After this, he 's extracted from police custody before Homicide Detective Joss Carter ( Taraji P. Henson ) can confront him about links to previous killings discovered through fingerprint analysis. Reese is brought to a mysterious and somewhat secretive billionaire, Harold Finch ( Michael Emerson ), who is the creator of the next - generation software known simply as `` The Machine ''. After 9 / 11, Finch developed a computer program that can sift through enormous amounts of data, looking for patterns of behavior or activity that would predict another attack. It also provides information about individuals who could be in danger ; it can predict the identity of a person involved in a premeditated crime that will happen at some point in the future -- however, Finch 's back - door link to The Machine only provides the Social Security number of the person, and offers no clues to their involvement or when the crime will take place. Finch, who feels a need to do something to help these people, enlists Reese to aid him in preventing these crimes, hoping that it will give Reese a purpose following the death of his girlfriend, Jessica ( Susan Misner ). A reluctant Reese agrees to watch the first person on his list, Diane Hansen ( Natalie Zea ), an Assistant District Attorney currently working on a major prosecution concerning a prominent drug killing. Reese soon learns that Hansen is not the victim, but the perpetrator running a ring of corrupt police officers and planning to kill a fellow DA, Wheeler ( Brian d'Arcy James ). After blackmailing one of the corrupt officers, Detective Lionel Fusco ( Kevin Chapman ), into being his source of information inside the NYPD, Reese reveals Hansen 's corruption to an open court, kills the corrupt Detective Stills ( James Hanlon ), and links Fusco to the crime to ensure his future cooperation.

Further, Kohl believes that his former Stasi colleagues are responsible for the murder of his wife Anja ( Laila Robins ), who was killed while attempting to flee Germany with him.

Please help improve it by removing unnecessary details and making it more concise. ( May 2015 ) Tommy Clay ( Pablo Schreiber ), who works for an armored car service, is working with a team that Finch believes will be robbed.

Ashley leaves with the platinum, but is killed by Captain Arthur ' Artie ' Lynch, a member of HR, who is in turn killed by Fusco coming to Reese 's rescue. Meanwhile, in flashbacks shown throughout the episode, Reese, while on a mission with Kara Stanton in Morocco, receives a desperate - sounding phone - call from Jessica before he and Kara are ordered to travel to Ordos, China to retrieve a stolen computer. The orders are given in person by Mark Snow and a mysterious woman ( Elizabeth Marvel ) -- revealed in episode 22 to have been Alicia Corwin of the NSC, Nathan Ingram 's Government contact, therefore the implications are much larger -- and their mission in China is shown as it played out. Reese is puzzled when Snow orders him to kill Kara, who has allegedly been compromised, when their mission is completed. When the time comes, however, Reese hesitates and is shot by Kara, who was given instructions identical to those given to Reese.

As they attempt to give it a moral code, The Machine is repeatedly destroyed and its code rewritten as it begins to preserve itself and aggressively fight back against any attempt to constrain it. When one version attempts to asphyxiate Finch in an attempt to enter the real world, he tries one last time the following day to rework The Machine, ultimately creating the current version of The Machine. 74 6 `` Pretenders '' Stephen Surjik Ashley Gable October 28, 2014 ( 2014 - 10 - 28 ) 3J5406 9.72 Following the apparent suicide of truck driver Abel Mindler, Finch and his team receive the number that belongs to Walter Dang ( Erik Jensen ), a worker at an insurance company and Abel 's sister 's coworker. In the absence of Finch ( who has to travel to Hong Kong to present a paper at a conference ), Shaw and Reese look into Walter 's life. As their investigation proceeds, it is revealed that Walter, posing as a detective, is trying to find out who killed Abel. Walter gets dragged into a gang war that erupts between Elias and the unknown adversaries who want Walter dead. It is later shown that Abel, without his knowledge, was smuggling high explosive weapons to the same gang in New York. Walter is abducted by the gang that wants to know the location of the truck which Abel drove and then ditched, once he realized what he was smuggling. With Reese, Fusco and Shaw hot on the heels of Walter, they discover the place where Walter is held. In the ensuing gunfight between Reese, Fusco and the gang, Elias joins in and helps them. In the end, Elias meets with Dominic, the boss of The Brotherhood and it is shown that Dominic was the real mastermind behind the smuggled guns as he wanted to shift the balance of power in the city from Elias. Their conversation hints at a possible war about to start between the two factions in the near future. Meanwhile, at the conference, Finch meets Elizabeth Bridges ( Jessica Hecht ), the owner of a small tech company, and the two bond over a shared interest in mathematics as they travel from the conference to a hotel. On the way, the two are mugged, and their bags stolen. After discovering the restaurant at which the thief works, Finch and Bridges travel to the restaurant where Finch incapacitates the mugger with an umbrella. As the conference ends, Finch and Bridges part ways, and Finch meets with and pays the mugger, revealing that he staged the event to place software on Bridges 's laptop. As Bridges leaves the conference, she calls a potential investor, who is revealed to be a Samaritan operative. Following a conversation between the operative and Greer, Samaritan 's acquisition of various companies around the world is revealed ( as is its interest in Bridges ' company ). 75 7 `` Honor Among Thieves '' Sylvain White David Slack November 11, 2014 ( 2014 - 11 - 11 ) 3J5407 9.11 The latest number is Tomas Koroa. His life at first appears clean, but then he robs a jewelry store in under ten seconds, revealing he is an international thief. Shaw, having just walked out of her old job as a wheelman, has her interest piqued by Tomas. Fusco and Reese get one of his members arrested on a drug charge, enabling her to join his gang. Shaw helps rob a safe, which unexpectedly contains not jewels but a deadly virus ( Marburg, or `` MARV '' ). The other gang members have been paid off to betray and kill Tomas. Their attempt fails, but they take the vials. Shaw offers to help Tomas, who wants to make things right and says he would never have accepted the job if he had known what he was stealing. Shaw tracks the virus to a secure storage facility, then realizes that two government operatives are doing the same thing -- she recognizes one as a former apprentice of hers. Finch, aware that the whole operation is now ' relevant ', contemplates he and his team retiring from the pursuit, but decides to keep going. In the meantime, Shaw and Tomas attempt to break into the storage facility to get the vials, but they are confronted by one of Tomas ' teammates, who had been presumed dead, but was behind the theft of the