Early in the pilot episode, Homeless Bum Reese is harassed by a group of lowlifes punks. He hands them their asses. Later, when he needs weapons, he tracks down the same punks to a gun deal, corrects their gun handling ("You're holding it sideways. That means you can't aim."), takes them all down in about 10 seconds with one of their own guns and simply gathers up what he needs from the pile of ordnance on the table. Their ringleader is left standing, dumbfounded. Reese tells him to get some safety training and leaves. And he never once raises his voice.
"Have a nice day."
Reese then puts what came to be known as the "Plan B bag" to good use. He ambushes a SUV with a hostage in it by firing a tear gas canister dead on through the windscreen with his new projectile launcher, causing it to crash, then walking towards the car, he kneecaps a hostage taker with his new Weapon of Choice and finishes off the second man by hitting him in the face with the bag.
Also from the Pilot episode; a handcuffed Reese escapes from the backseat of an unmarked NYPD cruiser by setting off a flashbang underneath the driver's seat, and then after the car wrecks he simply kicks out the back window, frees himself, and walks away... after stopping to shoot the Dirty Cop four times in the back. At point blank range. Not to worry though, he made sure that he was wearing a bullet proof vest first.
Reese switches the recording the POI was using with one that exposed her criminal activities. She plays it in the middle of a packed court room preventing her from pulling off a Karma Houdini
In "Ghost", the main bad guy is driving away after confirming with his hitman the location of the POI. Not to worry, Reese comes out of nowhere and ambushes the man's car with a dump truck.
Harold may not be a former CIA agent, but when push comes to shove, he helped stall the hitman for some time with the creative use of a phone and lamp and was willing to take the bullet for the POI when they got cornered.
In "Mission Creep", Reese is having a drink with the latest Person of Interest when two eavesdropping bankers interfere with their conversation and one tells Reese that returning soldiers should learn to adapt and he should use his head. Reese shows him just how he uses his head.
In the climax of the episode, the main antagonist has sabotaged the submachineguns of his bank robbery crew and is leisurely murdering them with a silenced pistol. He doesn't count on Reese packing a fully automatic Glock 18 machine pistol as a backup weapon however and is forced to flee when Reese lays down suppressing fire.
Reese's confrontation with Andrew Benton at the end of "Cura Te Ipsum," combined with its No Ending conclusion.
"Maybe it's up to me to do what the good people can't. Or maybe there are no good people, only good decisions. . . . Andrew, help me make a good decision."
The Car Trunk of Doom in "Judgement", where Reese interrogates a suspect by tying him up, dumping him in the trunk of a car, and then going for a joy-ride. It works, too.
"The longest it's ever taken me to break someone is 16 hours. You don't look like you're gonna set a record."
Mr. Finch confronting Keller at the end of "The Fix" reminds us that he is, in his own way, just as dangerous as Mr. Reese.
Finch: "I know that the only thing you do care about is money. So that's what I'm going to take from you. Your money. All of it."
"Witness": the reveal of the Magnificent Bastard Carl Elias When the Yogorovs finally inform Carter and John who they were actually looking for, Charlie Burton, the meek, Deadpan Snarker school teacher transforms into a professional and pragmatic criminal mastermind, utterly catching John off guard with a Dramatic Gun Cock After forcing John to tie himself to the rail, he kneecaps one of the Yogorovs, calmly walks off the east river ferry where his bodyguard who knocked out Fusco is waiting and to the tune of the Awesome Music "Sinnerman" casually strolls off to his SUV which zooms away by the time Harold arrives.
Later he has a lone gunman break into the Yogorov offices and double tap the patriarch of the family, forcing the Russian Mafia to cede control of Brighton Beach, the place where Carl's father used to run before being arrested
Carter demands that Finch explain what he and his partner are doing. Finch gives Carter a number (A man who lost his job, home, and family, and holds a grudge against the banker who foreclosed on him). Within seconds of Carter figuring out what will happen and taking down the PoI right before he can kill his target, she gets a call on her cell phone.
Finch: That, Detective Carter, is what we do.
"Root Cause" Reese fights off a hired killer and knocks him out by ripping a public bathroom hand dryer out of a wall and slamming it on the man's skull.
