In the aftermath of Samaritan's attack known as "The Correction," Fusco is being questioned by Internal Affairs and the FBI, who believe he shot Dominic and Elias. Reese and Finch return to the subway hideout, where Harold tries to repair the damage done to the piezoelectric battery charging the briefcase containing The Machine. To his surprise, it starts decompressing on its own, resulting in a fire. Flashbacks to 2006 show Harold apprehensive about the Machine's ever-expanding capabilities, le

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, are used 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

In flashbacks to 2010, Reese and his partner Kara Stanton from the CIA are told to investigate a soldier and kill him after confirming that he sold information to the Taliban. In present day, The Machine gives 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. Reese rescues Duncan from his old boss, Terrance Bea

Shaw is seen undergoing surgery by Samaritan operatives to have an electronic microchip implanted between her ear and her brain stem. She is able to turn the tables on them by breaking out of confinement and finding 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 ext

Reese protects an NYPD analyst named Ethan Garvin who works with an 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 hacking ShotSeeker to engineer Garvin's death via suicide by cop and having Krupa's classmate and possible owner of her research files killed. Elias' associate and childhood friend, Bruce Moran (Jame

The latest number belong to a marriage license, sending Reese and Finch to a wedding to prevent what appears to be a typical case of disapproval of the Groom by the Bride's father, however the situation proves to be more complex. Samaritan has now begun to track Fusco, having previously labeled him a "potential obstructionist". Root assigns the Machine's next number to Fusco. In an act of desperation, Greer takes Shaw on a "field trip", trying to bend her moral compass in favor of Samaritan. Fus

Root visits a recovering Fusco and hands him an exit strategy for himself and his son consisting of IDs and documents made by the Machine. The Machine discovers that Samaritan uses the radio wave frequencies of station AM 520 to communicate with its operatives via a sophisticated code that most people believe to be feedback noise. Upon realizing the reason why the Machine sent her there, Root uses Samaritan's own equipment to send a message to Shaw to give her hope. Finch does not necessarily ag

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 send Jeff Blackwell at the hospital. It appeared as though the epidemic was overkill to eliminate three targets in the hospital. Since the Machine is an open system, Root was able to use its abilities to find and retrieve a cure, saving the lives of t

"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 meet

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

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. But Shaw is worried about the implications behind Samaritan's neglecting to intervene. The threat is identified as a domestic terrorist group who are against the President's surveillance programs. The attempted assassination is stopped with the unexpected assistance of former POIs Logan Pierce, Joey Durban, and Harper Rose who each camouflaged th

Fusco discovers that the missing persons he found in the tunnel as corpses have been discovered by the police and is kidnapped by Agent LeRoux, who reveals himself to be the killer. As Finch prepares to deploy his stolen computer virus (named ice-9.exe), he's hesitant because 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. Reese and Shaw are given a new number: one of Jo

The Ice-9 virus begins to have disastrous effects globally. Samaritan has uploaded a copy of itself to servers in the Federal Reserve. Reese and Finch infect Samaritan's servers there with the virus, but Samaritan uploads a compressed version of itself to a satellite. The Machine tells Finch that the only way to defeat Samaritan is to upload a copy of the Machine to the satellite and that whatever building he uses for the upload will be destroyed by a cruise missile. At the subway, Fusco and Sha
