Plot summary
Flashbacks depict Eph and Nora's first meeting at a medical conference and the beginning of their romantic relationship. In the present day, Zach's grandparents have been located in Georgia and Eph and Nora make plans to take him there. Eph confesses he still loves Nora, but she is unresponsive and walks away. Dutch ends her relationship with Fet, choosing to reconcile with Nikki; however, Nikki is leaving the city, saying that Dutch has found her true passion in fighting the strigoi and she cannot take part in that. Gus and Angel break Gus's former fellow-inmates out of Rikers Island prison and recruit them as soldiers for Quinlan.
Setrakian meets with Alonso Creem, who schedules a final auction for the Occido Lumen between Setrakian and Palmer. Quinlan tells Setrakian the Ancients will agree to financially back him to obtain the book. In return, Setrakian must hand over the Lumen to the Ancients after he examines it. Eichhorst demands that Palmer give him unlimited financial control at the auction. When Palmer balks, Eichhorst reveals that Palmer will soon die without another dose of the Master's rejuvenating white essence, and Palmer grudgingly accedes. A furious Mayor Lyle threatens to indict Feraldo for extorting money from the Upper East Side's wealthy residents; however, he is killed under suspicious circumstances, making Feraldo a potential suspect.
In the aftermath, Palmer offers Feraldo his political support, and the New York city council appoints her as the city's new special director of security. Feraldo vows to combat the strigoi menace by any means necessary, and agrees to help Eph and Nora mass-produce their anti-strigoi bioweapon. Quinlan orders Gus to kill Setrakian and take the Lumen if Setrakian refuses to surrender it to the Ancients.