In the climax of "Risk", the POI gets even with the colleague that betrayed him and the Jerk Ass corrupt SEC official who both tried to have him murdered and caused his uncle and dozens of investors to lose their money by bankrupting them both completely with Finch's assistance.
"Flesh And Blood" A young Elias, not yet the Magnificent Bastard crime lord is taken away to be executed by two enforcers. He fights back, takes control of the garotte one of his executioners is using and turns the tables on both of his would be killers.
Finch, with nothing but words and a few photographs, walking up to one of the head cops in a corrupt cop ring on his own and manipulating him into stopping HR from working with Elias. This is where their conversation ends:
Officer Simmons: What do you want?
Finch: You need to get me the location of Detective Carter's son and call off any men you have working on Elias's behalf. HR severs its ties with Elias as of this moment.
Carter using each of the items in the Plan B bag in order to hold off the hit squads Elias has sent after the New York Dons.
Reese rescuing Carter's kidnapped son has to be seen to be believed.
One of the Smug Snake Dons who's secretly made a deal with Elias grabs Fusco's backup revolver and tries to force Carter and Fusco to let Elias into the safehouse. They gun him down in response
Elias gets one in the end of "Flesh and Blood", he may have initially failed in his goal to kill off his targets but gets an excellent consolation prize when he has his Father and his half brother killed in a car bomb. The surviving Don later makes peace with Elias, and thus accomplishing his aim of taking control of New York's criminal underworld.
"No Good Deed" Despite getting wiped out by Reese in the end, the ISA hit squad acquitted themselves very well in their mission to kill Henry Peck. When Reese is escaping with Peck in a cab, they set up a nearly successful ambush with their team sniper disabling the taxi cab by detonating the fuel tank with a single shot.
"Firewall", Root's plan to capture Harold, become a POI, get into a situation where John and Harold are separated and take the latter hostage, utterly outwitting the normally Properly Paranoid Team Machine
Finch hacking all the cell towers north of Canal Street and cutting off all cell communication except for the phones he chose, saving John and the POI from being incinerated by the sabotaged gas main the HR hit squad was trying to use to kill them and destroy the hotel floor they were on in the process.
Halfway through "Firewall", after Fusco and Carter discover they were Working the Same Case, they come to the rescue, arresting all the HR guys on site.
Later, when they're all chasing a car with some HR mooks who were able to get out of the parking garage, Reese tells Carter to slow down....and detonates the explosives that were kept in the HR vehicle beforehand killing the occupants of the car. The utterly shocked looks of Carter and Fusco who Didn't See That Coming make it even better.
When Nathan Ingram first reveals the Machine to Alicia Corwin and Denton Weeks, he gives them the first number, and refuses to divulge the Machine's secrets. Weeks attempts leverage by threatening to renegotiate the contract... and Alicia tells him that Nathan is selling the Machine to the US government forone dollar.
In "Contingency" a neo-Nazi threatens Reese with an Angry Guard Dog. Reese recognizes that it is a highly trained military dog and he worked with this type of guard dog before. He also knows that there are only three people in the world who train these dogs for the US military and they all train the dogs to obey commands in Dutch. Reese shouts a few commands in Dutch, the dog lies down and a few minutes later the neo-Nazi is flying out a window.
Becomes a CMoH when Reese basically adopts the dog.
The 'negotiation' with the Machine in "The Contingency," when Reese basically blackmails it into helping him. It has actually been compared to a staring contest between two Mack trucks. The part that makes it really awesome? Reese wins.
Reese managing to track down Root is a very impressive feat considering how skilled the woman is with computers, specially considering Reese had to act on his own, without Finch's help.
Finch gets one for quickly getting John's attention in the train station and bravely jumping on Root's arm, causing her to miss when she attempts to shoot a bystander, and he does all this after Root pumped him with a sedative.
Fusco tracks down villain-of-the-week Monty and goes Big Damn Heroes on his ass, saving the girl from a certain death. Monty recovers, puts him at gunpoint and mocks his bad shape "You think you can outrun me?", Fusco stares and answers with a smile "Lemme mull that over for a second." Cue Reese hitting him with a car and Fusco taunting back "Yep, pretty sure I can outrun you." Very impressive for the resident Butt Monkey.
In that same episode, Reese eliminates an assassin with the creative use of a nail gun.
