The Blacklist season 3, episode 20

The third season sees Liz and Reddington on the run from the government and the Task Force. The first part of the season explores The Cabal's efforts to capture Liz and Reddington and their efforts to clear Liz's name. The Cabal is represented by the ruthless Director of the National Clandestine Service Peter Kotsiopulos [David Strathairn]. The season also introduces Susan "Scottie" Hargrave [Famke Janssen], the mother of Tom Keen, Mattias Solomon [Edi Gathegi] and Nez Rowan [Tawny Cypress], key characters for the spin-off series The Blacklist: Redemption, focusing on Tom and Scottie Hargrave. The final episodes of the season also introduce a new series antagonist Alexander Kirk, AKA Konstantin Rostov, who claims to be Liz's father and will stop at nothing to protect her and win her loyalty. An important subplot for the season is Liz's pregnancy and Mr. Kaplan's [Susan Blommaert] efforts to protect Liz and Tom's daughter from Reddington.
