to take Rhonda home where she expresses interest in another date.
After dropping Rhonda off, Fusco goes to the Drakes' house to provide backup against the hit men the couple have hired to kill each other. During the confrontation, Fusco is shot in the chest but is wearing a bullet-proof vest and survives. Fusco recovers in time to shoot Santiago and save Carter. As the Drakes, Santiago and the surviving hit man are taken into custody, Fusco expresses disgust over the fact that after everything, the Drakes got back together. (“Til Death”)
After HR decides to resume ties with Elias, Simmons demands Fusco take part in the meeting with Scarface alongside him and Bowman. After the meeting is set up, Fusco refuses to join causing Simmons to send him an email with a message saying "not all accidents are caused with a shovel" and a video of Fusco and Ian Davidson together. Fusco reluctantly agrees to join the meeting where Simmons offers up Luciano Grifoni, the last surviving Mafia don to Elias in exchange for him reestablishing ties with HR. Scarface agrees on the condition that HR take care of Grifoni themselves and Fusco and Bowman are assigned to the job. Nervous, Fusco calls Reese for help but Reese is unable to talk to him due to being in a fight with the Estonian mob. Reese later calls Fusco back, but Fusco lies rather than ask for help. As Bowman and Fusco confront Grifoni, one of Grifoni's men kills Bowman and Grifoni gives Fusco a message from Elias: to tell HR to go to hell. Fusco passes on the message to Simmons and seconds the message, ending his ties with HR. Moments later, Carter gets a call which she tells Fusco is an anonymous tip that a cop murdered Davidson. Fusco sees Simmons hanging up his cell phone as he walks away and realizes Simmons left the tip. (“C.O.D.”)
Entering the precinct, Fusco finds Carter talking to Detective Cal Beecher about the possible murder of Ian Davidson. Fusco become suspisious as Beecher brings up the possibility of an HR cop connected to a group from the Fifty-First Precinct being involved, the group Fusco had been apart of. Before Beecher can tell Carter any names, they are interrupted by Agent Donnelly. Fusco later asks another detective about Beecher, learning that he had a lot of money and had worked undercover narcotics, furthering Fusco's suspicions that Beecher works for HR. Fusco follows Beecher to a meeting with HR leader Alonzo Quinn, using a forced pairing of Beecher's cell phone to listen in as Beecher reports on activities committed by Peter Yogorov. Fusco is approached by Simmons who he angrily confronts about tipping off Carter about his role in Davidson's disappearance. Simmons tells him he hasn't tipped off Beecher yet about Fusco's role in Davidson's murder to which Fusco responds that Simmons crossed a line to where Fusco doesn't care anymore and threatens an unconcerned Simmons. Fusco realizes that Simmons being there is strange, but Simmons refuses to tell him why and orders Fusco to go home.
Fusco later receives a call from Carter who pretends Fusco is her mother to confuse Donnelly before telling Fusco to warn Finch that Donnelly is onto Reese and is tracking his phone. Fusco quickly warns Finch and agrees to do whatever he can to help Reese escape. At the bank, Fusco leads in officers to help secure the bank and tells Finch, Abby Monroe and Shayn Coleman that he has them covered so they can get out safely. However, Fusco is unable to help Reese who is captured by Donnelly along with Philip Chapple's three mercenaries. (“Shadow Box”)
After Reese's arrest, Finch contacts Fusco for help with Caleb Phipps. Fusco tells Finch that Caleb has a couple of minor arrests that Fusco calls "kid's stuff". The two then joke about the nature of high school. Fusco later calls Finch back to tell him that Caleb's brother Ryan died in front of him after getting hit by a train while drunk but finds it odd that the transit cop called for backup and then rescinded the call. Looking at Caleb's test scores, Finch realizes that the boy is actually hiding the fact that he is a genius and the two men ponder on why he would do such a thing.
