!Flesh and Blood

->''"Sometimes I wonder what kind of man I'd be if she hadn't been killed. I hear people change when they lose a parent. Especially when that parent is murdered."''
-->--'''Elias'''

In a flashback to the '80s, a young Carl Elias is bullied in school and resentful because he doesn't know anything about his birth family. His foster mother promises to help Elias track down his father, and by 1991, Elias is a low-level soldier in Don Gianni Morretti's organization. He has a reputation for being resourceful and tenacious and that brings him to the attention of Morretti, who recognizes the name and knows that Elias is his illegitimate son. Morretti promises to help Elias rise up in the ranks, but soon after, under the pretense of a job, he's taken out to the woods by two thugs who have orders to kill Elias the way they killed his mother. Briefly overcome with tears, Elias promises to destroy them all. The thugs attempt to strangle him with razor wire but Elias fights them off, scarring his palms in the process, and shoots both thugs.

In the present day, it becomes apparent that Elias is ready to make his move: Fusco is ordered by Simmons to pass along details of the FBI and Carter's manhunt for "the guy in the suit" and advised to take a few days off work at homicide; Carter learns that Elias' bank accounts have been drained and all $4 million has been parceled out to hundreds of hired goons; and the Machine spits out five separate numbers that correspond to the other dons of the Five Families, plus Tommy Morretti, the son of Don Gianni and half-brother of Elias. Reese offers protection to one of the dons, but he refuses and minutes later is killed by a car bomb triggered by Scarface, Elias' right-hand man. Carter offers police protection to another don, but as she collects him their police backup leaves: Elias has made a deal with HR and all the cops and officials in their pocket are turning a blind eye. The don is killed by a gunman and Carter is only saved by Reese's intervention.

Carter buries the hatchet with Reese and Finch and fills them in on what the NYPD has learned. Finch tracks the money transfers and identifies some of the goons who Elias has paid in the past few days, but when Reese follows them, he learns they're shadowing the families of HR's people, so that Elias can use them as leverage to force HR to cooperate. Meanwhile, Carter goes to the remaining dons and offers them protection, bringing along the only cop she trusts -- Fusco! -- as backup. When the dons refuse to come along, Carter kidnaps them at gunpoint just minutes ahead of Elias' goons attacking. Finch steers them towards a safe-house but HR officers soon find them and cordon off the building. Reese guesses that Elias will try to use Carter's son, Taylor, as leverage to get her cooperation but he doesn't make it in time to prevent Scarface from taking Taylor. Elias calls Carter and threatens to kill Taylor if she doesn't let him have the dons -- people who, he reminds her, make their living by selling guns, drugs and women -- but she refuses. Elias eventually turns up at the safe-house himself, supervising as his goons try to break down the steel-reinforced door.

To get Taylor's location, Finch meets with Simmons and informs him of Elias' surveillance of HR's families. Convinced that Elias isn't a true ally, Simmons passes the information up the chain and HR withdraws its support, and gives up Elias' base of operations. Reese goes and saves Taylor, as well as Don Morretti. At the safe-house, Elias breaks down the door but Carter refuses to hand over the dons; the HR backup leaves and uniformed officers arrive to support Carter, called in by Fusco. Elias is arrested, processed and sent to jail, and Taylor is returned to his mother. Morretti also returns to his son, but as they get into a car, they receive a call from Elias, who managed to get a cell phone in prison, saying goodbye and regretting that he can't be there in person. Moments later, the car explodes.
