Liz Slighted By Red On 'The Blacklist', 'Sibling Rivalry' With New Agent

Could Liz Keen (Megan Boone) ever call Red (James Spader) 'Dad'? The master criminal denied any paternal connection to his coworker last year, but executive producer John Eisendrath knows that there is much more to the story.

"I think that hopefully we have a few tricks up our sleeves this year that will keep the debate going," Eisendrath explained to Buddy TV. "And the trick is to keep the debate going while letting the characters be honest. It can't just be Red crassly manipulating Liz's feelings about who her father is because that would be hateful.

"I do think that this year part of the season will be about Liz trying to wrestle with the emotional weight of, "If the devil is my father, what does that make me? Who am I? Am I someone who is destined to be the devil's disciple? Am I more bad than good?" Eisendrath said, according to Buddy TV.
