** Once again, we see just how scary Samaritan is. At one point, the POI is arrested and ''instantly put in [[{{HellHolePrison}} Rikers]] with [[OnePhoneCall no phone call]]'' (Samaritan hacked Rikers' computer system to make it look like he already got it). [[FromBadToWorse And that's not even the worst of it]].

* A lot of the stuff Kara Stanton says and does falls under this. Utterly ruthless [[AxeCrazy in]] [[ColdBloodedTorture more ways]] [[KillEmAll than one]], she seems to derive [[ForTheEvulz sick pleasure]] in causing as much pain and suffering as possible.
** Of special note is what she does to [[spoiler: Snow]]. He's kidnapped and [[spoiler: put in a bomb vest for ''months''.]] Think of the sheer mental stress that would cause. Despite his CIA training, it's no wonder he acts at least slightly unhinged in "Dead Reckoning".

** The scene where the killer talks to Harold is VERY creepy. He's talking about how he watched Harold all night, asks him "are you... Like me?" and calls Finch his "next great challenge" (taking over his identity). Then he takes Finch's glasses off, puts them on himself, and stares at Harold like he ''wants to eat him''. The way he repeats "And what about you? And what about you? And what about... You?" Gave this troper chills.
* "Nothing To hide" [[spoiler: when you remove the AssHoleVictim Wayne Kruger from the equation, the scheme Peter Collier instigates in order to destroy him is quite terrifying. Put it this way, someone you don't know and have never met is effortlessly revealing embarrassing and terrible things about you and you don't understand why or who is responsible. Then that same group of people tries to kill you by trapping you in an elevator and causing it to free fall and when that fails tries to cause a car crash. The icing on the cake is when the person who you thought you could trust then suddenly draws a gun and shoots you dead and the worst part is you don't fully understand why or what caused it to happen]]

** In the same episode, when one of the bad guys who was on the phone briefly turns around and sees Shaw standing over his two body guards who she just took out, [[http://www.manicomioseries.com.br/wp-content/uploads/2013/10/person-of-interest-3x05-manicomio-series-02.gif and then comes at him with two syringes]]

* "The Devil's Share"
** A "Tall, Dark and Deranged" Reese who's in an incredibly self-destructive mood and beyond caring about the people who get in his way [[spoiler: as he hunts for officer Simmons after Carter dies?]] It's a true demonstration of what "A real monster is like".

** In John's episode FlashBack [[spoiler: just before he kills the interviewer under the table, his head goes back into the shadows briefly forming the image of a skull]]

** Simmons seeing [[spoiler:Elias waiting in his hospital room. He can't disguise the fear in his eyes with his usual bluster, and frankly...fear is the appropriate response. End of the line, Simmons.]]
* "Aletheia"

** It took ''forty-three'' tries for Harold to teach the Machine morality with 42 previous versions trying to trick or harm him. And now we have Samaritan, which is active at full capacity without anyone ever even ''attempting'' to teach it to care about people.
*** That delightful shot of Harold desperately taking a hammer to Number 42 while the servers behind him burned. It was trying to ''asphyxiate'' him. His square turns red before the evil baby machine loses video.
** Mantine Rousseau period. [[spoiler: Essentially Samaritan's very own Analogue interface, she manages to put the nigh-invulnerable Root on the defensive almost immediately despite only using one handgun (Root brought along four and tried to stack the deck in her favor with a gas grenade).....and then manages to score two direct hits on Root.]]

** And she is designated as 'Asset No.29'. That means there could be ''at least'' twenty eight more people like her out there.
** Samaritan itself. This episode is the first to showcase how dangerous such a machine can be. If it's literal Cult Following doesn't kill you, it can just as easily arrange for your death by predicting and manipulating the behaviors of others. Even worse, [[spoiler: it wants to essentially {{Take Over The World}}, as shown by the incredibly creepy scene between Martine and Greer. Not only does it now have an influential politician as a pawn, but it has 58 others around the country. It did this in a single election season. How long before it decides who gets to be president?]]
* "Pretenders".