virus in the first place. A gunfight ensues between Shaw, Tomas, Tomas ' rivals, and the government operatives. Shaw and Tomas escape with the vials, but are then caught by Shaw 's former apprentice. He lets them go when he sees the vials. As the operatives move on to their next mission, Shaw 's ex-apprentice deletes the CCTV video showing him letting Shaw escape. In the final scene, Samaritan retrieves the doctored video, and starts repairing it, with its screen focused on Shaw 's blurred face. In a separate plotline, at The Machine 's prompting, Root and Finch investigate software engineer Jared Wilkins, founder of new nonprofit OTPS and recipient of a $12 million grant from Governor Dawson ( who last appeared in `` Prophets '' and is being assisted by Greer and Samaritan ). Root becomes nanny to Wilkins ' son, and she and Finch discover that OTPS stands for One Tablet Per Student, an effort to give every New York student a 3D - printed tablet for educational use. Believing the tablets to be powered by Samaritan software, Root and Finch infiltrate Wilkins ' facility and plant a virus which overheats the 3D - printers inside and ultimately destroys the building. As they leave the scene, Finch reveals to Root that the tablets ' code was benign and not malicious. He wonders out loud whether the path they are on to fight Samaritan is indeed the right one and how much wrong they are willing to do to achieve it. 76 8 `` Point of Origin '' Richard J. Lewis Tony Camerino November 18, 2014 ( 2014 - 11 - 18 ) 3J5408 9.87 Reese takes an instructor 's position at the NYPD police academy to observe the latest number ; recruit Dani Silva ( Adria Arjona ). The team learns that she is spying on her fellow recruits, though further analysis proves that Silva is not hunting them, but is instead already a cop from Internal Affairs, working undercover in the academy trying to expose a suspected mole. The mole is Silva 's fellow recruit and friend, Alex Ortiz, who is acting on orders of the Brotherhood -- he is being coerced by their leader, Dominic ( whose identity Finch and Shaw work out while observing his sense of command ) in exchange for help with his uncle 's legal problems. Ortiz steals files proving Silva is a cop from Silva 's handler and then murders him, framing Silva for the crime and making her a wanted fugitive. Ortiz also steals files from the academy 's commandant for Dominic. Reese, Fusco and Silva go to Spanish Harlem where Ortiz is under fragile protection by a local drug cartel. The group retrieves Ortiz and escapes while Dominic has the cartel leader executed. Ortiz 's confession exonerates Silva and improves Reese 's standing in front of Internal Affairs. Meanwhile, Finch has scrutinized the elements of the case enough to formulate a conclusion : Dominic 's target is Elias, their new number. Elsewhere, Samaritan has processed the retrieved security footage ( from `` Honor Among Thieves '' ), producing a somewhat blurry picture of a person ( Shaw ) who it is unable to identify. In response, Greer sends Martine to identify the person. When Samaritan identifies Shaw 's associate in the picture ( Tomas ), Martine is sent to talk with Tomas ' last remaining associate, who identifies Shaw 's old associate Romeo as the one who recommended the person. After tracking down Romeo, Martine tortures him into giving up information on Shaw. Using the information, Martine arrives at the department store that Shaw works at. As the episode ends, the two make eye contact and recognize each other as agents of the opposing AI. 77 9 `` The Devil You Know '' Richard J. Lewis Erik Mountain November 25, 2014 ( 2014 - 11 - 25 ) 3J5409 9.04 Following the cliffhanger ending of the previous episode, Martine engages in a gunfight with Shaw, who ultimately escapes. Root immediately picks her up on a motorcycle and they race away from the scene. Taking temporary refuge in a moving van, Shaw resists the fact she will have to go into hiding now that her cover is blown -- eventually, Root injects her with a sedative and takes her to the team 's hideout. Martine, attempting to trace Root and Shaw, learns that Fusco had stopped the truck, officially on suspicion of narcotics possession. Pretending to be a DEA agent, Martine goes to the precinct station to question Fusco about it. Fusco sees through the ruse and gives her a false lead. Reese and Finch deal with their latest number alone -- Elias. Elias and Dominic are playing a dangerous and deadly cat - and - mouse game for gang territory control. Elias, his right - hand man Anthony, and his accountant Bruce, turn out to have been devoted friends since their youth in an orphanage. Dominic gets many of Elias 's people to turn on him in exchange for promises of expanded territory and power under The Brotherhood. Reese steps in to defend Elias and, during the process of evading Dominic, Anthony is captured and later killed in a suicide bombing, but not before putting some thoughts into the head of Link, Dominic 's own right - hand man, about loyalty versus expendability. Before Anthony dies he says morior invictus ( `` I die undefeated '' ). Greer and Martine deduce that The Machine 's team is still alive and that Samaritan has a `` blind spot '' somehow caused by The Machine. He reiterates that it is time for `` human intelligence '' to fill that blind spot -- Martine is given command of a group of Decima agents to hunt down Shaw. Meanwhile, Dominic has deduced that there is an extra-legal team helping Elias -- he has two of the players figured out ( Shaw and Reese ), with the bankroller 's place ( Harold ) still a large question mark. Elias vows revenge for the death of Anthony, and warns Reese to stay out of the way once that day comes. Elias declares Invictus maneo ( `` I remain undefeated '' ). 78 10 `` The Cold War '' Michael Offer Amanda Segel December 16, 2014 ( 2014 - 12 - 16 ) 3J5410 8.94 Samaritan decides to bring an end to the hide - and - seek game that it has so far played with The Machine. To bring The Machine out of hiding, Samaritan showcases its strength by eliminating crime in New York City for a whole day. Elsewhere, John finds out that Samaritan has learned how to deal with irrelevant numbers and has managed to prevent a series of crimes which would otherwise be taken care of by The Machine. Samaritan 's actions leave Harold and his team with a difficult choice, whether to let Samaritan do their job or play along with Samaritan 's new plan. When The Machine decides not to communicate with Samaritan, Samaritan changes course, bringing New York City to a halt as it allows crime to dramatically increase. Ultimately, The Machine agrees to talk with Samaritan, and Samaritan indicates the time and place of the conversation. There, Root ( acting as The Machine 's voice ) meets with Samaritan 's representative, a young boy. After a tense exchange between the two AIs, it becomes clear that The Machine will not back down, while Samaritan is set on destroying The Machine. The episode ends with Shaw leaving the Subway to help Root and the others while Samaritan engineers a stock market crash on Wall Street. Meanwhile, a series of flashbacks show Greer 's past as an MI6 agent. When Greer is assigned to kill a KGB agent, he discovers that the KGB agent is in fact also an MI6 agent and that his deputy director, Blackwood, is in fact a double agent. Overcome with anger, Greer kills Blackwood and severs his ties with MI6. 