The FBI investigation of Amador's death makes rapid progress when Amador's ring (which he left in the trunk of the car transporting him) turns up at a pawn shop. Stan locates an associate of Gregory's who ditched the car, and is hot on the tail of Gregory himself. The KGB, to cut its losses, frames Gregory for the murder of Amador and offers him exfiltration to Moscow. He refuses and instead proposes to end his life on his own terms, and neither Claudia nor Elizabeth can change his mind. Claudia asks Philip to kill him out of compassion for Elizabeth, but Elizabeth convinces him to agree to Gregory's own plan, which turns out to be a fatal shootout with the police. Meanwhile, Stan promises Nina he will find out who killed Vlad; Stan's wife asks him to quit the FBI and move away with his family; and the Jennings deal with boundary issues in their separate parenting.
