History Recap / PersonOfInterestS04E19

-->'''Finch:''' There's only one thing powerful enough to systematically destroy Khan's personal and professional life this throughly.
-->'''Khan:''' ''(being eavesdropped on)'' Well this is the crazy part. It's not human that's after me. It's an artificial intelligence.
-->'''Finch:''' [[HijackedByGanon Samaritan]].
-->'''Khan:''' It's here. We always knew this was possible. Consider what's happened to me!
-->'''Samaritan:''' [[AC:intercepting cell phone signal... target located. threat level: ''high'']] ''(draws a target symbol on Khan)''

-->'''Khan:''' What networks are covering this?
-->'''Assistant:''' All of them.

* YouKnowTooMuch: Khan is removed from control of his company because he stumbles across Samaritan's secret use of his software. When he deduces an AI is behind things, Samaritan decides to kill him.

** Samaritan can screw with traffic lights and activate street blockades.

* EvilBlonde: Averted. Martine's dyed her her brown. [[HypocriticalHumor Root lampshades this]] while [[PreMortemOneLiner throttling her]]:
-->"I liked you better as a blonde."

* CrashingThroughTheHarem: Root hides in a hotel room where two people are having sex.

** This isn't the first time [[Recap/PersonOfInterestS03E03 Root has used]] KnockoutGas [[Recap/PersonOfInterestS03E03 on a large number of people]]. She also says, "[[Recap/PersonOfInterestS03E03 You're the boss]]" to the Machine before smashing the Faberge egg.

** This isn't the first time [[Recap/PersonOfInterestS03E03 Root has used]] KnockoutGas [[Recap/PersonOfInterestS03E03 on a large number of people]].

** Samaritan's response to Khan's death.

* PremptiveDeclaration: Root tells the waiter to lie down. [[KnockoutGas He falls down instead]].

* CuttingTheKnot: The security on Khan's phone is too good for HollywoodHacking, so our heroes hack the phones of the people he's calling. When Reese want to hear what's happening in the board meeting, it turns out that Zoe Morgan has been invited. When faced with CCTV cameras, Reese just shoots them.

* IncrediblyObviousTail: Khan eyes Reese suspiciously in the bar, and recognises him after Reese springs him from prison. Naturally he assumes Reese is working for his enemies.

* TrackingDevice: There's one in the briefcase, and Root has to short it out using a lamp.

* ConvenientlyTimedAttackFromBehind: Reese knocks out a security guard who sees Khan drilling the lock on the generator room. Finch warns Reese about a Samaritan mook creeping up behind him, then moments later Reese saves Finch's life the same way.

* TheDeterminator: Khan, which eventually causes his death.

* HandcuffedBriefcase: Root cuffs the briefcase to her own wrist.

* PistolWhipping: Root does it to Samaritan assets, Reese to a security guard.

* BaitAndSwitch: Finch points out that it will only be a matter of time until Samaritan finds the Machine's location. The payphone rings ominously... and Samaritan switches scenes to where Greer tells Khan that their search found no trace of the Machine on any networked device in the world.

* GoodSmokingEvilSmoking: This time, it's evil all the way with Greer breaking out a cigar after shooting Khan

* ItsPersonal: Root and Martine for each other. They even discard their weapons.

* KnockoutGas: Root uses this in a restaurant.

* MinorCrimeRevealsMajorPlot

* PistolWhipping: Root does it to Samaritan assets.

* ProperlyParanoid: Khan. Justified since he runs a computer security company.

** ''Samaritan'' plays this straight. When Reese shoots the cameras, its first instinct is to send for maintenance.

Sulaiman Khan, the billionaire [[InsufferableGenius eccentric genius]] who founded the world's foremost computer security company, wakes up to learn that the company has been hacked. His private e-mails--including all the ones where he rips into his friends and co-workers--are being discussed on all the morning news shows, steamy pictures of his [[TrophyWife estranged wife]] are in the hands of the tabloids, the board of directors has just fired him after seeing financial records that make it look like he was embezzling from the company, and [[FromBadToWorse the IRS is raiding his condo]]. Khan is convinced that only an artificial intelligence could breach his company's security, and that the AI is [[ItsPersonal out to get him]]. He doesn't know [[ProperlyParanoid just how right he is]]: the hacker was Samaritan, which wants to use his antivirus software (and the "immunization chip" he's developing) for its own ends, and it ''is'' out to get him--which is why The Machine gave Finch Kahn's number.

* ContinuityError: Glaring one. Reese uses the Nemesis Arms Vanquish take-down sniper rifle to destroy some perimeter cameras. Once they get into the sever room, for the rest of the episode, it magically turns into a scoped M4 carbine.

* CurbStompBattle: Look closely in the climax and you'll see that it's not Team Machine that's on the defensive. Reese and Root carve through multiple Decima assets despite being outnumbered, and only withdraw due to losing the POI and running low on ammo.

* EverythingIsOnline: Samaritan can activate street blockades.

* {{Expy}}: Khan's software seems to be one for [=McAfee=] Antivirus. It comes pre-installed on nearly every computer, has a not-so-great track record as of late and has a founder who is no longer with the company. Arguably, Khan himself may be one for John [=McAfee=], the founder of McAfee, albeit a little less... eccentric than his real-life counterpart.
* FauxAffablyEvil: Up until this point, Greer's affable EvilBrit stchick was so well done, one could forget that he was even an antagonist. Here, he begins to drop the facade and display a LackOfEmpathy in the climax.

* HeroesWantRedheads: Zoe says that she thought John would avert this, and was surprised [[Recap/PersonOfInterestS04E18 he was beginning a relationship with Iris ]].

* ImprobableAimingSkills: Root lends a hand via God Mode and plays spotter for Reese when he utilizes a sniper rifle on some security cameras.

* ProperlyParanoid: Khan, justified since he runs a computer security company.

* TheBadGuyWins: The POI leaves the protection of Team Machine, gets apprehended by Samaritan and after a brief conversation is shot by Greer, who smugly lights up a cigar while standing over the man's corpse. Samaritan's interface, projected onto the wall, then [[VictoryPose triumphantly]] lights up with a "threat eliminated" message.

* IKnewIt: Khan says this when he is proven right about the existence of artificial intelligence.

** Later Reese lays down scarily accurate fire with an M4 carbine when engaging Samaritan assets.
* InsufferableGenius: Khan seems to have been this throughout his career, and it's the main reason why everyone, including his closest friend, turns on him so quickly after the hack

* AdvertisedExtra: Zoe is in all of two scenes.

* {{Expy}}: Khan's software seems to be one for [=McAfee=] Antivirus. It comes pre-installed on nearly every computer, has a not-so-great track record as of late and has a founder who is no longer with the company. Arguably, Khan himself may be one for John [=McAfee=], the founder of McAfee, albeit a little less... eccentric than his real-life counterpart.