Fusco visits Caleb's mother under the pretense of checking in on neighborhood break-ins and plants a webcam to spy on her apartment. He tells Finch that he thinks Caleb's mother is alcoholic and identifies two teenagers Finch photographed as being drug dealers formerly working for someone named Lorenzo but who now work for someone the narcotics division can't identify. On Finch's request, Fusco follows the dealers and tracks the drug money across town to a PO box where the mysterious drug lord will pick it up. Fusco and Finch are surprised when their various surveillance efforts bring them across the street from each other and witness Caleb picking up the money. Fusco is shocked to realize that Caleb is the new mysterious drug lord.
The next day, Finch calls Fusco after learning that Caleb is about to meet with his dealer. Fusco is impressed with Caleb's skill in avoiding detection and he and Finch follow Caleb to his meeting where they find him being threatened by Lorenzo. While Fusco prepares to intervene, Finch stops him and they watch Caleb agree to pay the drug money back. As they stake-out Caleb's apartment that night, Fusco suggests that Caleb's not in it for the money but revenge for his brother. Fusco shows Finch the transcripts from the night that Ryan Phipps died which show that the transit cop called for backup as Caleb claimed there were two attackers then cancelled the backup call and filed an accident one instead. Fusco suggests that Caleb's two dealers, Ronnie and Diego, killed Ryan and Caleb is out for revenge. After seeing Chris Beckner setting up a meeting regarding Caleb's revolutionary coding, Finch leaves Fusco alone to stake-out Caleb while he goes to spy on Beckner.
The next day, Finch tells Fusco that Caleb is transferring all of his money into a trust and discovers that Beckner is meeting with his investors at the same time that Lorenzo is expecting to meet with Caleb. Fusco promises to help Finch cover the two meeting and calls in the transit cop, Andrew Murphy to find out what he knows about Ryan Phipps' death. Fusco claims that Ryan's death is connected to a cold case he's investigating and Murphy finally tells him that when he questioned Caleb about his brother's death, he realized Caleb was lying about there being two other men there. Murphy tells Fusco that it was Caleb and Ryan alone and while drunk and bored, the two raced across the tracks in a game. Ryan was killed and Murphy decided to cover it up rather than let it ruin Caleb's life as nothing could bring his brother back. Fusco relays the information to Finch and stakes out where Lorenzo is waiting for Caleb. After seeing Lorenzo preparing to hunt Caleb down, Fusco tells Finch he'll take care of Lorenzo while Finch takes care of Beckner. After taking care of Lorenzo, Fusco arrives at the subway station in time to witness Caleb choose not to commit suicide after being talked down by Finch. (“2πR”)
Fusco receives a phone call that he hopes is Reese and is disappointed to learn is just Finch. Worried about his friends, Fusco offers any aid he can to breaking Reese out, but instead Finch assigns him to watch their next number. While annoyed at first, Fusco is excited to discover that the number is Karolina Kurkova and agrees to protect her. Finch later calls Fusco for a status update, but Fusco has been noticed by Kurkova who sprays him with mace and hits him repeatedly with her bag as Fusco tries to explain to her he's a cop there to help her. Fusco eventually gains Kurkova's trust and they end up on the run from Armenian gangsters with Kurkova refusing to go to a nearby police station. Finch contacts Fusco for help identifying Hersh and Fusco tells him that Hersh is the "government spook" that had been hanging around after Alicia Corwin was murdered. Fusco tries to ask Finch for some help with his own situation, but Finch just hangs up on him. That night, Fusco and Kurkova are cornered behind a car and Fusco insists Kurkova run while he holds the Armenians off but Kurkova refuses to leave. Armed with two pistols, Fusco engages the Armenians and manages to beat them. Kurkova later kisses him goodbye and tells him to call her. Fusco is left stunned until Finch calls to tell him that they have a situation and sends Fusco Carter's last known coordinates. (“Prisoner's Dilemma”)
The morning after Kara Stanton kills Donnelly and abducts Reese, Fusco calls Carter, worried as Donnelly has been found dead and Finch had sent him looking for Reese and Carter the night before. When Carter arrives, Fusco notes she's missing an earing which she quickly lies about. As Carter searches the wreckage for her earing, Fusco hands it to her, having found it and asks what's going on. The two meet with Finch who informs them about Kara Stanton, along with the fact that she's supposedly dead. After finding out that Stanton had Mark Snow steal a hard drive from a technology company, Finch asks for everything Carter has on the stolen hard drive and tells the two detectives that they need to find out what Stanton is doing and for whom to save Reese. Fusco is left worried when Carter mentions that when she saw Snow, he was wired to a bomb vest.
