The blacklist season 3
Raymond Reddington (James Spader) and Elizabeth Keen (Megan Boone) in The Blacklist NBC

NBC's hit series The Blacklist is schedule to return on 24 September with season 3, where fans will get to know more about Raymond Reddington (James Spader) and Elizabeth Keen's (Megan Boone) relationship.

Boone has already cautioned viewers that this time around, the crime drama is " going to be a very different show".

In the season 2 finale, we saw Elizabeth Keen aka Liz running away from the FBI along with Red, as her former colleague, Donald Ressler, places her on the FBI's Most Wanted list and removes director Cooper (Harry Lennix) from his position. Liz was being framed for the murder of a United States senator.

In the season finale we also got to know the truth of what actually happened during the night of the fire. It turned out that Liz had shot her father when she was a child to protect her mother, and Red was trying to suppress that memory to protect her.

According to executive producer Jon Bokenkamp, Red is "heartbroken" that Liz remembers the "horrible truth" about her past.

Bokenkamp told The Hollywood Reporter, "Red is heartbroken that, [despite] everything he's tried to do in this season to protect her from this horrible truth, she has discovered it."

In season 3, fans will see Red and Liz living as fugitives and what is ahead for the duo on the show.

"[This storyline] opens and takes us into a new chapter where she is no longer just an FBI agent, they have a real journey that they're about to go on. They're entering the third season as fugitives," Bokenkamp revealed.

With Liz no longer an agent and her former FBI allies now hunting her down, it is safe to say that season 3 will shake things up a bit.

In an interview with Zap2it, Megan Boone said, "Season 3 is going to be the same characters but a different show, a very different dynamic. It is going to change."

She hinted that the changes come from the break-up in the task force, "If you break open the entire task force, then it will be challenging to try to find the procedural aspect of the show again. With 22 episodes a year, it does benefit the show to have some kind of a formula ... but we are going to sort of break open a lot of the structure of the show."

Boone also teased about Red and Liz's relationship and said that Liz loves him, but not in a romantic way.

"I think people see how much Red loves her, and it is a confusing kind of love. I think that will have to be answered. How do you love someone that deeply -- no matter what the circumstances, but especially when the circumstances are mysterious?" Boone said.

"I think she loves him," Boone stressed and added, "But I don't think there are romantic feelings. ... I don't necessarily think it's a [romantic] love story between Liz and Reddington, even though there are people out there that really feel that's what they want."