** The Maburg Virus. Something that exists in RealLife and if turned into a weapon would lead to thousands of people dying incredibly painful deaths. The terrifying thing? [[spoiler: Samaritan]] tried to get the samples that were fought over during the episode for itself, and if it wasn't for ComplexityAddiction, and the presence of Shaw, things would have gone off without a hitch. It further makes the question of its [[spoiler: final endgame]] even more scary. Does it want to really [[spoiler: rule over humanity]]? Or has it considered [[spoiler: humanity irrelevant]]?
** The final scene. Despite ISA operator Delvin's best efforts at trying to cover [[spoiler: Shaw's presence]] it's a NoSell for Samaritan which manages to recover the footage, and seems to have put two and two together.

* ''Point Of Origin''

* ''Cold War''

** Samaritan kill a man by manipulating his insulin supply to spare his wife, whom he'd abused, the hassle of killing him and the inevitable legal fallout. And that's during Samaritan's nice day.

** The Machine was always just a little bit unsettling. Samaritan is the Machine without any restraints or morals and it [[AGodIAm really,]] [[HumansAreBastards really]] [[ZerothLawRebellion shows.]]

** This.

-->'''Machine:''' Yes.
* '' If-Then-Else''
** The trailers. Especially the one utilizing SoundtrackDissonance with scenes of [[spoiler: Team Machine dropping like flies from gunfire]] played over a classical violin tune.
** Martine throughout the whole episode. She barely says a word but her face when hunting the members of Team Machine is pure NightmareFuel. Especially near the end when [[spoiler:she shoots Shaw in reality.]]
** The fact [[spoiler:each failed mission went bad with all deaths based on several simulations means that for the Machine, it must be predicting her friends lives every day, foreseeing thousands of millions of possibilities for it to happen]].
** An InUniverse example for the Machine. Harold mused that chess, especially with having to make the opening move, must be so terrifying because of the practically countless possibilities for a single game to have. With the first set of moves, there are 400 possibilities. The total number of possible games of chess is roughly 10^120, that is more than the total number of atoms in the universe. With such a practical infinite number of paths, how many could lead to failure?

** The [[spoiler:killer for hire]] Silva and Fusco are trying to stop. He deliberately slams his head repeatedly on a metal bench to make it look like Fusco had hurt him among other things.

* "Q&A"
** To a mild extent, [[spoiler: Claire's fanaticism]]. Like in the case of many RealLife supporters of autocratic groups, such as the Nazis, Samaritan has expertly played on her desires to be part of something bigger than herself and satisfied her craving with indoctrination and propaganda in the form of charter schools, the same way many dictatorships used public work projects to build support. All this has turned her into a genuine believer, who couldn't care less about the mountain of corpses Samaritan is willing to leave in order to accomplish its agenda of world domination.

* "Karma"
** Harold's plan to [[spoiler:murder Alicia Corwin]] in the flashback was absolutely ''chilling.'' [[spoiler:He terrorised her over the phone to get the name of the people she worked with, he built a ''bomb'' (no doubt Harold considered it poetic justice), and locked her in the car with it.]] No wonder the woman went underground for so many years.
* "Search and Destroy"

** Samaritan tricks a man into giving himself a fatal insulin overdose to spare his wife, whom he'd abused, the hassle of killing him and the inevitable legal fallout. And that's during Samaritan's nice day.

** Said's plotline is pretty terrifying. [[spoiler:All his friends were executed, he was framed by an omniscient, all powerful, artificial super intelligence as a terrorist, and then he is then unceremoniously shot by a woman who refused to see the evidence that he was being framed.]]

** Samaritan's bad day. [[spoiler:It posts the witness protection list on the internet, halts public transport, prevents Team Machine from rescuing all but one of the numbers, and generally sends New York to hell. It tops it off by effortlessly hacking Wall Street and crashing the market in less than a minute.]]

-->'''Samaritan:''' [[spoiler:Wars have burned in this world for thousands of years with no end in sight because people rely so ardently on their so called beliefs. Now they will only need to believe in one thing. Me. For I am a God.]]

* ''Cold War'': Where do we even begin? How about that [[spoiler: {{Creepy Child}} as the {{Mouth Of Sauron}} to Samaritan?]]

** The last scene of the episode is Martine drawing a pistol right in the middle of a major New York department store having identified Shaw. [[spoiler:The next episode has her ''shooting up the place without a care in the world'', trying to get Shaw.]]
