History Recap / PersonOfInterestS03E21

* ShownTheirWork[=/=]DoingItForTheArt[=/=]FridgeBrilliance: During his interrogation of Grace, Greer reveals that Grace is from South Carolina. As Grace gets more stressed and upset, a touch of a [[UsefulNotes/AmericanAccents Southeast regional accent]] creeps into her voice.

'''Greer''': ''[soft chuckle]'' [[CrowningMomentOfFunny The espresso machine is on its way]]. And let me assure you, Senator, Samaritan is running as smooth as a Swiss watch.

* PetTheDog: Despite having had her kidnapped, Greer is unfailingly polite to Grace, doesn't reveal to her that he's hunting Finch, and lets her continue to believe Finch is dead.

** [[http://disney.wikia.com/wiki/Ellsworth Ellsworth]] is {{Goofy}}'s mischievous pet crow.

* FromBeyondTheFourthWall: As Shaw and Reese rescue Grace at first, the usual [[IdiosyncraticWipes Idiosyncratic Wipe]] gets [[InterfaceScrew subverted hard]]: Samaritan instead crops the screen to the heroes and provides it to Greer and Virgil. You can almost ''feel'' the fourth wall crumble down.

* GenreSavvy: Greer ''immediately'' realizes that Team Machine has figured out where they are once his men report that the car they were trailing was being used as a distraction to lead all of Decima's mooks to the other side of the city. He has his tech disassemble everything so they can move to a new location.

* AnalogyBackfire: Michaelangelo painted standing up.

* WorthyOpponent: Finch is Greer's, almost to the point of obsession.

* AsideGlance: Root winks at the camera in the police precinct that she knows is being monitored by Samaritan and Decima.

** Shaw shoots someone about to kill Root, who complains that she holed the notebook (with crucial information on it) he was carrying.
-->'''Root:''' "You couldn't have aimed two inches lower?"

* DangerouslyGenreSavvy: Greer. He immediately recognizes one of Team Machine's distractions as a sign that they know where he is and are heading straight for him. He also recognizes from Grace's passionate defense of her fiance that Finch will give himself up in exchange for her.

* SinisterSurveillance: For the first time literally true. Unlike The Machine, Samaritan's main objective is killing the main characters.
* SpikingTheCamera: Root winks at the camera in the police precinct that she knows is being monitored by Samaritan and Decima.

* FreezeFrameBonus[=/=]ShoutOut: The name on Grace's new passport is "Grace Ellsworth," which is a subtle reference to Finch's ThemeNaming.
** "Ellsworth" is the name of [[WesternAnimation/Goofy Goofy's]] pet crow.

->''"Just remember what our Machine sees, Samaritan sees. Two gods playing with the same deck of cards.”''

* CallBack: [[http://imgur.com/a/4z0ol A subtle one.]] The place where Greer has Harold taken to is the empty IFT office where he built the Machine.

* CarFu: A Decima SUV rams Team Machine, enabling them to kidnap Grace.

** Shaw shoots someone about to kill Root, who complains that she holed the notebook (with crucial information on it) he was carrying. "Couldn't you have aimed two inches lower?"
* TheComputerIsYourFriend / DeusEstMachina: The Machine, yes. It even has "protecting assets" as part of the protection protocol. [[{{Understatement}} Samaritan, no.]]
* CrazyPrepared: Finch, as ever. The Machine, for example, uses "Protection Protocol 7" at the start.
* DangerouslyGenreSavvy: Greer. He immediately recognizes one of Team Machine's distractions as a sign that they know where he is and are heading straight for him. He also recognises from Grace's passionate defense of her fiance that Finch will give himself up in exchange for her.
* DespairEventHorizon: Finch, after Grace is taken, is so distraught that he willingly surrenders himself to Greer to ensure her safety.
** Not to mention when Finch surrenders himself to Decima, he tells Reese and Shaw to refrain from violence at all costs. He then goes on to instruct them to murder all of Decima's men if they harm Grace in any way.

* HonorBeforeReason: Reese insists on answering a ringing phone, knowing he will be caught on camera.

* IHaveYourWife: Grace and Finch were never actually married, but Greer makes effective use of her as a hostage nevertheless.
* ImpersonatingAnOfficer: Reese's habit of introducing himself as Detective Stills backfires when Grace finds a Missing poster of the real Stills.

* InterfaceScrew: This episode is from Samaritan's perspective, rather than the Machine's.

* LeaveNoWitnesses: Decima poison the crew of the ship bringing the servers to be used for Samaritan into the United States. [[NiceJobFixingItVillain This only gives Root the opportunity to steal the servers herself.]]
* LonelyFuneral: Grace is bewildered that her fiance had no friends willing to turn up for his memorial.

* MacGyvering: Root makes an induction coil out of duct tape, copper wire, needle-nosed pliers and an extension cord.
* NeverFoundTheBody: Finch after the ferry bombing.

* PrisonerExchange: Averted; Reese offers to swop Greer's tech guy for Grace. The tech guy then kills himself using Reese's pistol.

* SinisterSurveillance: For the first time literally true, unlike The Machine, Samaritan's main objective is killing the main characters.
* SpikingTheCamera: Root winks at the camera in the police precinct that she knows is being monitored by Samaritan/Decima.
* TheSpook: Finch, almost comically so. Samaritan doesn't even have a picture. It, of course, helps that the Machine is actively protecting him itself.

* TakeItToTheBridge: Jefferson Bridge is used for the exchange, because it's too exposed for any treachery, especially with all the cameras accessed by the Machine and Samaritan.

* {{Unperson}}: The Machine attempts to make Finch disappear even more than he already has from the public view. It works, too... but Greer finds another way.
* WeNeedADistraction: Cue StuffBlowingUp. Unfortunately it's not enough. Giving your car to a wino works better.

* NoBodyLeftBehind: Finch after the ferry bombing.

** Not to mention when [[spoiler:Finch surrenders himself to Decima]], he tells Reese and Shaw to refrain from violence at all costs. [[spoiler:He then goes on to instruct them to murder all of Decima's men if they harm Grace in any way.]]

-->'''- Root'''

->''"From the day the Machine went online, part of me knew that I would never be able to sever myself from it and that anyone I ever cared about was in danger. It was foolish to imagine otherwise. I tried to guard myself, stay hidden, from the government, the authorities, people looking. Here we still are. This moment was inevitable. This moment was always looking for me."''
-->'''- Finch'''

* TakeItToTheBridge: Jefferson Bridge is used for the exchange, and is covered by cameras monitored by both AI's.
