History Characters / PersonOfInterestNorthernLights

* JerkWithAHeartOfGold: She's abrasive as hell and a borderline zealot when she goes to work, but she's genuinely motivated at protecting her country from security threats, and tries to do her job to the best of her ability.

* KillEmAll: Standard operating procedure in the event the existence of Research is compromised to the outside world. They're also willing to let terrorists attacks occur if necessary, if it means the source of the leak stands a good chance of dying in one.

* [[OnlySaneMan Only Sane Woman]]: She seems to be the only one in Northern Lights who finds Greer to be utterly untrustworthy.

* KillEmAll: To anyone who even suspects the Machine exists.

* KillEmAll: His general orders to anyone who might know about The Machine.

* [[KarmicDeath Karmic Torture]]: Root tortures him using a method that he authorized U.S. Intelligence officers to use on terrorists - and makes a point of showing him a copy of the document in which he did this during the proceedings.

* WeaponOfChoice: A SIG-Sauer [=P229R=]. She puts it to very good use in "Aletheia". She switches to a Smith and Wesson M&P Compact in Season 4, which she uses to murder an innocent man framed as an Islamist Extremist.

* WeaponOfChoice: The SIG-Sauer [=P229R=] for both of them, and the Nemesis Arms Vanquish take down sniper rifle for Brooks.

* TheDragon: To Special Counsel and Control, who both run him at different times.

* AffablyEvil: Offers Garrison a SpotOfTea when he comes to inquire about the status of Northern Lights' secrecy.

* DragonAscendant: [[BiggerBad Control]] orders him to kill Special Counsel, and he does so. He doesn't count as TheStarscream because he was JustFollowingOrders.

* BiggerBad: The one who is giving orders to Special Counsel, Hersh and their people.

* BigBad: Of Season 2. Control remains the BiggerBad, however.

* BadassBeard: Grice has a somewhat modest one.

illainy: Doesn't mind when Shaw blows Wilson away as she's called him out on the latter's stupidity in rashly taking a ContractOnTheHitman and given him the compromising evidence he was looking for. He lets her walk out....and makes sure Hersh intercepts her.

* DeadpanSnarker: It becomes gradually more prevalent, but eventually he starts throwing out dry sarcastic quips.

* NotSoDifferent:
** In "[[Recap/PersonOfInterestS03E23 Deus Ex Machina]]", it is shown that she sees Finch as less of an enemy of the state, and more as a kindred spirit and potential ally, someone who has also sacrificed everything to prevent terrorism.
** To Greer. Like him, she doesn't mind killing civilians in her work. But her justifications are different. The first is initially to prevent knowledge of Research from leaking out. The second is if she deems it in the national interest such as in the case of the Irrelevant framed as a terrorist in "Control-Alt-Delete".

* NotSoDifferent:
** Invokes this when meeting Shaw. She agrees entirely.
** On meeting Finch, Special Counsel describes him as an "invisible but powerful" figure [[TheManBehindTheMan operating behind the scenes]], basically the same role that Special Counsel plays (not to mention his own boss, Control).
* PragmaticVillainy: Doesn't mind when Shaw blows Wilson away as she's called him out on the latter's stupidity in rashly taking a ContractOnTheHitman and given him the compromising evidence he was looking for. He lets her walk out....and makes sure Hersh intercepts her.

* EvilCounterpart: Reese describes him as "a lot like me." Hersh [[LampshadeHanging lampshades]] in "Booked Solid" that he and Reese [[NotSoDifferent aren't so different]].

* FamousLastWords: "Fair enough".

* BadassBureaucrat: Perfectly willing to get her hands dirty alongside her subordinates.

* YourCheatingHeart: According to Root, he had been cheating on his wife with another woman for several years.
