*** A third one from the same episode. When Reese goes and grabs a liquid nitrogen canister off the street, the phone company really does keep [[https://www.youtube.com/watch?v=juZqGU9iuq0 canisters of LN2 on the streets of New York]] which they use to keep the phone wires dry and in an oxygen free environment. The show did use the wrong type of compressed gas canister (it's one for storing regular N2 not LN2) but the existence of the LN2 is correct.

-->'''Finch:''' We are being watched. The government has a secret system –\\

'''Greer:''' You granted the ablity to see everything: to index, order, and control the lives of ordinary people.\\

** Root being very cheerful and/or polite at unusual situations.

** A [[StockSchtick Man in a Suit walks into]] a BadGuyBar. Cue BarBrawl, often involving a BattleDisrectionShot culminating in a DestinationDefenestration.
** Shaw always insists on driving. [[spoiler:It's amusing until you realise the reason for this: her father was killed in a car accident while she was in the car with him.]] Also Shaw always being in the mood for food (often involving InappropriateHunger).
** The Machine keeps sending Root on [[HeroOfAnotherStory mysterious off-screen missions]] which are [[NoodleIncident never fully explained]], even to her. To the total befuddlement of Finch, who keeps encountering Root in often bizarre disguises.

** People getting [[PunkInTheTrunk thrown in trunks]] by members of Team Machine, usually Reese. Sometimes they end up in the trunk themselves.

** Reese always gets into fights and/or thrown out of bars and restaurants.
** Shaw always insists on driving. [[spoiler:It's amusing until you realise the reason for this: her father was killed in a car accident while she was in the car with him.]]
** The Machine keeps sending Root on [[HeroOfAnotherStory mysterious off-screen missions]] which are [[NoodleIncident never fully explained]], even to her.
** Ringing payphones.
** The sound of empty shell casings hitting the ground.

** Shaw always being on the mood for food.

* RefugeInAudacity: Who would honestly expect the murderer of [[spoiler:Cal Beecher]] to stand up in front of a bunch of cops and give the man's eulogy?

** In Season 4, with Samaritan online, Finch's first statement changes to "We are being watched."

* NotSoDifferent:

* [[OneSteveLimit One Sam Limit]]: Averted, but only by a technicality. There's Sameen Shaw, who goes by "Sam", and Sam Groves, who prefers to be known as [[spoiler:"Root"]].

** And then Finch's reaction when Sam Shaw tracks him down, '''''inside the library''''', which to his knowledge has never been compromised.[[note]]Note that Alicia Corwin sucessfully trailed Finch to the library in "Firewall", broke into the library, bypassed his security measures and copied the Irrelevant list, but he does not seem to be aware of this. (Probably because Root shot Alicia before she could say anything.)[[/note]]

** Season 4 introduces a Decima operative named Martine Rousseau, who comes off as, basically, evil Root. Well, ''amoral'' Root. Which kinda makes her just "Root". [[Characters/PersonOfInterestDecimaTechnologies More on the character page]].

* OddlySmallOrganization: The team originally consisted of Reese, Finch, and a giant all seeing super computer. Over the course of the series, we've added Carter, Fusco, Bear the dog, and Sam Shaw as regular members, and Zoe Morgan and Leon Tao as recurring independent contractors.

*** Used explicitly in "The Contingency" where Finch admits they are alike. However that episode also shows how they're not alike, as Finch does not share her LackOfEmpathy (but this is shown to change later on in "/" ""Root Path" when it is show that Root 'is' capable empathy and carries a fare share of guilt.).

*** Used explicitly in "The Contingency" where Finch admits they are alike. However that episode also shows how they're not alike, as Finch does not share her LackOfEmpathy.

* OvertRendezvous: Reese and Finch often meet in public to discuss their cases.
