The Blacklist: Liz Keen's history to be revealed!

Answers are coming on The Blacklist.

After faking her death in a bid for normalcy during the season 3 finale, Liz Keen (Megan Boone) was kidnapped by a man claiming to be her father. “We should take him at his word,” EP Jon Bokenkamp tells EW of Alexander Kirk (Ulrich Thomsen), whose introduction provides a wealth of info about Liz’s past, her mother (Lotte Verbeek), and her mysterious connection to Red (James Spader).

"Through the investigation of Alexander Kirk, she finds a lot of her mother’s memorabilia and private journals," Boone says. "A lot is revealed to her about her mother, who she’s known nothing about her whole life, and through her mother, she learns actually a lot more about Reddington."

As The Blacklist inches closer to revealing exactly who Reddington is to Liz, she will discover a shocking truth. “What comes to light is that it’s not really Reddington bringing all of this upon her, it’s her own history and where she comes from,” Boone teases. "Something you start to realize through season 4 is she was strapped with this from birth."

In truth, Boone admits she doesn't even know the real connection between Red and Liz. "I never really felt like it was useful to me to know anything about the relationship that Liz has with Red, or about Red’s history and why he takes such an interest in Liz, because Liz doesn’t really know," she says. "I always wanted to maintain that mystery for myself. That being said, I don’t really know, maybe James Spader, Jon Bokenkamp, and John Eisendrath are really enjoying keeping it a secret from everyone."

Now the question remains: What exactly does Alexander Kirk want from Liz? It won't be long before we find out his true motives as Red, Tom (Ryan Eggold), and the team at the Post Office scramble to save Liz. "It’s very complicated and it’s something that actually gets revealed — it’s a big reveal in episode 3 of season 4," Boone says. "Like a lot of the people that crop up in our show, his agenda is not necessarily altruistic. He doesn’t have the best of intentions."

The Blacklist returns Thursday, Sept. 22 at 10 p.m. ET on NBC.