Finch hacks into the POI's electronically controlled prosthetic arm and manipulates it into leaving a GPS trail so they can track him. Added bonus points for doing it while riding on the back of a speeding motorcycle.
"... Which means that contained within this string of decimals is every single other number. Your birth date, combination to your locker, your Social Security number. It's all in there somewhere. and if you convert these decimals into letters, you would have every word that ever existed in every possible combination. The first syllable you spoke as a baby, the name of your latest crush. Your entire life story from beginning to end. Everything we ever say or do... all of the world's infinite possibilities rest within this one simple circle. Now, what you do with that information... what it's good for... well, that would be up to you."
And then later, when trying to convince Caleb not to kill himself to atone for getting his brother killed accidentally two years earlier, we get this gem:
"Your mistakes, like mine, are part of who you are now. You can't move on from that. Believe me. I've made a sizable number. But... sometimes your mistakes can surprise you. My biggest mistake, for instance... brought me here. At exactly this moment when you might need some help." And the best part is that he succeeds. Doubles as a Crowning Moment of Heartwarming and Tear Jerker as Finch alludes to the events which separated him from his Only Friend and fiancée in the past, seeing himself in Caleb and not wanting him to make the same mistake like he did.
Finch dressing up as a false correctionals officer, complete with menacing-looking tear gas grenade launcher, to prepare to get Reese out of Rikers. Also, working on the fly to out-flank and out-match Donnelly's determined search for "The Man in the Suit".
Carter, interrogating one of the mercenaries and pushing his hot buttons just enough that he loses his temper and frames himself as "the Man in the Suit."
Finch gets an Off Screen Moment Of Awesome when he apparently climbs 21 flights of stairs in order to help John, despite the fact that he has a bad leg.
Also for defusing the bomb with only 0:07 seconds to spare!
Fusco taking out two highly trained killers in 3 seconds with a little misdirection and a few well placed hits.
Reese punching the Smug Snake hotel manager in the face.
Reese vs. Hersh.
ISA agent Samantha Shaw gets lots of these over the course of the episode, but a standout is when she disarms a tactical team member, stuffs the man's flashbang grenade into his gas mask and sets it off, rides the man's body through the window down a two story drop, and then finally finishes the Mook off with her pistol. Reese gets his own offscreen moment during the same sequence when, immediately after being shot seven times in the body armor by Shaw's submachine gun, he immediately gets up and takes on a second tactical team to cover Shaw's escape. After Shaw gets outside we see her limping past two men that Reese had kneecapped on his way in.
Also, Wilson (Shaw's immediate boss) gets one during the same sequence, he is being shot at by Shaw (quite possibly the most dangerous person in the entire series after Reese) and all he does is stand there chewing gum. In the following scene he appears not even slightly fazed by the whole thing.
At the climax, Shaw finally meets with the special counsel and Wilson. She calls Wilson out on stupidly taking a Contract on the Hitman when other options were available to solve the problem and then resigns from the ISA in the most epic way possible by plugging Wilson in the chest and walks out with the Awesome Music "Future Starts Slow" kicking in.
Proteus has Finch confronting a identity stealing-serial killer.Not So Stoic doesn't even begin to describe it.
Man: One day I'll stop when I find the person I'm meant to be.
The POI in 'All In' gets one. When he goes in to gamble and win back the money he lost from being a money launderer, he uses very, very impressive sleight of hand moves to continually win at Baccarat till he earns the money back. He used the same trick on Finch to avoid answering his questions and give him the slip.
And the capper, "Hey dumbass!I cheated!" He had used those skills to steal the bullet out of a gun right before being forced to play Russian Roulette.
"Trojan Horse": It seemed like just everything about this episode was made of awesome.
For starters, Reese casually shoulder-checking the R&D boss to grab the USB stick for Finch.
Samantha Shaw sneaking up on Reese. And then sneaking up on Finch!
Reese had multiple moments of awesome, taking out three security mooks in rapid succession.
"In Extremis": Reese literally serving up some Karmic Death to this episodes villain.
Simmons is gob smacked when he finds Carter has moved Stills corpse, utterly wiping the smug grin on his face when he was about to get Fusco arrested for Stills murder.
"Zero Day" features Reese and Shaw, side-by-side, opening a can of whupass upon some Decima Technolgies thugs. It's specially good when Reese ends up locked in a fist-fight with a Giant Mook at the end of the line.
