The war between international crime boss-slash-FBI asset Raymond “Red” Reddington (James Spader) and Mr. Kaplan (Susan Blommaert), his longtime crime-scene cleaner (whom he tried to execute earlier this season), goes DEFCON 1 in The Blacklist’s Season 4 ender.
When Mr. Kaplan—she took on the name as a tribute to her murdered lover— helped FBI agent Elizabeth Keen (Megan Boone) fake her death last year to get away from the danger that Red exposed her to, “she knew that Red would consider it a betrayal,” Blommaert says. “Mr. Kaplan wasn’t surprised when he shot her.” In retaliation, Red’s former friend (and Liz’s childhood nanny) covertly attacked his global businesses and nearly fatally poisoned him. “She knows exactly how he built his empire and exactly how to unravel it,” the actress notes.