After Reese sends Finch a text message from an unknown number indicating he's strapped to a bomb vest, Fusco and Carter check it out and discover that the men were ATF agents called to a bomb threat at a nearby building. Arriving there, Carter gets a call from Finch who discovers that the 21st floor is a government cyber weapons lab and Stanton intends to steal one for the people she works for which would enable them to cripple a country. Unable to get past the police guards, Carter has Fusco and herself use the stairs to reach the 21st floor to Fusco's annoyance. The two reach the 21st floor in time to find Reese with an activated bomb vest and about to head to the roof to get away from innocent people. While Carter insists on trying to disarm the bomb, Reese refuses to let her as she has too much to lose which Fusco reiterates, reminding Carter of her son. Upset about their friend's impending death, the two cops head for safety as Reese heads for the roof.
Fusco and Carter wait outside of the building, watching the rooftop for the explosion. After it fails to go off, Fusco, not knowing Finch disarmed the bomb, wonders if it was a dud. A moment later, an explosion occurs around the corner and Fusco and Carter race to the edge of the neighboring street to find Stanton's getaway car destroyed after Snow sacrificed himself to kill her with his bomb vest. Two days later, Fusco watches as SAIC Brian Moss tells Carter that they have identified Snow as "the Man in a Suit" and officially closed the case. Fusco asks a clearly worried Carter if everything is alright but she just tells him "we'll see." (“Dead Reckoning”)
Fusco finds Carter continuing to investigate Davidson's disappearance and asks if she's still following up on the anonymous tip that a cop killed Davidson. Carter tells him she thinks a lot of cops had a reason to want an IAB detective dead and has remembered the disappearance of Detective James Stills who had also disappeared the year before. Carter asks about Fusco's past with Stills, but Fusco just tells her that they worked together a long time ago. Carter believes that two cops going missing in the same year with their bodies never being found means that something isn't right, worrying Fusco due to his connection to the two disappearances. They are then interrupted by a phone call from Finch about Logan Pierce. Fusco later finds Carter in the interrogation room continuing her investigation and attempts to tell Carter the truth about his past. Carter stops Fusco, telling him that while she trusts him if he says he's changed and considers him a friend, she is a cop first and will not protect him if his past comes back to haunt him. (“One Percent”)
Fusco watches as SAIC Brian Moss offers Carter a chance to join the FBI and asks if she will take the offer which Carter confirms. Finch later calls Fusco in to run surveillance on a hit team member at a hotel bar and Fusco warns Finch when the man goes on the move. On Finch's orders, Fusco follows two of the team outside and subdues them, recovering Charles Harris' body. Fusco then calls for backup to take in the hit men he and Reese captured while he takes Mira Dobrica back to the precinct. Fusco leaves Mira in an office and while he's distracted talking to two other cops, a final hit man sneaks into the office and strangles Mira. Fusco notices in time to shout a warning to Carter who shoots the hit man dead and saves Mira. Fusco then comments that Carter didn't miss all the fun after all. (“Booked Solid”)
Fusco and Carter are called in after the "death" of Sameen Shaw. While the patrol cop at the scene believes it to be a homicide, Carter and Fusco pass it off as an overdose or cardiac arrest and ask Leon Tao, pretending to be a paramedic, to take Shaw's "body" to the morgue. Tao asks Fusco for help in rolling the stretcher into the ambulance and while Fusco complies, he seems surprised to recognize Tao. (“Relevance”)
After Detective Bill Szymanski is framed as a dirty cop, Carter asks if Fusco knows anything about Cal Beecher being dirty. Fusco admits he doesn't, but warns Carter that while they took down a lot of dirty cops, HR is not yet finished and she may not like what she finds if she follows the money planted on Szymanski. Carter later follows the money and finds proof to exonerate Szymanski and thanks Fusco for his advice of following the money. Fusco privately warns Carter that this proves that HR had it out for Szymanski and to be careful they don't come after her next. (“All In”)
Fusco is approached by Carter who tells him that Beecher had given the information that led to Szymanski's arrest and eventual murder. After Carter tells him that she needs to know what Beecher knew if anything, Fusco promises to look into it. Fusco confronts Beecher in the men's bathroom, pointing out just how suspisous it is that the marked bills weren't placed into evidence when Elias' bodega was raided. Fusco implies that Beecher is a dirty cop while Beecher implies he knows about Fusco's past as one. Before the argument can go any further however, Raymond Terney breaks them up.