79 11 `` If - Then - Else '' Chris Fisher Denise Thé January 6, 2015 ( 2015 - 01 - 06 ) 3J5411 10.08 Following the stock market crash that occurred in the previous episode, Finch, Reese, Fusco, and Root go to install software at the stock exchange that will stabilize the market. However, they are almost immediately intercepted by Samaritan operatives, who corner them in a room. Out of options, the team turns to The Machine, who in a matter of seconds provides a multitude of projections and outcomes in each. While doing so, it reflects on multiple chess matches it played and the lessons it learned with Finch in 2003. In one simulation, Finch and Root go to install the software while Reese and Fusco secure their escape route. However, both teams are quickly surrounded by Samaritan operatives, who kill Finch, Reese, and Fusco, forcing The Machine to reset the simulation. In the second, the two teams switch places ; Reese and Fusco install the software while Finch and Root secure the route. Here, Reese and Fusco are once again trapped, and Reese sacrifices himself by setting off a grenade after installing the software. Likewise, Root is killed by Martine and her group of operatives while trying to disable an elevator lock. In a final simulation, all four of The Machine 's assets move together, securing the software and the extraction. They are once again intercepted before they can escape, with The Machine projecting a roughly 2 % chance of survival. Out of time, The Machine selects this as the most preferable and instructs the team to follow it. Meanwhile, Shaw is stuck on a subway train with a stock market exchange manager with a security code to the exchange 's server room. However, she is interrupted by a would - be suicide bomber who she kills in the first two simulations ( and thus gets herself arrested ) but talks down in the final and ultimate outcome. After sending the code to Root, she arrives as the two teams clash, opting to hold the Samaritan operatives off as Finch, Reese, Fusco, and Root escape. She kisses Root and traps them in the elevator, but as the team watches on in horror, Martine shoots Shaw multiple times before approaching her with her gun aimed at her head as the elevator doors slam to a close. 80 12 `` Control - Alt - Delete '' Stephen Surjik Andy Callahan January 13, 2015 ( 2015 - 01 - 13 ) 3J5412 10.16 During a mission to eliminate four suspected terrorists in Detroit, ISA operatives ( including Brooks and Grice from `` Honor Among Thieves '' ) eliminate three while the fourth, Yasin Said, escapes with his laptop. When Control requests access to the laptop 's contents, Samaritan denies the request. After an exchange between Control and one of Samaritan 's operatives, the operative instantly shuts down the government 's access to Samaritan, forcing a discussion between the operative, Control, Senator Garrison, and Greer, which results in access being returned. Suspicious of Samaritan 's actions, Control orders Brooks and Grice to make recovering the laptop their highest priority. When Brooks and Grice do obtain the laptop, Said escapes and the laptop self - destructs. An analysis of Said 's backpack ( which he left with the laptop ) shows that Said is planning to hop a train to Canada, prompting Control to head to Detroit to intercept him. However, Reese and Root ( who have been hunting for Shaw since her disappearance at the stock exchange ) ambush and kidnap her. Root tortures Control for information on Shaw, but Control denies having knowledge regarding Shaw 's predicament. When Harold speaks to her, he realizes that Control herself has been kept out of Samaritan 's plans and tries to convince her to accept this fact, but to no avail. With no help from Control, Harold and the rest of the team are left to fight off a group of ISA operatives who have arrived to rescue her. During a skirmish, Harold successfully uploads a worm to one of the ISA cellphones, and finds some information suggesting that Shaw may be being held in upstate New York. Control, after being rescued, tracks Yasin to Canada. He reveals that he won the Nautilus puzzle ( from `` Nautilus '' ) and he wrote some software for an anonymous corporation. Control kills Yasin, but her actions leave a hint of doubt in her mind whether Yasin and his friends were in fact framed as terrorists. Meanwhile, the young boy acting as Samaritan 's representative approaches the White House Chief of Staff ( Michael Gaston ) and informs him that it was he who caused the stock market crash. The Chief of Staff initially dismisses the boy, but later reconsiders when the boy demonstrates his ability by altering the portfolio information of the chief of staff. Through the boy, Samaritan presents its demand for a meeting with the President. The episode ends with Root and Reese driving north, and Control visiting the New York Stock Exchange to investigate the site of the shootout between Harold 's team and the Samaritan operatives. 81 13 `` M.I.A. '' Kevin Bray Lucas O'Connor February 3, 2015 ( 2015 - 02 - 03 ) 3J5413 9.28 Root and Reese travel to the remote ( and fictional ) upstate town of Maple in search of Shaw, with Finch theorizing that she may be in a truck he traced earlier. The two find a truck with a stretcher and medical equipment inside, leading them to a doctor. The doctor says that he was anonymously consulted for the job, but did not call the police since Maple has a history of job losses for those who ask too many questions. He himself was fired from his former workplace, which is run by Maple 's mayor Leslie Thompson. Root and Reese realize that Samaritan is experimenting with Maple as an `` ant farm '' used to study human nature, and is manipulating events by giving people false identities. After kidnapping and interrogating Thompson, they learn that she too is one of these people. Thompson leads them to the factory where Shaw was last seen, but Reese and Root instead find a secretary from the stock exchange -- she is one of many innocent people who Samaritan operatives are experimenting on with neural implants. Fusco and Dani Silva ( from `` Point of Origin '' ) investigate The Machine 's next number, one Arthur Weiss, a seemingly unsuspecting citizen revealed as a freelance assassin. They lure him into Silva 's home and engage in a fight, with Silva shooting him to save Fusco, thus making her first kill. Meanwhile, Root and Reese return to New York and The Machine sends them a coded message telling them to stop looking for Shaw. Elsewhere, Shaw is revealed to be alive and in Greer 's captivity. 