Liz appears to be stunned by the pronouncements of Red about Tom but in the back of her head, she also believes in him. She also knows that sticking with Red may be dangerous for her and Tom but running away from Red will make the situation even more complicated.
Critics believe that “The Blacklist” has held onto the secret regarding the relationship of Red and Liz for a long time and it would give viewers the ultimate satisfaction if such plotline is revealed during the Season 3 finale. They even alluded that it would be shocking if the mystery is carried over by the showrunner and producers in Season 4.
During the 14th episode of “The Blacklist,” Red was shown providing more information on Liz’s mother. His story implied that Liz’s mother walked into the ocean and killed herself.
It would really be a pity for Liz if she feels like she was responsible for the death of both of her parents, especially when she has been struggling with giving up the baby, that she is now carrying in her womb, for adoption.
Red does not want her to give up the baby for adoption but it could be a reason anchored in the past which seems to be connected with the documents that he also needed to find and eventually received.