As Beecher visits Elias in prison, rattled by Fusco's accusations, Fusco waits outside and uses his previous forced pairing of Beecher's phone to listen in on and record Beecher's conversation with Elias. The conversation exonerates both Beecher and Szymanski, confirming that Beecher was set up rather than be a member of HR. Fusco plays the recording for Carter but tells her that they can't give it to IAB as its an illegal wiretap and she should let it go now that she knows Beecher is innocent. Fusco tells Carter that Beecher could be walking through a minefield and she needs to be careful before following him. Shortly after, they get a call for an officer needing help in Washington Heights which is where Carter knows Beecher to be. The two detectives rush to the scene to find Beecher dead and Fusco sadly leads Carter away from Beecher's body. (“Trojan Horse”)
Fusco attends Beecher's funeral where he threatens Simmons for his role in Beecher's death. Simmons is unthreatened and tells Fusco that he's only survived so long as he had protection he no longer has and his former friend Louis Azarello is being investigated for a dozen murder cases. Upon returning to the precinct, Fusco is approached by IAB detective Joseph Soriano for his role in Detective James Stills' disappearance. Carter tries to get a despondent Fusco to explain what's happening to her, but he reminds her of how she didn't want to know and refuses to share what's going on, instead telling Carter its better for her to stay away from him.
Soriano questions Fusco on his relationship with Stills and Fusco tells him that they came up through the ranks together until Fusco went to Homicide and Stills went to Narcotics. Soriano tells Fusco that he figured out that for Stills' crew to have worked, they had to have someone in the Homicide Division to cover for them and shows him a video of Azarello explaining their system, including how Fusco covered up the murders Stills' gang committed. As Soriano continues his interrogation, he accuses Fusco of not just covering up murders, but of being a killer himself. Soriano brings out stained carpet from Fusco's car, cell phone records showing he made a call from Oyster Bay and satellite imaging of four plots of disturbed ground in Oyster Bay as evidence that Fusco murdered Stills and buried his body. Fusco refuses to cooperate, but Soriano just tells him that he is going to search those plots and find Stills' body so he can arrest Fusco for Stills' murder.
In the men's bathroom, Fusco meets with Carter and tells her that he's going to answer her questions. Fusco explains that he didn't kill Stills but is still going down for his murder and deserves it due to the other bad things he's done. Fusco explains that he'd started out believing he was cleaning up the streets, but eventually became a murderer and dirty cop. Fusco insists that he's changed since he met Carter, Reese and Finch and he doesn't expect Carter to cover for him, but he just wants her to understand. Carter is horrified by Fusco's confession and leaves, telling him that she doesn't know who he is.