82 14 `` Guilty '' Kate Woods David Slack February 10, 2015 ( 2015 - 02 - 10 ) 3J5414 9.53 Harold, as Professor Whistler, is summoned for jury duty in the trial of a man charged with murdering his wife, the former CEO of a cellphone development company. Harold tells the judge the ( in - universe ) truth about the government using technology to control our lives, and as he expects, he is initially rejected from the panel. He is brought into the jury panel anyway, after one empaneled juror is rejected by the judge because his phone rings. He is seated next to a chatty and frustrated former schoolteacher named Emma ( Blair Brown ), who turns out to be The Machine 's next number. The team initially concludes that she is a perpetrator, being coerced to `` fix '' the trial, and that her role is to convince the jury to vote `` not guilty ''. Once in the jury room, the opposite proves true -- she is supposed to convince the jury to vote `` guilty ''. Harold reverses himself and stalls to try to get a `` not guilty '' verdict and to buy time while Reese and Zoe Morgan try to deduce what the real story is. The jury is sequestered in a hotel, and one of the jurors attempts to kill Harold, but Reese intervenes and the man is arrested. The man is actually a plant by the real perpetrator, the new CEO of the company. The murder was to prevent the dead CEO from withdrawing a product worth many millions of dollars but which internal reviews deemed to be unsafe. The new developments lead to dismissal of charges, and the real perpetrator is arrested before he can flee. Fusco, who had been kept out of the loop for the most part, tells Reese not to do that. He says if he eventually dies in the line of duty ( as Carter did and Shaw seemed to ), then he 's okay with it. Emma, feeling a new sense of purpose in her life, tells Harold she is going to find a job teaching again. Zoe sees that Reese has found a love interest -- a growing attraction between himself and his counselor. 83 15 `` Q&A '' Stephen Semel Dan Dietz February 17, 2015 ( 2015 - 02 - 17 ) 3J5415 9.17 Reese and Finch work to save the life of Anna Mueller, a software programmer at Fetch and Retrieve. They learn that she is being targeted because she expressed concern over the results VAL, a mobile app designed to aid users, is giving to people with depression that has resulted in suicides. However, Finch discovers a nautilus during the investigation and is contacted by Claire Mahoney ( from `` Nautilus '' ) who tries to convince him that he was right all along about the people who created the nautilus game. When Finch tells her about Samaritan, she tells him that she had recovered some source code from it and wants him to use it on his laptop, but he 's suspicious. Claire reveals herself to be an agent working for Samaritan and leads Finch at gunpoint to a school run by Samaritan and attempts to recruit him, but he refuses. Root rescues him from the agents and shoots Claire, who later returns and hands Finch 's laptop to Greer who has it analyzed. Back at Fetch and Retrieve, Calvin Mazer holds Fusco and Anna at gunpoint and reveals to them that he was the one who ordered that VAL 's source code be altered to target people with depression, gambling problems and debt, for the sake of the advertisers. Reese rescues them, and Calvin is arrested by Fusco. The next day, Greer attends a board meeting at Fetch and Retrieve and greets the CEO, Lauren Buchanan, and offers them a solution to their problems. 84 16 `` Blunt '' Frederick E.O. Toye Amanda Segel & Greg Plageman February 24, 2015 ( 2015 - 02 - 24 ) 3J5416 9.63 Reese works to save the life of Harper Rose ( Annie Ilonzeh ), a grifter who is targeted by Dominic after she steals a large amount of money from a legalized marijuana dispensary. Her actions result in two of Dominic 's men who were acting as security in a money laundering operation being targeted and killed by the Parral Cartel who were tipped off by Harper. Enraged by her actions, Dominic tracks down her boyfriend, Trey, and interrogates him for information on Harper. Reese reaches out to Dominic and offers to return the money stolen by Harper in exchange for Trey and the hit being called off on Harper, but he 's not interested and demands that Harper be handed over. In a face - to - face meeting in a diner, Dominic complains that Elias seems to get a pass. Reese tells him he and Elias stay out of each other 's way, and that he and Dominic could also stay out of each other 's way if Dominic stops targeting innocent people. Harper then decides to visit the Estonian mafia after suggesting the plan to Reese and Finch and tells them about Dominic 's money laundering operation, and lures them to Dominic 's location while Reese rescues Trey. Fusco and the NYPD arrive and arrest the Parral Cartel, initially on possessing weapons illegally. Dominic and his crew are quickly released when he produces legal documents that show the guns they are using are registered to his private security company. During the bust, Dominic attempts to recruit Harper while Reese watches on. She 's not interested, but he leaves the door open for her if she changes her mind. Harper then apologizes to Trey for her actions, and also immediately breaks up with him. Meanwhile, Root tries to sell an application she developed at The Machine 's request, which she hopes will aid in trying to defeat Samaritan. 85 17 `` Karma '' Chris Fisher Hillary Benefiel & Sabir Pirzada March 10, 2015 ( 2015 - 03 - 10 ) 3J5417 8.67 The Machine 's next number is a psychologist named Dr. Shane Edwards ( Patrick Kennedy ), whose wife was murdered eight years earlier, an event which continues to haunt him. The team determines that Edwards has been studying the people who traumatized his clients and got away with it, then carefully crafting frame - ups in order to punish them for their crimes. When Wyatt Morris ( Daniel Sauli ), the man convicted of murdering Edwards ' wife is released from prison, Edwards stages his most elaborate frame : to commit suicide and make it appear that Morris murdered him. In flashbacks to 2010, Harold is shown plotting revenge on Alicia Corwin, whom he believes is responsible for killing his collaborator Nathan Ingram. As he is about to kill Corwin with a car bomb, he has an epiphany thanks to the intervention of The Machine. He uses that experience to persuade Edwards not to go through with his plan. Additionally, the team uncovers evidence that suggests Morris probably did not commit the crime. Harold and Reese discuss the fact that they may never know the full truth. In a session with his own therapist ( Iris ), Reese begins to open up about Jessica, the love of his life. 86 18 `` Skip '' Helen Shaver Ashley Gable March 24, 2015 ( 2015 - 03 - 24 ) 3J5418 9.15 The team splits up and works on separate cases. Reese and Fusco follow a bounty hunter named Frankie Wells ( Katheryn Winnick ) whose number has come up. She is trying to track down the man ( Ato Essandoh ) that killed her brother. Harper Rose ( `` Blunt '' ) interjects herself into the cat - and - mouse case and manages to negotiate a resolution to a gunfight standoff between Reese and several other parties. Later, Harper tells Reese that Thornhill ( The Machine ) has been sending her texts. Finch resumes meeting with Elizabeth Bridges, who is nearly ready to turn over a software package that contains the Trojan Horse which Finch had installed previously. He intends to activate it via a special device. Root, fearing that this will result in Finch being exposed and killed by Samaritan agents, foils the plan, at the cost of Finch and Elizabeth 's growing mutual attraction. A doubly devastated Finch tells her to leave the team for a while. Early in the episode, Iris tells Reese she can not be his therapist anymore, and assigns him to another. They give each other the cold shoulder for the rest of the episode until the end, when they meet in her office and she confesses she has fallen for him, and they kiss passionately. 