The Blacklist Season 5's midseason finale killed off one of the show's major players, Tom Keen (Ryan Eggold). The character's death is set to alter the course of Liz's (Megan Boone) life and have an effect on her and Red's (James Spader) relationship. Moreover, the latest spoiler report indicates that Liz is going to blame Red for Tom Keen's death, which is likely to see the show opening a story arc that focuses on their emotional confrontation.
Liz is unaware of a lot of secrets that Red is aware of, including about the mysterious suitcase full of bones. When she finds out about the secrets, Red is going to emerge as the culprit in her eyes. Executive producer John Eisendrath tells Entertainment Weekly(EW) that Liz is going to find out about the suitcase and why Tom was killed; and once she discovers that her husband died soon after figuring out the identity of the bones' owner, Red will have some explaining to do.
"She [Liz] will learn some truths. Obviously she'll learn about the suitcase. The most important thing she'll learn at some point is that Tom died trying to unpack a secret of Red's. Right there, that is a huge fact that is like an emotional bomb. Once she learns that, Red is going to have some explaining to do."