The next morning, Fusco is brought out to Oyster Bay where he buried Stills as his body is dug up. Soriano gloats that there is nobody that cares about Fusco while Simmons gloats about Fusco going down for Stills' murder. To everyone's surprise, Stills' body is not there, having been moved the night before by Carter with the help of Bear. Soriano insists that he will catch Fusco for Stills' murder, but Fusco just tells Soriano that he was wrong and asks for his badge and gun back. After Elias gets Azarello to recant his confession, Fusco is fully cleared and returns to duty. Carter asks him to look over a lead she has in Beecher's murder while she goes home. Fusco reads over the file, not noticing that Carter has Bear or that they are both covered in mud. (“In Extremis”)
Later, Fusco aids Sameen Shaw in taking out some gangsters who were after a POI that Shaw is dealing with. After Carter is demoted to patrol officer, Fusco also gets a clumsy new partner about whom he expresses his dislike to Carter. The two detectives have reconciled since Fusco's investigation by the IAB (“In Extremis”), and still occasionally help each other. (“Liberty”)
Upon Carter's request, Fusco attempts to access Beecher's NYPD file. He and Carter are both shocked and confused to discover that the file is restricted, and Fusco figures that someone has tampered with it as there are many HR moles still remaining in the NYPD. (“Nothing to Hide”)
Fusco also plays smaller roles in helping Reese and Finch on other cases, including assistance in watching Carter while she is presumably being stalked by a POI (“Lady Killer”), reviewing information on a lawyer and POI while watching her interrogation about a crime she was framed for (“Reasonable Doubt”), giving Reese information he was able to find on the whereabouts of Root and a kidnapped Shaw (“Mors Praematura”), and assisting Carter in faking the death of a sports memorabilia owner targeted by HR. (“The Perfect Mark”)
Fusco gives Reese some information on the Russians and their involvement in HR during an investigation of an intercepted drug delivery. He also later talks with Carter and insists that she could use some help in bringing down HR. Carter falsely accepts, and ditches Fusco while he goes to get his weapons from his apartment. (“Endgame”)
Fusco later assists Reese in watching HR's patrol of a federal department, since HR wants Reese dead. When Simmons sees bloodstains on an ambulance that Reese is hiding in, he sends his men after the ambulance, and Reese forcefully drives it away. Fusco shoots down two HR cops, but is discovered and knocked out by Simmons.
Simmons, Officer Lin, and Detective William Petersen keep Fusco in a fortune cookie factory and brutally interrogate him on the location of files Carter had of HR members. Simmons breaks Fusco's fingers, and later threatens to kill his son Lee if Fusco does not cooperate. Fusco finally gives in and tells them a location, which Simmons checks out. When Simmons finds out that Fusco lied, he sends Lin to go kill Lee and tells Petersen to kill Fusco. When Fusco profusely begs Petersen to have HR spare Lee, Petersen allows Fusco to call Lee to say his last goodbyes. Fusco promises Lee that everything will be all right, then hears a gunshot and begins to cry, but Shaw is the one that comes in on the other end, saying that Lee is safe. However, she says that she doesn't have enough time to save Fusco, and tells him she figured that he would've wanted her to save Lee.
Petersen then aims his gun at Fusco's head, but Fusco, who has been working at his handcuffs, frees himself and brutally strangles Petersen to death.
Later, Fusco is very grateful to Shaw for saving Lee. In his car, he watches Lee happily go to play hockey with some men (one of them presumably being Lee's coach and/or Fusco's friend(s)). (“The Crossing”)
After Carter's death at the hands of Simmons (“The Crossing”), Fusco and many other NYPD officers attend her funeral. Fusco then aids Finch and Shaw in finding Reese as he begins to lose control within his grief, using ruthless tactics to find Simmons. Reese finally finds HR's leader Alonzo Quinn, and prepares to kill him once he gets Simmons' location. Finch, Shaw, and Fusco arrive in time to convince him to stop, and Reese collapses from his prior injuries from Simmons during Carter's death. Finch and Shaw take Reese to a hospital while Fusco stays behind to make sure the FBI re-arrests Quinn.
While no one is looking, Fusco secretly picks up the piece of paper on which Quinn wrote down Simmons' escape route.
Simmons, who has purchased a fake Canadian passport to escape New York, arrives at an empty airport. Fusco, who has already told the pilot that Simmons would be missing his flight, confronts Simmons. The two engage in a brutal fistfight, and Fusco eventually wins by breaking Simmons' arm. Fusco then goes on to emotionally explain to Simmons how Carter saved his life by making him a better person. Fusco then arrests Simmons instead of killing him like he would have years ago.