On the villains end, one must admire Greer for staying completely preoccupied as ReeseandShaw come blasting in. He even greets them politely, not even slightly threatened by the fact these two unstoppable former US Government Hitmen are pointing guns at his unarmed self and have every reason to gun him down.
Reese and Shaw casually dispatching the "irrelevant" perpetrator at the wedding and protecting the "irrelevant" victim of the Russian mob, all the while being guided by The Machine.
Earlier, at the pay phone, the Machine warns Reese where the Decima goons are coming from. Reese casually oneshots them. Yes, the Machine is calling out their positions, but it's still dark and Reese is using a pistol with just iron sights. And every single one of his bullets is an incapacitating shot.
...and if that's not awesome enough, he's left-handed, but he's shooting with his right (non-dominant) hand because he's holding the phone in his left.
Root also gets a similar ability and is able to actually command the machine to customise hers.
Finch having made the virus that Decima was using to try to take The Machine down, and subverting it. Finch knew that sooner or later someone would try to gain control of the machine and infect it with a virus... so what Finch is that he sent his own virus into the world, and built it so that it would allow the Machine to protect itself. That's right, Finch played Decima into vaccinating the Machine for him!
"I always knew there was someone behind Ingram — like a black hole — invisible, but powerful."
Reese's style of hostage negotiation leaves a team of Mexican Drug Cartel members in a fatal car crash and a consul official's son alive.
Shaw's first job as a member of Team Machine. We think she's having some time out but when gunmen in black SUV's pull in front of the horse and carriage she's in with the POI, she pulls off an excellent Guns Akimbo, eliminating the Mooks before they can open fire.
The POI's introductory scene, where he responds to a threat by calmly giving a play-by-play of the Bar Brawl that's about to ensue. Even Reese is impressed.
Fusco disarming the bomb. Bear in mind, he's not trained in bomb disposal and yet with John's scant advice succeeds in defusing it, saving R.J.
John casually strolling into the jewelery store during a Mexican Standoff.
If you're going to ambush somebody use a muzzle suppressor. Losers.
In the arm, through a brick wall, in the dark. You're welcome.
Root drives a hard bargain with her therapist. When he takes away the cellphone, she lays out several unsavoury facts she had no way of knowing in order to creep him out and prove that the machine is talking to her.
"Nothing To Hide": Say what you want about Peter Collier, but his elegantly destructive scheme to destroy the POI is relatively admirable in it's execution.
Shaw and Carter taking out the two hit men.
Root, with The Machine's help, blasts her way through her mental asylum. The machine helps give her the correct mixture of pharmaceuticals she needs to put together a quick knockout gas, which she uses to eliminate the asylum's security. Then in a gigantic shoot out, Root successfully holds off Hersh, who was trying to kill her, getting the better of him, and escaping.
Bonus awesomeness for reacting two seconds before Hersh stepped into the corridor catching him off guard and forcing him to go into cover and then shooting Hersh behind her back, relying on the Machine for aiming, qualifying for Crazy Awesome.
Finch and Reese getting Bear to act for all the world like a sick dog so they could have a reason to be at their veterinarian's in time to save her. In a perfectly coordinated Curb-Stomp Battle, the team wipes out the criminals who were trying to rob the Veternarian. Bear acquits himself well, taking out the final hostile who was using the POI as a Human Shield.
Fusco grabbing the letter opener from Shaw without a thought as to whether his own safety was at risk.
A extremely fed up Reese lets the armed Asshole Victim POI and her husband to kill each other, placing a pistol on the table for the unarmed husband to grab. Led to by his beautiful quote:
"I'm in the business of stopping bad things from happening. I'm not sure what's about to happen here is a bad thing."
The icing on the cake is when Reese unties the mooring line of the POI's yacht, letting it drift away and walking off as two gunshots ring out.
The ten year old POI who's an amateur expert in spying spots Shaw, the trained professional conducting surveillance on her. This gets a laugh from Reese.
Reese: Finch, you're not going to believe this. Shaw just got made by a ten year old''
The ten year old PoI conducts her own amateur surveillance operation on a bunch of criminals and records hours of tapes outlining the criminal alliance between the Bratva and HR. Normally, something like this would be the crowning achievement of an FBI taskforce and she did it on her own using an old tape recorder.
