Having rescued Alex, nearly bleeding to death, but failed to catch mole FBI agent Jason Faber, the O'Connor parents fear they must run and pick up brat Sarah, who reacts must ingrate after Mark saves her from a Russian killer by fatal knife in the concert hall where she had singing practice. Viktor and Natalia's cabin happiness proves short-lived as they barely survive a Russian attack and decide to return and help the family. Alex puts stopping Black dagger first and risks everything to face Sam and convince him he was set up, which convinces but suffices not to stop the official manhunt or to bring down the mole, who meanwhile warns the Resident to cover their tracks ruthlessly. Operator Oscar Christoph meanwhile has a single Achilles heal: his new York lover, idealistic Elizabeth Simpson who belies him an idealistic UK reporter.