Fusco later brings Simmons into the NYPD precinct in front of all the other people inside, who stare on in amazement. (“The Devil's Share”)
In the aftermath of the war with HR, Reese, who has become so unstable and upset at Carter's death that he has decided to leave the team, heads to Colorado. Finch sends Fusco to find Reese, which he does at a bar. Fusco sees that Reese has begun to drink and advises against it, pointing out that drinking was one of his own bad habits that he quit because of Reese. Reese says that all the work he's done with the team seems pointless now, and Fusco is appalled at how Reese could say such a thing. He challenges Reese to a fight, and the two engage in a fistfight out in the rain. However, the police arrive and find the two. (“Lethe”)
In a police cell, Reese tells Fusco that it was stupid of the detective to pick a fight with him, going on to say that he is lucky to still be alive. Fusco ignores the comment and says that the sheriff is keeping the two locked up for now. After Fusco convinces Reese to help Finch, they save Shaw and Finch when they are held at gunpoint by Vigilance. (“Aletheia”)
When Team Machine has to help Kelli Lin steal the Gutenberg Bible in order to entrap Cyril and rescue her daughter Kai, Fusco provides critical help in carrying off the heist by - providing security plans for Symmetric Security (where the Bible is stored), running distraction on Agent Bouchard, getting legitimate prints by tricking a Symmetric Security guard named Farrow, and running extraction for Reese after Reese gets himself captured as part of the plan. He then provides extraction for Shaw in the aftermath of the apprehension of Cyril by NYPD, when Shaw has to shoot Cyril before he can shoot Kelli.
He later joins the Team for a celebratory drink at Finch's safe house that night. (“Provenance”)
Ever since Fusco has arrested Simmons, his prestige at the precinct house has increased, leading to many detectives asking him for help. This initially irritates him, till Finch reminds him that this respect is what he has been working towards all the while ever since he decided to become a good cop. Once this starts sinking in, Fusco goes over to help Detective Jake Harrison, albeit a bit grudgingly, when the body of Tara Cooke is fished out of the river.
He and Jake go over to the workplace of Tara, a private equity firm. When they're checking if the carpet fibers found on Tara's body match the carpet there, her coworker Brent Holm wonders as to why they're checking the office when Tara's been killed at the river. Gina Kincaid and her husband Ron, the CEO and CFO of the company, meanwhile assure the detectives of their help. Fusco, in return, asks for security footage from Tara's last day at the office before she was murdered.
In the midst of all this, he's also been helping Team Machine with their person of interest, Sandra Nicholson, by checking to see if she has a criminal record, confirming the location of the Templarios gang hangout to Reese and then helps Finch analyze 911 calls. When he finds a call where Tara had called 911 and got Sandra, complaining about her boyfriend hurting her, that's when the Team's person of interest case and the Tara Cooke murder case tie up. He checks the map location and realizes that the call came from the same location where Tara died.
He and Jake then go back to Tara's office to confront Gina and Ron with footage from office showing Tara carrying the burner phone which she used to make the 911 call, a "delete voicemail" message (from phone records) that Tara left to Ron, saying that she wasn't going to help him cheat on Gina anymore, and exact match between the carpet fibers on Tara's body and Ron's trunk. After Gina admits that she and Ron hired someone to delete the 911 call made by Tara, leading to the current person of interest situation, Fusco and Jake arrest them.
After he and Jake return to the station, Jake thanks Fusco for his help. Fusco congratulates him back on his handling of the case, and then asks him to return to work. (“Last Call”)
Fusco then helps Team Machine protect Cyrus Wells from Decima Technologies, by keeping Cyrus safe at the precinct for a while, and then by engaging Decima men in a firefight when he and Reese have to rescue Cyrus after Decima kidnaps him.
He then escorts Root to the airport to help her catch a flight to Paraguay. (“Root Path (/)”)
When the next number is of Maria Martinez, Fusco and Shaw perform surveillance on her, and later they defend Maria from the French Legion hitmen who are after her. He then interrogates Ken Davis, CEO of the company Maria works in.
