History Recap / PersonOfInterestS04E19

** ShownTheirWork: His cigar of choice is the ultra-expensive [[http://www.gurkhacigars.com/home.php Gurkha.]]

* DownerEnding: 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. The Samaritan screen then triumphantly lights up with a "threat eliminated" message.

* GoodSmokingEvilSmoking: This time, it's evil all the way with Greer breaking out a cigar after shooting Mr Khan
* HeroesWantRedheads: Zoe says that she thought John would avert this, and was surprised
[[Recap/PersonOfInterestS04E18 with him and Iris beginning a relationship]].

** Having increasingly switched over to using a Glock 17 as his primary sidearm, Reese offers Harold his SIG-Sauer {{P226R}} , his main weapon of choice for the previous three seasons.

** Khan's company [[ChekhovsGun was targeted by]] [[Recap/PersonOfInterestS04E11 the flash crash]].

* {{Expy}}: Khan's software seems to be one for McAfee Antvirus. Arguably, Khan himself may be one for John McAfee but a little less... eccentric.

* TheBusCameBack: [[Recap/PersonOfInterestS04E14 Zoe Morgan]] is called to clean up the mess at Khan's company.

* VisualPun: Reese calls shotgun, [[DontExplainTheJoke while holding a shotgun]].

* EvilBlonde: Averted. Martine's dyed her her brown. Root lampshades this.

* PreMortemOneLiner: Perhaps the most blunt in the series.

* BoringButPractical: In a sense, Reese's M4 carbine. While not the most exotic weapon POI has featured, the scope and having switched the fire-selector to semi-automatic allows John to Curb-Stomp the Samaritan team with incredibly accurate single shots rather than wasting rounds with the usual suppression/ATeamFiring that Team Machine usually does. Notably, this is what any RealLife trained soldier would do, instead of wasting their magazine on fully automatic.

--> ''Greer'': Very Well.

* OnePhoneCall: Khan asks for this, but Samaritan makes it look like he's already gotten it.
* PistolWhipping: Root does it to Samaritan assets.

** Averted with, ironically enough, the Machine itself. Samaritan couldn't find the Machine on any networked device with Khan's software installed around the world. This debunks the popular fan theory that the Machine is running on regular people's personal devices and all but confirms that the servers "Thornhill" moved are still active.

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

* CigarChomper: Surprisingly enough it's [[spoiler: Greer, who after shooting the number of the week lights up to celebrate.]]

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

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

** During the episode flashback focusing on the end of his career at MI6, Greer utilized a Walther PPK. He breaks another out here to murder Khan.

** There is also a callback to the episode before this, [[Recap/PersonOfInterestS01E23 "Firewall"]], where Reese says "Just because you're paranoid, doesn't mean they're not trying to kill you." Funny enough, the person he said this to was Root.

** Reese's VisualPun is a reference to [[Recap/PersonOfInterestS02E22 when Shaw handed Reese a shotgun and says she's driving]].
