With Liz getting pregnant with Tom Keen's baby girl, and Liz deciding to tie the knot with Tom, things will definitely get more exciting in "The Blacklist" season 4.

Liz and Tom crossed paths in "The Blacklist" season 1, when Tom played the role of her fake husband and eventually fell in love with her. In season 3, a pregnant Liz decided to marry Tom, who once married her with his clandestine motive. This leads to one of the biggest questions for season 4.  

According to Ryan Eggold who plays Tom, his character will play a significant part in the first few episodes of the upcoming installment. As season 4 premieres, viewers will discover what happens between Tom and Liz and the baby girl that they share.

"We're going to deal with that in the beginning of season 4 and then make our way to a brand new series," Eggold told TV Line.

It was also revealed by series creator Jon Bokenkamp that Red is the one who will try to know what happened to Liz following the kidnapping incident. The final episode of season 3 saw Liz get kidnapped by Alexander Kirk who claimed to be Constantine Rostova, her father.

Meanwhile, executive producer John Eisendrath also revealed that season 4 intends to tell stories about Liz and Tom where they are struggling with parenting and identity issues that might break them apart. According to him, "The Blacklist" season 4 will not be a domestic drama so viewers should not expect a perfect household for Liz, Tom and their baby.

"We intend to have a lot of fun with the complexity of the situation that they are confronted with," he told Entertainment Weekly.

The new season of "The Blacklist" premieres on NBC this fall.