Later, when Team Machine attack the UN building to rescue Maria, posing as firemen, Fusco elects to drive the fire truck, pointing out that he always wanted to do that. He then assists the rest of the team fight of the French Legion hitmen, and takes down the key conspirator, Sevon, himself.
Fusco then delivers Omar Risha's paperwork for asylum at a restaurant with an open and attractive view of the New York skyline, where he's sitting with Maria. He then trades light banter with Shaw, buying her a champagne and wishing her a Happy Persian New Year, calling her "Sameen". (“Allegiance”)
While helping Finch investigate Leona Wainwright's murder by Vigilance, Fusco gets taken hostage by Collier, forcing Finch to give up key documents, relating to Northern Lights, to Collier. Fusco is then saved by Root. However, Collier uses those documents to force the government to shut down Northern Lights. (“Most Likely To...”)
When Greer gets Grace's details from Samaritan, during his effort to track down Finch, Fusco plays a key role in trying to protect her. He takes her to the NYPD Precinct, fends off the Decima operative posing as a FBI Special Agent and helps Root take down the security cameras inside the precinct, thus preventing Samaritan from watching.
Later when Greer's men release Grace in exchange for Finch, he's present at the exchange, driving her away to safety, and escorting her to the airport, where she goes on to her new job in Italy, based on new credentials created by Finch and passed on to her by Reese. (“Beta”)
Fusco is out on the streets during crowd-control, during the total blackout created by Vigilance, when he meets Reese and Hersh. When they talk about the trial orchestrated by Vigilance, Fusco has no idea what they are talking about.
Later when Samaritan goes fully operational, and one of Decima's operatives shoots down a Vigilance member to tie up strings, with the escorting cop as a collateral casualty, Fusco is one of the first to arrive at the scene. (“Deus Ex Machina”)
Season 5From the begining of Season 5, Fusco seems to drift further apart from Team Machine, being the only main character not aware of the Machine's existence. He begins an investigation into the suspicious rise missing persons, that unknown to Fusco, Samaritan has arranged. This leads to Samaritan labeling him as a "possible obstructionist". (“ShotSeeker”). Later on, he finds the missing bodies, including the body of Bruce Moran, dead inside of a tunnel system. The tunnel system is rigged with explosives and Fusco ends up in the hopsital. (“A More Perfect Union”) (“QSO”) After the explosion, Fusco severs ties with Team Machine, and files for a new partner at the NYPD.
While waiting for his new partner, Fusco is given the case of Amir Salik, a cab driver who was carrying a gun used in a murder Fusco investigated two years before. While Amir puts up an innocent act, Fusco ties him to murders in several other states and Amir drops the act. Reese later asks for Fusco's help while he rescues Terry Easton's wife, but Fusco refuses due to Reese's secrets. After the power goes out, Fusco finds Reese and Easton and the Templario gang free. Reese and Fusco subdue two Templarios and question Amir who reveals that he kills those who the Voice uses for his purposes. Amir offers them the Voice's true identity in exchange for a deal, but is nearly killed by a cop blackmailed by the Voice. The Templarios attack the outnumbered Reese and Fusco, leading to a shootout in which most of the Templarios are killed and the two cops run out of ammunition. As Reese goes for a Templario gun, Finch warns him that Terry Easton really is the Voice. Fusco jumps in the path of a bullet for Reese, getting grazed on the shoulder while the Voice uses the distraction of a final Templario gang member to escape. Afterwards, Fusco is patched up and Reese takes him up to the roof where he finally tells Fusco about the Machine, deciding to fully trust him. Now knowing the truth, Fusco joins the reunited Team beneath the Queensbro Bridge, becoming its newest member. (“Sotto Voce”)
Fusco attends Root's funeral and expresses sorrow at her death and the fact that she couldn't be buried under her real name. After the Machine gives them the relevant number of the President of the United States, Fusco joins Shaw and Reese in saving the President and is able to get them the list of every known threat to the President from a contact of his. As Shaw and Reese plan to attend a fundraiser the President will be at, Fusco is annoyed he's not invited and questions Shaw on her state of mind, something she blows off. As Reese and Shaw attend the gala, Fusco monitors them from their hotel room, continuing to express concern about Shaw's state. After Reese and Shaw stop a bomb, Fusco warns them that the threat against the President has been broadcast all over the news. When Reese tells him that Logan Pierce was at the gala and could've done the hacking, Fusco tells him that Pierce was all over the news for refusing to share data with the NSA. However, Pierce escapes from Reese.