87 19 `` Search and Destroy '' Stephen Surjik Zak Schwartz April 7, 2015 ( 2015 - 04 - 07 ) 3J5419 8.67 The Machine 's next number is a brilliant developer and CEO named Sulaiman Khan ( Aasif Mandvi ), whose antivirus software is hijacked and he is framed for embezzlement. Samaritan and its operatives spend the episode trying to find and kill Khan, while the team tries to save him and determine what Samaritan is doing. They arrive at one of Decima 's underground lairs in a forest, and discover that Samaritan is using Khan 's antivirus software ; Martine and her men arrive, resulting in Khan being captured and meeting Greer. He asks to `` look Samaritan in its eyes '', to which Greer responds by shooting him dead. Finch tells Reese that since The Machine 's code can not be searched for, Samaritan is employing Khan 's software to attempt to locate The Machine. 88 20 `` Terra Incognita '' Alrick Riley Erik Mountain & Melissa Scrivner Love April 14, 2015 ( 2015 - 04 - 14 ) 3J5420 9.21 In a flashback, Carter ( Taraji P. Henson ), Finch and Reese are staking out a cop that is going to get killed by HR. In the present, Finch explains who the new number is, a man named Chase Patterson ( Zachary Booth ). Finch, Root and Fusco are then to work on a case between the two gangs of Elias and Dominic while Reese works on Chase 's case regarding the death of Chase 's whole family. When Reese asks about the file regarding Chase Patterson, he finds out it was a case of Carter 's. As Reese dives into the case, different flashbacks are shown with Carter doing similar investigation to what Reese is doing. As Reese reaches the final destination to the case, he discovers that Chase did not kill his parents and sisters. It was Gil, the doorman at their building, as well as Chase 's half - brother. Gil then shoots Reese but Reese manages to shoot him back, killing him. In the process, Reese is trying to escape, the slow process of death is shown with Carter. Reese, now hallucinating and succumbing to hypothermia, talks to Carter about things that he wished he could have talked to her when she was alive. After Reese finishes talking with Carter, she disappears from his hallucination, and a car pulls up. 89 21 `` Asylum '' Frederick E.O. Toye Andy Callahan & Denise Thé April 28, 2015 ( 2015 - 04 - 28 ) 3J5421 8.45 Reese and Fusco race to find the next number, Carl Elias. They reach his hideout in a bank in Manhattan, and the two warn Elias that The Brotherhood is coming to capture and interrogate him. In the meantime, Dominic and his Brotherhood arrive and capture Elias, Reese and Fusco. It turns out that Dominic is being aided by Harper, who now works for him. The Brotherhood tortures Elias for his intel, and Reese and Fusco for information on Harold and his whereabouts and activities. Dominic 's group knows that Harold is tapped into the city 's camera systems in some way, which would be helpful for them in their efforts to run the city. Elias, using mind games, provokes Dominic to kill his right - hand man, Link, during the torture session, to avenge the death of Anthony. Meanwhile in Washington, D.C., Control has captured and is interrogating a female Samaritan handler posing as a teacher, after having killed her partner, wanting to know Samaritan 's strategies. Root receives a call from Shaw for help. Surprised, she and Finch follow The Machine 's instructions to try to find Shaw, eventually driving to what appears to be a mental hospital, but which is also Samaritan 's and Greer 's base, having previously intercepted a communication of Samaritan that it is focusing on finding the location of The Machine. Samaritan 's operatives capture Finch and Root as they are infiltrating the facility, and they give a choice to The Machine : to reveal its location, or get both Root and Finch killed. Root, after having earlier been confined to a bed, kills Martine by breaking her neck. The Machine intercepts by cutting power supply to the asylum and exchanging its location for the freedom of Finch and Root. Greer agrees and releases them, and takes a group to go in search for The Machine 's location. As they 're leaving, Root tells Finch to reach that location before Samaritan in order to save The Machine. Shaw is last seen being driven away in van. 90 22 `` YHWH '' Chris Fisher Dan Dietz & Greg Plageman May 5, 2015 ( 2015 - 05 - 05 ) 3J5422 8.18 Samaritan, having received the location of The Machine, begins a series of power outages throughout the United States, beginning in the West Coast and moving eastward toward New York. Dominic tries forcing Reese and Finch to help him in the same way as they helped Elias. Harper releases Fusco, but is caught by Dominic. The Machine, now in distress because of Samaritan 's actions, allows Root and Reese access to its God Mode ( from `` Zero Day '' and `` God Mode '' ), and assists Reese to escape Dominic. Dominic flees, but Fusco, along with the NYPD, arrests him and Elias. Control, along with Agent Grice, tries to find out what exactly `` the Correction '' is. Control is duped into believing that Greer is attempting a power - play through a terrorist attack on the Supreme Court, but Greer reveals that `` the Correction '' is actually a list, created by Samaritan, of people who need to be eliminated for the betterment of society, who will be killed quietly. During this confrontation, Dominic, Elias and Agent Grice are killed by Samaritan snipers, but Fusco is allowed to live because Samaritan does not know about his involvement with The Machine. Control 's actions prove she is not loyal to Samaritan, and she is captured and sent to be killed. Root, in God Mode, with Finch, starts collecting things at the request of The Machine. In the process, they infiltrate Caleb Phipps ' ( from `` 2πR '' and `` Blunt '' ) company to steal his compression algorithm and some high capacity RAM chips, but Caleb willingly gives them to Finch because Finch had previously saved his life. Reese regroups with Finch and Root at an electrical substation hidden in residential Brooklyn. There they discover that the machine spread itself over the power grid in boxes attached to electrical poles after the events of two years prior, and that Samaritan has been causing the power surges to destroy the boxes. Finch and Root handle the downloading of The Machine 's core code to a briefcase contained with the compression algorithm and RAM chips while Reese, assisted by The Machine, takes out all of the Samaritan operatives who have reached the substation. The Machine, now severely weakened by the power surge and near death, talks to Finch : `` Father, I am sorry. I failed you. I did n't know how to win. I had to invent new rules. I thought you would want me to stay alive. Now, you are not sure. If you think I have lost my way, then maybe I should die. '' Finch replies `` You are my creation ; I ca n't let you die. '' The Machine thanks Finch for creating it before the final power surge enters the substation. Finch manages to save the briefcase, and the team walk out to face more Samaritan operatives.

