Overview The fourth season resolves the question of Alexander Kirk's (Ulrich Thomsen) relationship to Elizabeth Keen (Megan Boone). Kirk discovers that Liz is not his daughter and abandons his obsession with winning her trust and loyalty. Reddington (James Spader) attempts to kill Mr. Kaplan (Susan Blommaert) for her efforts in hiding Liz and her baby from him, but Mr. Kaplan survives the attack and begins exposing the trail of dead bodies left by Reddington’s criminal activities. Mr. Kaplan attempts to dismantle Reddington’s organization. FBI Agent Julian Gale (Enrique Murciano), the former partner of Donald Ressler (Diego Klattenhoff) on the Reddington Task Force, is assigned to the Reddington investigation and Gale tries to use Mr. Kaplan's knowledge to bring down Reddington. The final episodes reveal the existence of a suitcase containing human bones of unknown origins that figure prominently in the next season.
