To stop them, Desai destroys all bridges and tunnels into Manhattan. Setrakian and Dutch retrieve the Lumen before finding a new hideout. Setrakian discovers a clue within in the Lumen symbols before he collapses. Eph returns to New York with Alex and reunites with Dutch and Setrakian. Eph treats Setrakian with free medical supplies from Gus. Creem, angry over Gus ' generosity, tries cutting a deal with the Master in exchange for Setrakian 's location but he is turned instead. Setrakian gives Eph the formula to make him the restorative white. While Eph and Dutch are away, Setrakian has another revelation about the Lumen but Eichhorst and Creem arrive. Alex is killed and Eichhorst beats Setrakian. Gus, with Raul, returns to Setrakian 's hideout, forcing Eichhorst to flee. Raul is killed and Creem ambushes Gus. Setrakian impales Eichhorst, saving Gus, who kills Creem. Eichhorst stings Setrakian and starts draining him, but Setrakian has taken a massive dose of the blood thinner that Eph gave him, poisoning his old foe. Setrakian speaks to the Master through Eichhorst, warning that the Master 's defeat is inevitable. He then beheads Eichhorst. 44 8 `` Extraction '' Paco Cabezas Liz Phang September 3, 2017 ( 2017 - 09 - 03 ) XSN04008 1.01 Eph and Dutch return to the hideout to find Eichhorst, Alex, and Creem are dead and Setrakian infected and dying. Fet, Quinlan, and Roman procure a boat and sneak the nuclear bomb into Manhattan and hide it at the Federal Reserve Bank. Fet and Quinlan leave Roman to guard the bomb, then locate the others at the hideout. Setrakian shares that rather than using the bomb, the Master can be defeated by separating him from his collaborators. Setrakian then asks to be released, and Quinlan beheads him. Eph, Dutch, Fet, Gus, and several cohorts infiltrate the blood center, freeing the captives and apprehending Desai to uncover the Master 's whereabouts. Meanwhile, the Master tasks Zach with an important mission. Eph learns that Zach has been spotted near the market by Harlem River and finds him there. 45 9 `` The Traitor '' Jennifer Lynch David Weddle & Bradley Thompson September 10, 2017 ( 2017 - 09 - 10 ) XSN04009 0.84 Fet and Dutch interrogate Desai, to no avail. However, after Quinlan threatens to drain his wife, Desai reveals the Master 's location. Gus arrives to help Roman guard the bomb and also gather silver from the Federal Reserve Bank for weapons against the strigoi. Meanwhile, Eph doubts Zach 's account of his time with the Master. When Zach purposely leaves a blood scent for the Feelers, Eph realizes his betrayal. Zach confesses he lied and offers to spare his father if he tells him where the nuke is hidden. Eph almost kills Zach but leaves him behind when the team immediately evacuate and meet up with Gus and Roman. The Master arrives and berates Zach for his failure. To save himself, Desai falsely accuses his wife of betraying the Master, but the Master kills both. The team sets off to detonate the nuke at the Empire State Building. Quinlan enters with the detonator, finding the Master gone. When strigoi surround him, he radios the others to leave, but a strigoi horde blocks their escape. 46 10 `` The Last Stand '' J. Miles Dale Chuck Hogan & Carlton Cuse September 17, 2017 ( 2017 - 09 - 17 ) XSN04010 TBD Eph, Fet, and Dutch escape with the nuke while Gus and Roman hold off the strigoi horde. The former regroup with Quinlan and devise a plan to lure the Master into a subterranean tunnel deep beneath the city, where they will detonate the nuke. To Dutch 's dismay, Fet volunteers to detonate the bomb, sacrificing himself. Dutch reveals her feelings for him, but his resolve remains unchanged. The Master orders a final purge of Manhattan to flush out the team and the nuke, an act that shocks Zach. Eph and Fet draw out the Master by deliberately revealing themselves to strigoi. Gus and Roman rejoin the group, just before the Master and Zach lead a strigoi hoard to assault their hideout. Quinlan forces the Master into the tunnel, along with Zach. Eph steals the detonator and follows them in a separate elevator, sacrificing himself in Fet 's place. The Master fatally injures Quinlan after a vicious battle. Zach, unable to kill his father on The Master 's order, instead shoots The Master. The Master, wounded, attempts to transfer his essence ( the red worm ) to Zach, but Eph tackles him, so the Master possesses him instead. Before the Master can fully take control, Eph arms the detonator and embraces Zach. The Master thinks he has won, but Zach triggers the nuke, destroying himself and, finally, the Master. Five years later, humanity has recovered and destroyed almost all but a few strigoi, who are mindless captive animals without the Master 's control. The nuclear winter is gradually subsiding, and New York City is flourishing. Roman becomes a property developer helping to regenerate the city ; Gus helps resettle refugees in the countryside and hopes to find Ana ; Dutch and other former hackers work to restore the Internet ; and Fet returns to being an exterminator, noticing rats have returned to the sewers now that the strigoi are gone. Fet and Dutch reunite. In voiceover Fet remarks the Master attempted to use love to spread his strain, but love instead proved to be humanity 's salvation.