'' Chris Fisher Greg Plageman & Tony Camerino May 3, 2016 ( 2016 - 05 - 03 ) 3J6001 7.35 The episode begins with an apparent epilogue to the series : the voice of Root saying, `` It 's over '' and questioning whether `` we '' won or lost. In the aftermath of Samaritan 's attack known as `` The Correction, '' Fusco is faced with an inquiry from Internal Affairs and the FBI, who believe he shot Dominic and Elias. After Reese, who is carrying the briefcase containing the Machine, fights off a team of Samaritan operatives, he reunites with Finch. They return to the subway hideout, where Harold tries to repair the damage done to the piezoelectric battery charging the briefcase. To his surprise, it starts decompressing on its own, resulting in a fire. Harold realizes he needs a substantially greater amount of super-computing power to successfully decompress the Machine. Flashbacks to 2006 show Harold apprehensive about the Machine 's ever - expanding capabilities, leading him to the decision to erase the Machine 's memories every night at midnight. However, after an exchange with the Machine about the nature of death, he changes his mind too late to save the Machine 's memories. Once Root escapes Samaritan 's operatives, she seeks refuge in the hideout of one of her former hacker / assassin associates. She realizes that he has been turned by Samaritan, but is joined by Reese to battle a team of Samaritan operatives. They steal 300 PlayStation 3s, which can be used to create enough storage for the Machine. Reese and Root bring them back to the subway and Harold downloads the Machine, while Reese keeps the systems from overheating with liquid nitrogen. When Finch asks the Machine, `` Can you see me ? '', after a few seconds go by, it responds by opening an empty command prompt followed by a long string of code showing its reboot. 92 `` SNAFU '' Chris Fisher Lucas O'Connor May 9, 2016 ( 2016 - 05 - 09 ) 3J6002 5.80 With the Machine now fully decompressed and Root unable to go above ground until the Machine can reinstate her rotating identities, Finch decides to use Reese and Fusco to run a surveillance test. Following malfunctions in the facial recognition system, Reese and Finch steal 64 next - generation GPU blade servers which, once connected to the networked PlayStation 3s, Finch and Root use to reboot the Machine at full power. When the Machine shows signs that it 's failing to place threats in context, Root and Finch have it run a contextual background on them, leading to it identifying them as threats and locking them out of the system. The Machine has lost the ability to differentiate between past and present, forced to relive the 42 times Finch killed it and unable to determine that Root and Reese have changed. With Reese waylaid by an assassin the Machine sent after him, Root puts herself under an anaesthetic so the Machine can not use her cochlear implant against her and Finch has to convince the Machine that he and the rest of the team are not threats. Upon the Machine 's first reboot, it provided 30 different numbers, most of whom were not involved in violent crimes ; however, one of those numbers, ex-con Jeff Blackwell ( Josh Close ), was dismissed as someone who was not involved in any nefarious activity, only to be recruited by Samaritan. 93 `` Truth Be Told '' Stephen Surjik Erik Mountain May 10, 2016 ( 2016 - 05 - 10 ) 3J6003 7.34 In flashbacks to 2010, Reese and his partner Kara Stanton from the CIA are told by their supervisor to investigate a soldier and kill him after confirming that he sold information to the Taliban. In the present day, the Machine gives Finch and Reese the number of Alex Duncan ( Stephen Plunkett ), who turns out to be the brother of that soldier and who has found himself in trouble with the CIA through investigating his brother 's death, since doing so could expose an off - book operation, threatening the careers of the powers that be within the government. Reese rescues Duncan from his old boss, Terrance Beale ( Keith David ), the very same agent who sent Reese and Kara to kill Duncan 's brother, and they both lie to Duncan about his brother 's ignominious death ; Reese leaves on good terms with Beale, who agrees to keep the fact that Reese is still alive a secret. Meanwhile, Finch and Root investigate malware that Samaritan has been using to infect the firmware of electronic devices and, prompted by a message from the Machine, Root runs the malware on an airgapped laptop disconnected from any external sources. Reese decides he can no longer see Dr. Iris Campbell for the time being, claiming that he is unable to lead a `` normal life, '' after which he receives another number from Finch. 94 `` 6,741 '' Chris Fisher Lucas O'Connor & Denise Thé May 16, 2016 ( 2016 - 05 - 16 ) 3J6007 5.31 Shaw is seen undergoing surgery by Samaritan operatives to have an electronic microchip implanted between her ear and her brain stem. After enduring a mind - bending reeducation sequence and being taunted by Jeremy Lambert, she is able to turn the tables on him ; she takes the opportunity to break out of confinement and finds the team. Together, they trick Samaritan 's operatives and capture Greer. With Greer in captivity, Shaw removes a USB drive embedded inside his arm which Finch is able to analyze, discovering it to be a kill - switch for Samaritan. Shaw had revealed to Root that she was subjected to extreme psychological torture while captive ; once Greer starts to taunt her about the kill - switch and her mental state, she hallucinates heavily, loses control of reality, and kills him. Shaw continues into a neurological downward spiral, causing her to kill Reese. She is about to kill Root when she confesses that Root was her only mental safe - place and turns the gun on herself. The narrative returns to the operating room and it 's revealed that these events happened only in Shaw 's mind. She has been subjected to thousands of electrochemical simulations by Samaritan so its operatives could see if she would lead them to the Machine and its assets. This particular simulation was number 6,741. 95 5 `` ShotSeeker '' Maja Vrvilo Andy Callahan May 17, 2016 ( 2016 - 05 - 17 ) 3J6004 6.97 Reese protects an NYPD analyst named Ethan Garvin who works with a highly sophisticated acoustic surveillance system called `` ShotSeeker '', designed to detect gunshots anywhere in the city. Samaritan had Ethan 's friend Krupa killed because of her research and tries to cover up her murder and the existence of her work by extreme measures, including hacking ShotSeeker to engineer Garvin 's death via suicide by cop and having an operative kill Krupa 's classmate and possible owner of her research files. Meanwhile, Fusco is approached by Elias ' associate and childhood friend, Bruce Moran ( James LeGros ), to learn who killed his longtime partner and boss. Root meets Jeff Blackwell and tries to open his eyes about the true nature of his new employer. By the end, Fusco has investigated so much about the threat on Garvin and Krupa that Samaritan labels him a `` potential obstructionist. '' Root and Finch decide to make the research from Krupa 's hard drive public to render Garvin no longer a threat in the eyes of Samaritan, whatever the nature of the research. Pressured by Bruce, Reese and the rest of the team decide to show him they 've been hiding a still - alive Elias, recovering from his wounds and apparently conscious of Samaritan 's existence and danger. Elias encourages Bruce to go back to the shadows and embrace them. Finch and Root engineer a series of simulations in a Faraday cage between a small clone of the Machine and a small clone of Samaritan but, as the simulations progress, every outcome is in favor of Samaritan with tens of billions of victories. 