The next day, Reese assigns Fusco to keep an eye on the President while he and Shaw interrogate Charles Vaida. Fusco later switches with Reese and he and Shaw follow Vaida to a house in DuPont circle. Shaw enters in alone, worrying Fusco who follows her. Fusco arrives just as a blackout occurs, allowing the two to take down the terrorists before both realize they didn't cause the blackout. Shaw figures out where the assassination is going to take place and leaves it to stop it herself, unsure of who to trust in the Secret Service while Fusco remains behind with the captured terrorists.
As Reese and Shaw attempt to stop things on site, Fusco monitors the situation through the terrorists surveillance feeds and questions Tracey on where the assassination will come from. While Tracey refuses to answer, Fusco notices her glance at the drone feed and realizes the attack will come from the drone monitoring the President and warns Reese and Shaw. Fusco tracks the drone's progress and reports on it to his friends. After the drone destroys the Presidential SUV, Fusco is able to confirm that the attack failed and the President survived. Before he can leave, a Secret Service agent warned by an anonymous tip arrives. Fusco is able to get the agent, who confirms he's a real police officer, to listen, but is questioned on why an NYPD detective is running an off-the-books operation in Washington, DC. Harper Rose shows up and is able to cover for and extract a surprised Fusco. Harper then takes Fusco to meet with Reese, Logan Pierce and Joey Durban who reveal that they also work for the Machine and had been protecting them. Fusco realizes that Pierce was the one who cut the power, letting him rescue Shaw. After the three head off after another number of their own, Reese tells Fusco they have to go back after Finch again and face "one hell of a fight." (“Synecdoche”)
After returning to the precinct, Fusco is surprised to find that the bodies from the tunnel have been discovered and is interrogated and then kidnapped by Agent LeRoux who is a Samaritan operative and the killer. LeRoux takes Fusco to the beach and shoots him twice, but Fusco is wearing a bulletproof vest and overpowers LeRoux, wondering whether or not to kill him as he would've done in the past. (“.exe”) Fusco later confirms to Reese that he killed LeRoux and stuffed him in a trunk, stating he hasn't changed that much. (“return 0”)
After the uploading of the ICE-9 virus at Fort Meade, Fusco returns with Reese to the 8th precinct to use their resources to find Finch. Fusco is reluctant and they are brought into their lieutenant's office where he reveals that he knows Reese is "the Man in the Suit." Reese knocks the lieutenant out, but they are captured outside the office by ESU officers and they are taken to the pier for their execution by three police officers bribed by Samaritan. The two are rescued by Finch and a sniper hired by the Machine before they can be killed however.
After the assassination attempt, Fusco is taken to the Subway where he is finally introduced to the Machine properly. Fusco comments he thinks they are all nuts but agrees to stay and protect the Machine with Shaw while Reese and Finch destroy Samaritan's backups. Following the Machine's instructions, Fusco blows the entrance to the subway tunnel and they flee on the Machine's train car. Along the way, Jeffrey Blackwell attacks them but Fusco is able to capture him. After arriving at the next stop, Blackwell cuts himself free and stabs Fusco twice in the side, seriously wounding him before running off. Shaw helps Fusco outside where they witness a cruise missile fired by Samaritan on its way to kill Reese.
A week after Samaritan is destroyed, Fusco recovers from his injuries and takes care of Bear. He meets with Shaw in a café, telling her he doesn't know if Reese or Finch survived or not. Fusco tells her he is back to work and gives Shaw Bear before the two say goodbye and Shaw departs. (“return 0”)