Carter delivers a superb "The Reason You Suck" Speech to her Bitch in Sheep's Clothing partner who she knew from the beginning was an HR mole, points out she's made sure his mission was a failure by feeding him mostly false information, kills his associate (who was trying to shoot her) with her partner's personal handgun, and blackmails him into serving her. The shocked look on his face as he realises the tables have been turned makes it all the more satisfying after he previously delivered a venomous Motive Rant.
Carter: You don't work for HR anymore, son. You work for me
Shaw interrogates the POI's drug-addled cousin Vadim, who's been neglectful of Gen and gave her up to the Russian Mafia, using the promise of more drugs to entice his cooperation. After getting what she wants, Shaw pours out some powder on the glass coffee table and hands Vadim a rolled-up dollar bill so he can get a snort—and then smashes his face into the coffee table, leaving him in a messy heap in the wreckage of his apartment.
Shaw completely ignoring her injuries for most of the episode, and when she does finally treat them? She does so by raiding an ambulance, taking out Russian thugs, and then forcibly extracting the head Russian's blood. Then she calls Simmons and and forces him to put the girl on.
Root's entire scheme.
Credit where credit is due, Root was just following orders (admittedly with her usual flair). The entire plan was the Machine herself being The Chessmaster.
The Machine also gets points for becoming exponentially better at her predictions. Almost a day before it went down, she predicted Collier and Vigilance would snatch the POI and assassinate his hacker brother, so she arranged for Root to be turned in to the CIA, arranged an escape route and new life for the hacker, alerted Team Machine to the POI, prompted Root to put aside a backup gun... The Machine is showing the makings of becoming an excellent schemer. And it was almost elegant the way it arranged to take care of Collier's group from two directions - and so while Collier was so focused on Reese, he didn't see Shaw and Root coming.
The ambush itself was full of awesome. Initially things go well for Vigilance with Collier using some exploding paint cans to crash the CIA prisoner transport. He's then able to pin down Reese with his gun while his men get to work hunting for their target. However, Reese begins to fight back while Root, who's broken out of the prisoner transport and packed her own machine pistol under a park bench recovers it and begins mowing down much of the Vigilance hit squad, even trading shots with Collier in slow motion when they go for the Sloan brothers. Later she gets cornered by the survivors of the Vigilance team but they notice she's beaming even when they have her dead to rights. Cue Shaw pulling a Big Damn Heroes moment and gunning them down from behind.
Shaw makes a wielding torch out of Spaghetti and an oxygen bottle.
Shaw's reaction to hearing her job with Root is done. She promptly punches Root in the jaw knocking her out.
Finch's Shut Up, Hannibal! to Root, after she accuses him of going against the Machine's wishes by keeping her captive. He makes her doubt the Machine.
Carter pulling off her The Chessmaster act to brilliance. She conducts a complex series of false flag operations trying to start a war between the Russian Mafia and HR in order to get revenge for the events of Season 2, and it works! Leaving the head of HR in a floundering mess and the Yogorov family crying for blood.
She gets Carl Elias to deliver her intelligence on the 38 HR members to the current head of the Yogorov family and he even cooks pasta for the man who has every reason to kill him and lives.
The highlight of Carter's scheming is when using a sniper rifle she attacks Quinn in his office in broad daylight in order to goad him into making a mistake by making him believe the Russian Mafia is gunning for him And when he tries to have some Russian Mafia hitman executed she places a phone call to the FBI drastically compromising the security of HR.
Carter sadly seemingly grips the Idiot Ball in the end and walks into an ambush when trying to legally arrest Quinn. But she even prepared for that eventuality and arranged for Harold to listen in on her confrontation with Quinn by hacking his cellphone allowing Reese to burst in at the right moment, intervene and extract Carter and Quinn leaving several HR officers kneecapped in their wake
"Lionel? It is going to be okay."
Villainous one for Officer Patrick Simmons. He may not be an ex-CIA assassin but he gives Team Machine a serious run for their money with his strategic use of HR's resources and criminal contacts when hunting down Reese, Carter and Quinn.
Fusco telling off Simmons et al:
Simmons: From the size and shape of this key, I'd say it opens up a safe deposit box.
Fusco: It's my locker at the Y. You're welcome to my dirty jock.
