As The Blacklist heads to Season 9’s finale, Red Reddington (James Spader) is getting more and more desperate to uncover the real mastermind behind the murder of his beloved Liz Keen (Megan Boone), a former FBI Task Force agent and the framing of the longtime unit’s chief Harold Cooper (Harry Lennix).
