SPOILER ALERT: Do not read if you have not yet watched "Dr. Hans Koehler" and "The Corsican," the two-part Season 6 "Blacklist" premiere.
When "The Blacklist" wrapped its deadly fifth season last spring, it did so with the reveal that the real Raymond Reddington is dead, and the man claiming to be him (James Spader) is an impostor. As revealed in two-part Season 6 premiere, "Dr. Hans Koehler" and "The Corsican," that left Red's daughters, Elizabeth Keen (Megan Boone) and the newly introduced character Lillian/Jennifer (Fiona Dourif), in a conspiring tailspin.
While the duo feared for their lives as they investigated "Red" in the first part, by the end of the second part they had executed a secret plan that resulted in one of the world's most wanted men being arrested while buying a pretzel.
Heading into the rest of the season, that arrest continues to affect not only the task force, but also the relationship between Red and Keen, as the former launches an investigation into who turned him in. According to creator and executive producer Jon Bokenkamp, Red in jail is "totally unchartered waters" for both the character and the show.