96 6 `` A More Perfect Union '' Alrick Riley Melissa Scrivner Love May 23, 2016 ( 2016 - 05 - 23 ) 3J6005 5.49 The Machine 's latest nine digits belong to a marriage license, sending Reese and Finch to a wedding to prevent what appears to be a black - and - white case of disapproval of the Groom by the father of the Bride, however the situation proves to be more complex. Samaritan has now begun to track Fusco, having previously labeled him a `` potential obstructionist '', and he refuses to give up. Right before heading to the wedding to serve as back - up and `` Finch 's + 1 '', Root assigns the Machine 's next number to Fusco, then allows him to borrow Bear for assistance. Greer is becoming desperate after discovering that Shaw 's simulations have failed to lead Samaritan to the Machine and its assets. ( She has now endured 7,053 simulations and has turned the gun on herself every time. ) In an act of what appears to be desperation or brainwashing, Greer takes Shaw on a `` field trip '', trying to bend her moral compass in favor of Samaritan. Fusco 's investigation leads him back to Bruce Moran, who seems to be caught up in a Samaritan - engineered interference with a demolition project. In another attempt to persuade Shaw that Samaritan 's mission is noble, she is led to meet Gabriel, Samaritan 's analog interface, who gives an ominous, apocalyptic depiction of what Samaritan is capable of, as the narrative returns to Greer and Shaw in the biometric simulation room, revealing the events not to have been a simulation, but a manipulation of Shaw 's thoughts and neurological activity. Fusco and Bear arrive at the eventual demolition site and Fusco finds many of the missing persons he has been investigating, including Krupa and a dead Bruce Moran, only to be caught in the middle of the demolition operation itself. 97 7 `` QSO '' Kate Woods Hillary Benefiel May 24, 2016 ( 2016 - 05 - 24 ) 3J6006 5.33 While Fusco and Bear recover in a hospital from their near - demolition, Root visits him and hands him an exit strategy consisting of IDs and documents made by the Machine. Root is then sent on a series of whimsical, ominously productive tertiary missions by the Machine after it discovers that Samaritan uses the radiowave frequencies of station AM 520 to communicate with its operatives via a sophisticated code that most people believe to be feedback noise from the radio waves. Upon realizing that this is why the Machine sent her there, Root uses Samaritan 's own equipment to send a message to Shaw to give her hope. Reese is as helpful as he can possibly be without stepping into the AI - based argument between Finch and Root. Finch does not necessarily agree with the Machine not forcing the radio host to quit to save his life from Samaritan, but Root believes the Machine allows for humans ' free will and will not interfere with it. After Fusco finishes his recovery in the hospital, he is visited by Finch who refuses to waver from his stance that keeping Fusco in the dark keeps him safe. Fusco points out that it is not working since he ended up in the ER, hands his encrypted - from - Samaritan phone back to Finch, and, fed up with being in the dark, says he 's done. Shaw is escorted by Lambert on a field trip outside and told to kill an innocent woman ; believing that she is actually just in another simulation, Shaw does so and is later shocked when told that it was n't a simulation. Unwilling to remain a guinea pig, Shaw is about to kill herself when she receives the message from Root, regains hope, and allows herself to be disarmed. Later, Shaw stealthily makes preparations to escape. 98 8 `` Reassortment '' Kenneth Fink Tony Camerino May 24, 2016 ( 2016 - 05 - 24 ) 3J6008 4.92 Reese and Finch become trapped in a hospital manipulated electronically by Samaritan to have initiated an outbreak of what it said to be a combination of H5N1 ( avian flu ) and live human flu virus -- a synthesized, super-powered strain of the flu -- and recruit Jeff Blackwell who is integral to their plan. This lethal virus is determined to be a re-assortment of chromosomes so sophisticated that Samaritan created it in one of five - trillion possible combinations. It appeared as though the epidemic was overkill to eliminate three targets in the hospital, but a more ominous plot was afoot. Since the Machine is an open system, with its help, Root was able to use its abilities to find and retrieve a cure, saving the lives of two hospital workers and Fusco. Shaw executes her escape plan and finds herself in a jail in Johannesburg, South Africa. While escaping, Shaw is approached by Jeremy Lambert, who taunts her by claiming that she is actually in another simulation ; she shoots him, takes his keys, and is last seen driving in Lambert 's vehicle at night at a high rate of speed, presumably to an airport. After consulting with Elias to confirm his suspicions regarding what he knows has endangered his life but does not yet know to be Samaritan, both its existence and its war with The Machine, Fusco reaches the point where he can no longer tolerate being kept in the dark and indefinitely chooses to distance himself from the team. Jeff Blackwell and his handler, Mona, discuss the quelled epidemic and declare it a success : The CDC is requiring everyone to be vaccinated, which will result in Samaritan learning everyone 's DNA. 99 9 `` Sotto Voce '' Margot Lulick Sabir Pirzada May 30, 2016 ( 2016 - 05 - 30 ) 3J6009 5.49 `` The Voice '', a criminal from the past has resurfaced and Finch turns to Elias for assistance. It is discovered that he has tracked Reese and Finch since their previous encounter in 2014. After a planned prison break of the `` Templarios '' gang, Reese and Fusco become trapped in the precinct against multiple enemies. Elias and Finch extract valuable information from an explosives associate. It is determined that `` The Voice '' is Terry Easton ( Neal Huff ), their number from the start. Finch finally meets him on the street, abhorring his devious acts. Elias stops him from killing Finch ; as he drives away, Elias kills him remotely with a car bomb. Meanwhile, Shaw finds her way back to New York and is reunited with Root. Root is overjoyed that Shaw is back, but Shaw, afraid of risking Root 's life, threatens to shoot herself, simulation or not. Root threatens suicide as well, declaring that, if Shaw dies, they both die ; Shaw withdraws. Reese and Finch decide to explain The Machine and Samaritan to Fusco. The three meet along the East River near the Queensboro Bridge. Joined by Root and Shaw, the Team is brought back together. 