After being upstaged and repeatedly being treated as the resident Butt Monkey for most of Season 3, Fusco breaks out of his restraints and crushes the windpipe of the HR officer who was about to kill him and does so while severely beaten up and with broken fingers.
Finch readily goes out into the field to recover Reese and with the smooth use of a taser and getting John arrested, he succeeds in saving Reese from the final HR officer gunning for him.
Carter's operation to destroy HR actually succeeds and she even gets reappointed as a detective. But then things take a turn for the worse when Simmons ambushes her along with John.
However, she actually steps in the way of several bullets aimed at John that would have killed him, and sacrifices her life in the process
Even as she goes down Carter is still able to draw her Glock 19 and loose off one accurate round which hits Simmons
"The Devil's Share"
The entire opening, set to Johnny Cash's cover of Hurt. It is a phenomenal piece of cinematography, suceeding in conveying the emotions all the characters are going through, without any sound, just the pictures and the music.
Despite their Tear Jerker nature, John's violent antics are pretty impressive especially since he's conducting them hours after being shot and is slowly bleeding to death.
John's stone cold, bone-chilling speech to Quinn:
John: You do what you say. So do I. I'm not gonna threaten to kill you. I'm going to kill you... whether you tell me or not. No bargaining. In three minutes... you're dead. I've killed many people. Never bothered me much. That's why I was good at it. I didn't like them suffering, though. Took me years to figure out how to do it quickly, painlessly. But if you don't tell me, I'm gonna forget all that, understand? And I'll make the last three minute of your life last forever.
Fusco vs Simmons. It's not as one-sided as the beating Reese gave Simmons five episodes earlier, but Fusco wasn't nearly as well trained and was fighting with one hand in a cast, and still took him down.
His preceding speech is just as brilliant, if not entirely tear jerking:
Fusco:That's just it. I could've been just like you, a bottom-feeder who turns on his own kind. For what? Money, power? I got lucky. I had a partner. She was good for me. For a lot of reasons. She reminded me that I could be good again too. I could be a good father, a good friend. A good cop. I'm not gonna let you undo all the good she did. Carter saved my life. She...she saved me from myself. Because she believed in me. And I'm not gonna throw that away on a piece of crap like you.
Root utilises her "Analogue Interface" status to the fullest extent, disabling multiple Russian thugs with a epic use of Guns Akimbo and Improbable Aiming Skills, even impressing Shaw who despises her.
Elias and Scarface take the time to deal with Simmons permanently when he's trapped on a hospital bed.
Topped by the magnificent final conversation between Simmons and Elias:
Elias: Well, there remains a debt. Civilization rests on the principle that we treat our criminals better than they treated their victims. That we not stoop to their level. But you and I are outliers. We're not really a part of civilization. We're something... older. Which means, of course, that we can do the things that civilized people can't. I offered to kill you for Detective Carter many times, and she always said no. She was civilized to the very end. I don't think she liked me. But I liked her very much. And you killed her. So now I consider it my responsibility to fix the particular problem that is you, Officer Simmons.
Simmons: You really think you're going to be the one to kill me?
Elias: No. No, my friend is going to kill you. I'm just going to watch.
Fusco vs. Reese. Fusco is sick and tired of Reese's trip over the Despair Event Horizon when he starts spouting borderline nihilistic stuff about how nothing matters. So Fusco throws him out of the bar where he was drinking and fights him. Yes, Fusco gets the worse of it (there's that whole problem of fighting someone who's a better fighter than you), but the fact that he can still keep up with Reese just shows how Fusco has grown.
Root: You're too late. The Machine's already talking. You're too old; older than forty. You can't hear sound above fifteen kilohertz... but I can. With the ear I've got left. My friend's been beeping Morse code at that frequency since you brought your phone in here. She's been talking to me the whole time, telling me about you. You're scared of me... even with all these guards watching. By the way, that one has a bum knee. You're so scared of me, that you hid a knife in your pocket. I couldn't reach it. Until you got close enough to cut me...
After the fiasco in Season 2 Greer makes his triumphant return successfully screwing over Northern Lights, Vigilance and Team Machine while making off with the Samaritan Drives.
Not quite as awesome, but definitely a levelling-up for Fusco: casually fielding numerous questions with some Awesomeness by Analysis
Fusco: Wrong edge. Wound was serrated, remember?
