A mysterious prisoner transport plane crashes in New York City on tonight's episode of "The Blacklist," as Red Reddington (James Spader) is re-arrested by the FBI, who have rescinded his deal -- and Liz (Megan Boone) rushes to save him -- despite the fact that he killed her father.
"She says in the standoff with him at the end of the first part of the season finale, 'I don't forgive you. Right now, I want to kill you, but there are answers that I need and I can't get them without you,'" Boone told reporters at a lunch to tease the finale of "The Blacklist" at Cecconi's in West Hollywood.
So, as much as Liz wants to walk away from this one-sided relationship with Reddington, who holds all the cards, she knows she is stuck with him.
"That is the nature of their relationship now," she says. "There is tension. They are very opposite. They have different agendas, but they rely on each other to get those agendas through."
One such agenda is discovering the identity of Berlin, their greatest enemy to date, as he has not only masterminded the plot against Red, but is also the person who planted Tom (Ryan Eggold) in Liz's life.
"Tom has already said, 'I am accountable to Berlin.' He has information about Berlin that we don't have. There is something very, very surprising about Tom's involvement in the finale."
As law enforcement scrambles to recapture all the prisoners who were on the crashed plane, it quickly becomes evident that every member of the task force's life is in jeopardy, not just Liz's -- and Red may know why.
"He still has answers they need to stop a major catastrophe, and that major catastrophe is Berlin," Boone says. "In their mind, he has information about Berlin that they need in order to stop civilian casualties and a huge catastrophe in New York City. He still has leverage."
As Liz tries to get Red out of custody, Tom may interfere with her plans as he holds Liz and Red at gunpoint. But Liz isn't the same woman she was at the beginning of the season, so her response may not be what Tom expects from his estranged wife.
"You see these different colors of her being darker and more jaded," Boone says. "In the beginning, she was very naïve. She had the wool pulled over her eyes… These new challenges have introduced to her a truth about life and the dark underbelly of the world that she never knew existed. I think she had an inkling but she was always turning away from that inkling. Now, she is head-on, full force involved in the dark side of things."
Boone promises a lot of questions will be answered in the finale -- which ones she won't reveal -- but at the same time, a lot of new questions will be posed.
"What I really like about the finale is it leaves you in a place where you get a sense of where we're going for Season 2, and it's exciting," says Boone, who calls it a "full-blown thriller." "It's a new direction. I thought the writers did a great job with teeing us up for a really successful second season. "
The "Berlin: Conclusion" episode airs tonight at 10 p.m. ET/PT on NBC.
