Season 1, Episode 23:
I did this corporate training thing once — I was blackmailing the CEO, long story. But they did this exercise called the trust fall where you close your eyes, and fall, and wait for someone to catch you. I knew you boys wouldn't let me down.The latest number is Caroline Turing, a discreet psychologist for some of the wealthiest and most dangerous people in New York. One client in particular, a shady lawyer named Hans, continuously implies that something bad will befall Caroline if she blabs any of his secrets. Meanwhile, Fusco has made a name for himself in HR, enough that he's earned a meeting with the inner council — a city councilman, a high-ranking police officer and a district attorney — and a place as Officer Simmons' right-hand man. To make up for the lack of income since Elias' arrest, HR has expanded into murder-for-hire and their latest target, on behalf of an anonymous well-paying client, is Caroline Turing. Reese and Finch theorise that one of Caroline's clients wants her dead so she won't expose their secrets, so Reese goes undercover as a patient in order to plant cameras and peek in her diary. Finch tries to track the accounts used to pay HR for the hit, to no avail, so he calls in Zoe Morgan to help figure out which of Caroline's clients are likely to have hired HR. Unbeknownst to all, Alicia Corwin has been shadowing Finch and tracks him to the library.Simmons' hired goons set their ambush, but Reese foils the attempt and spirits Caroline to a downtown hotel where they can hide out, and HR follows. Finch calls Carter for backup, but she's dragged away by Agent Donnelly and the FBI task force: they've spotted Reese on the CCTV cameras going into the hotel with Caroline (Donnelly assumes she's a hostage) and are dispatching units to hunt him down. HR's goons enter the hotel and Finch directs Reese and Caroline to the roof where they can steal a helicopter and escape, but the FBI gets there first: they land a tactical response team on the helipad. Reese and Caroline are trapped between the FBI and HR; Finch and Carter feed him info on how to stay undetected, while HR plot to blow up an entire floor of the hotel in order to take Reese out, helped by their "man on the inside". Zoe tracks down "Hans", who is actually a lowlife conman that was hired to be Caroline's patient and threaten her. Finch leaves the library to enact a plan to get Reese and Caroline to safety; while he's gone, Alicia breaks into the library and snoops around.Reese and Caroline make it to the freight elevator, as per Finch's escape plan, but HR's goons attempt to cut them off on level 25. Carter warns Reese in time for him to stop the elevator and he tells Caroline to fiddle with the elevator controls and bypass the floor that HR is on, while the goons plant bombs on level 25 and the FBI come at them from the floor above. Reese and Caroline are out of time and have no options — which is when Finch enacts his plan to hack a rooftop signal dish and knock out all communications (bar a few select frequencies) in Manhattan, styming the FBI and HR's plans and giving Reese and Caroline a chance to escape. Simmons cuts the hotel's CCTV feeds to cover his tracks but Donnelly sees him doing it just before the cameras go out. Carter sees Fusco texting people and confronts him in the bathroom at gunpoint, accusing him of being HR's man. Fusco owns up to being Reese and Finch's agent in the NYPD, to Carter's surprise, but there's no time to compare notes: Finch calls and tells them both to get downtown and help Reese, and Fusco tells her that thanks to his stint as the mole in HR, he knows who they all are and exactly how to bring them down.Reese and Caroline reach the subbasement service tunnels; along their escape route, they find Simmons' car, with something interesting in the trunk. As Finch waits in a car at the rendezvous point by the water, Reese sends Caroline ahead while he holds off Simmons and the HR goons — but it's not Caroline who gets into the car, but Alicia, with a gun, who demands that Finch tell her how to shut down the Machine. She's tired of running, she explains, but Finch tries to convince her it's not the Machine she's been running and hiding from — and not the Machine that killed Nathan, like she suggests — but rather the people who control it. He takes umbridge with Alicia's comments about who is and isn't the "wrong type of people" to have access to the Machine, accusing her of hiring HR to kill Caroline specifically to draw him out, but Alicia has no idea what he's talking about. Meanwhile, Reese is pinned down and almost out of ammunition when Carter and Fusco arrive to bail him out. The goons try to escape in Simmons' car (Simmons himself just hides) and Reese, Carter, Fusco pursue, but the chase only goes on long enough for the goons to get out in the open before Reese activates the explosives he hid in the car, killing the goons. And in the city, Zoe breaks into Caroline's office and finds that a lot of the photos and diplomas are fake. When she tries to access Caroline's laptop, the system files auto-delete and leave a single line of computer code: "ROOT"."Caroline" shoots Alicia in the head as she gets into Finch's car, introducing herself as Root; she hired HR herself in order to lure out Finch, likening it to the "trust fall". She tells Finch they have a lot to talk about and forces him, at gunpoint, to drive off. Later, Reese finds Alicia's body on the waterfront. Thanks to Carter and Fusco, Donnelly recieves evidence incriminating everyone in HR and the inner council is arrested, but Simmons slips away. Reese returns to the library with no idea what to do next, so he walks out onto a street corner and stares up at a surveillance camera.
Reese: He's in danger now, because he was working for you. So you're gonna help me get him back.The Machine processes this for a moment. Then the nearest payphone rings, and Reese answers. Roll credits, and cue screaming fans.
