Of course we are going to be continually kept in the dark about those damned bones. I can't imagine their ultimate discovery will be satisfying enough to merit all their attention. This starts off with Elizabeth's usual manic search for Tom's killer. She can't do anything legally because she has no badge but she is seeing a therapist (that woman). In order to keep her under wraps she is assigned a serial killer called The Capricorn Killer. I won't go into graphic details about this guy. Meanwhile, a witness against Tom's killer is brought in but things go sour. Reddington meets the guy but only holds him until he needs him. He has access to those bones. We also have a new example of evil and, of course, Elizabeth, always the lone wolf, hooks up with this person.
