What Happens? When a murder investigation leads the detectives to the man who shot Beckett in last season’s finale, she is tempted to once again go down the proverbial rabbit hole and lose herself in the conspiracy surrounding the fatal stabbing of her mother. In order to keep her from risking her life, Castle is forced to reveal to Beckett that he has been withholding leads from her as part of a deal for her life that he made with a mysterious Mr. Smith: If Beckett doesn’t investigate her mother’s death, she stays alive. After his pleas for rational thought and honest confessions of love appear to fall on deaf ears, Castle decides to walk away from Beckett once and for all.
Beckett and Esposito go rogue to try to take down the killer on their own, which ends with Beckett hanging off of a rooftop ledge and Ryan coming to her rescue – after he alerted Captain Gates to what she and Esposito were doing. Though Ryan saved their lives, Beckett and Esposito are suspended, but Beckett takes it one step further. She resigns, turning in her badge as she realizes that she has more to live for than simply avenging her mother’s death; that she wants more than the life she had been living up until that moment. This revelation sends her to Castle’s loft, where she tells him that she is ready to move on from her all-consuming quest for justice and become a whole person – with him. As the two of them kiss and prepare embark on the next chapter in their story, we learn that Beckett’s life is in grave danger as her shooter has found Mr. Smith, taking away Beckett’s greatest source of protection and vowing to kill her once and for all.