Detective Kane: Suspect's guilty as hell, but we can't get his DNA without a warrant. Fusco: Ever heard of dumpster diving, Kane?
Detective Harrison: Tara Cooke, 29. Found by the East River yesterday morning. Head bashed in, wallet stolen. Mugging gone bad, right? (after initially brushing off Harrison) Fusco: See these bruises? Livor mortis. Happens when a body stays in one place, okay? Tara was found on her right side. These bruises are on the left. And look: forensics found industrial carpet fibers stuck in the wound. But she wasn't wrapped up in any carpet. Harrison:(realization) Body was moved.
Reese and Shaw working together to storm the place Aaron was being held - and than as Reese defuses the bomb, Shaw efficiently mops up.
The wounded Decima Technologies agent held captive by Reese and Kara decided to kill himself when he jumped out of the abandoned office floor rather than squealing out to them about his boss, Greer.
Shaw shows up at the end of the episode to utterly demolish the Chinese team and kill Dillinger. If Finch had not managed to keep hidden, it's likely that she would have canceled the series before it even began.
Finch recognizing the code of the machine and plotting the virus within a virus used by Decima on the fly.
Tne Fallen Hero and the Endgame Trilogy
In it's own way, the entire Endgame Trilogy is an ode and love letter to the awesomeness that is Detective Jocelyn Carter, and how one person can change so much around them.
Endgame: Every single one of her friends asks to come to her aid, knowing that she's deliberately inciting a war between the Russians and HR Including Finch, a brilliant but physically meek man, Reese, who could have been Batman in a former life. Shaw, who is at best is autistic, at worst a psychopath (psychopaths exhibit some emotions like anger and fear, sociopaths literally feel nothing). Fusco, former HR who is on their shit list brute force cop, and Elias, a mob boss. With some slight help from Shaw,supplies, and Elias, message delivery, that same cop starts and ends a war between the soldiers of the Russian Mob and HR, leaving only their heads, free, to use one the head of the Russian Mob to get the other the head of HR. All while planning ahead to have no casualties, by calling in the FBI to prevent the dirty cops from killing the Russian mobsters. Then that same cop has the intelligence to realize that she's playing on a field she'll never win, and she calls in her friend Finch and Reese for help with the wrap up.
The Crossing: Joss and John have to make it from Queens to Manhattan and the Federal Building to turn in the head of HR. Every gang and free dirty cop on the street is out to get them except for of course, Elias's men. Fusco saves them from getting caught but gets captured himself. Shaw's his backup and Reese and Joss are alone, when John reveals that Joss saved him from himself in their first meeting by caring enough to ask him if he needed help as a returning veteran (and running his prints just in case) and for putting him in the system for Finch to find. John leaves his suicide bullet behind for her and gets the people on their tail chasing after them so she'll have a clear run to the building, even knowing he is this episode's number and Finch gets in on the action by coming after the both of them with a taser and his wits. Joss gets her man into custody the rest of the way by herself and gets reinstated. After replaying their first meeting, Joss springs "John Doe" and gives her own life to save his from Simmons because John is unarmed (his weapon wasn't registered so it was confiscated.) and without his vest, just after he tells her if he had to die, he hoped it would be with her, because for him, that's the best way to go out. He swears to look in on her son and her final thought, though not completely voiced is for John saying "Don't let this...(change you).
The Devil's Share: After Joss's death you see Finch, Shaw, again autistic or psychopath, and Fusco openly mourning her. And then John gets up out of his hospital bed to rain down hell on the shooter, reverting to the CIA tactics of old John Reese, leaving people to die. And Shaw does the same, even though she has the emotional functions of hungry, angry, violent. Finch while wanting Simmons also wants John and he is slowly killing himself trying to avenge Joss's murder. Harold finally even lets Root in on the action because it's that important that he not lose anyone else to this war. John finds his way to the head of HR and is going to kill him but can't his gun failing on him due to lack of ammunition or his blood clogging the works. Root, Shaw, and Finch save John while mourning the loss of getting the killer, but there's still Fusco on the case, who has already admitted to killing someone in retaliation for a young cop's death. He finds Simmons puts a beatdown on him and then arrest him, professing that working with Joss made him a good cop again.
