Philip and Elizabeth tell the kids that they are going to live apart for a while—they don't take it well. Meanwhile, Gaad plans to assassinate Arkady, the new KGB resident, on his regular jogging route. Philip spends the night with Martha, and the next morning Amador confronts him. They fight and Amador is stabbed; Philip takes him to a deserted building where he and Elizabeth attempt to treat him and question him about the FBI's plans. At the time of Arkady's regular jog, the FBI find only his assistant Vlad, as Arkady is fortuitously injured. On Stan's unauthorized initiative, the FBI seize Vlad and take him to the safe house. Stan phones Arkady and threatens to kill Vlad unless Amador is released. Amador dies in the Jennings' custody and they dump the body; after he is found, Stan returns to the safe house and kills Vlad.
