Do memories lie? For The Blacklist's Liz Keen, they just might.

Liz, or Masha, spent the last three seasons digging into her past. What she found - sorry, what Red told her - was that both of her parents died years ago, her father by her own hand. Now that Alexander Kirk has revealed himself as the protagonist's long-lost dad, Liz will have to sift the truth from the lies as season 4 begins.

"I don't know why we wouldn't believe him. Red's said before that he's not Liz's father. This man shows up in her life and says he's her father. Liz should take him at his word," executive producer Jon Bokenkamp informed Entertainment Weekly. "She thought she shot her father. It raises a number of questions, which is going to be the joy of season 4."

Don't worry; The Blacklist writers are planning on untangling this addition to the series' complicated web of a plot. We know Kirk located his daughter when the media released her Russia name during last year's manhunt, and it would stand to reason that the newbie will help fill in a few of the other blanks.

"All of the things that you would point to and add up on one side of the ledger that might discount this guy's story about his being her father, we are responsible for next year and in years to come to incorporate it into the story that we've already told," John Eisendrath explained.

We do know on thing for sure - as Liz focuses on figuring out her complicated family, viewers will start to learn how exactly she is connected to Red.

"What I do promise is that Alexander Kirk and his relationship to Liz will ultimately give us a far deeper understanding of Red's relationship to Liz in season 4," Bokenkamp teased.
