Fracture

S2 E6: Harlee (Jennifer Lopez) and Wozniak (Ray Liotta) investigate Caroline's (Nava's ex fiancée) murder, putting Harlee and Nava's (Gino Anthony Pesi) relationship in an awkward place because she can't reveal her connection to the crime or the methods she will use to solve it. Wozniak focuses on determining which member of his crew is informing to Verco (guest star Dov Davidoff) as Loman (Dayo Okeniyi) uncovers a much deeper secret.