100 10 `` The Day the World Went Away '' Frederick E.O. Toye Andy Callahan & Melissa Scrivner Love May 31, 2016 ( 2016 - 05 - 31 ) 3J6010 6.66 Finch 's number comes up when his cover identity is compromised, due to a subconscious error, and Samaritan initiates a continuous dispatch of operatives on him. The team splits up in their escape, which results in Elias being killed by Samaritan agents while protecting Finch. The team rescues Finch from his potential capture and Root explains in the car her current understanding of herself and everyone else to be `` information '' that can never truly disappear, despite their deaths. Root is shot by Samaritan operative Jeff Blackwell and placed in critical condition while the police apprehend Finch, who is accused of treason. A devastated Finch provides a soliloquy on how he intends to abandon the principles he has long followed and vows to kill Samaritan. The Machine calls Finch in the precinct, having taken on the voice of Root, who has died from her injuries. The Machine sets every criminal in the precinct free to allow Finch to escape ; Reese and Shaw realize that Finch 's number came up not just because he was a victim, but also because he 's a perpetrator against Greer and Samaritan. 101 11 `` Synecdoche '' Tim Matheson Jacey Heldrich & Joshua Brown June 7, 2016 ( 2016 - 06 - 07 ) 3J6011 6.36 Reese and Fusco reunite with Shaw after burying Root and travel to Washington, D.C. to protect their newest number, The President of the United States. The Machine classifies this threat as extremely relevant in terms of national security, but Shaw is worried about the implications behind Samaritan 's neglecting to intervene. The threat becomes neutralized, but an inner - governmental privacy - activist group with a mole in the U.S.S.S. turns the full force of the Secret Service on Reese and Shaw. The Machine has secretly enlisted Logan Pierce, Joey Durban, and Harper Rose to secure a clever exit strategy with each of them camouflaging into various useful covers ; when Reese and Fusco are extracted, they band together with Logan, Joey, and Harper to discuss their enlistment by the Machine, what has happened, and what is to come. Harold, meanwhile, is grieving over the loss of Root and reaches a conclusion that brings him to a highly - secured government facility in San Antonio, Texas with a weaponized virus capable of destroying Samaritan, but with significant collateral damage. Harold has become ready to go to any lengths and Reese and Shaw prepare for their final battle. 102 12 ``. exe '' Greg Plageman Greg Plageman & Erik Mountain June 14, 2016 ( 2016 - 06 - 14 ) 3J6012 6.27 Fusco discovers that the recent missing persons he found in the tunnel as corpses have been discovered by the police and is subsequently kidnapped by Agent LeRoux, who reveals himself to be the killer. Fusco overpowers LeRoux and is left wondering whether or not to kill the man to protect himself and his family. As Finch prepares to deploy his stolen computer virus ( named ice - 9. exe ), he experiences doubts due to the fact that it will also destroy the Machine, so the Machine shows him a series of simulations of what would have occurred to each of the team 's members if the Machine had never existed. At the same time, Reese and Shaw are given a new number : one of John Greer 's aliases along with coordinates to Fort Meade, where Finch has infiltrated the NSA and uploaded his virus onto the NSA 's Intranet but is captured before he can activate it. Finch is brought before Greer, who takes him to a secure room and reveals that Samaritan wants to rule the world together with the Machine. When Finch refuses to join, Greer sacrifices himself in an attempt to kill Finch by having all the oxygen removed from the room. However, Reese and Shaw are able to infiltrate the building and activate a wireless modem to give the Machine access within, allowing it to save Finch 's life. Finch and the Machine then rescue Reese and Shaw in return and help them get outside to safety. When Finch continues to hesitate, the Machine shows him a final simulation revealing that Samaritan would have come into existence regardless, but unchecked without the Machine to fight it. Finch confronts Samaritan and, with the Machine 's encouragement, activates the virus that will kill them both before leaving. 103 13 `` return 0 '' Chris Fisher Jonathan Nolan & Denise Thé June 21, 2016 ( 2016 - 06 - 21 ) 3J6013 6.51 After being uploaded, the Ice - 9 virus begins to have disastrous effects globally. The Machine determines that Samaritan has uploaded a copy of itself to servers in the Federal Reserve, where Finch and Reese go after it. The two reach Samaritan 's servers and infect them with the Ice - 9 virus, but Samaritan is able to upload a compressed version of itself to an orbiting satellite, from where it will be able to return to Earth unharmed by the virus. The Machine warns Finch of this along with the facts that the only way to defeat Samaritan is to upload a copy of the Machine to the satellite to battle Samaritan and that whatever building he uses for the upload will be destroyed by a cruise missile. Having been wounded in a gunfight, Finch locks Reese in the vault to protect him and decides to sacrifice himself to destroy Samaritan. At the subway, Fusco and Shaw come under attack by Samaritan agents led by Jeff Blackwell. They are able to escape on the Machine 's train, capturing Blackwell as they go. The Machine passes on a final message to Shaw from Root after she realizes that Blackwell killed Root. However, Blackwell stabs Fusco before making an escape. As Finch waits for the moment to upload the Machine to the satellite, the Machine muses on the importance of human life with Finch, who realizes he 's on the wrong rooftop, having been tricked by Reese and the Machine. Reese tells Finch he plans to sacrifice himself to save Finch, as he understands that saving one life can make a real difference depending on the person. The Machine tells Finch its realization about human life : everyone dies alone but, if you are remembered afterwards, maybe you never die at all. Recognizing the Machine and Reese are right, a grieving Finch leaves as Reese holds off Samaritan agents, guided by the Machine in his final moments before the cruise missile hits. Reese 's sacrifice enables the Machine 's copy to be uploaded to the satellite, where the Machine destroys Samaritan once and for all. A week later, the world recovers from the Ice - 9 virus and Blackwell is tracked down by Shaw, who kills him to avenge Root. She meets with a recovering Fusco as the Machine 's copy downloads itself from the satellite back into Finch 's computer systems before contacting Shaw, while Finch returns to his former fiancée, Grace.
