Talia Bishop comes back to Mid Wilshire to collaborate on a case, and she has an opinion on Lucy's relationship now just like she did during Lucy's rookie year.

She's Sharp. She's stubborn. And she's about to disrupt everything Tim Bradford thought she had under control. Lucy Chen transfers to Mid-Wilshire for a fresh start. Tim Bradford hadn't seen Lucy Chen since her rookie year ended. She's more mature, different. And that intrigues him.

They were supposed to be partners. They were never supposed to fall. They meet as sergeants from opposite ends of the LAPD-two leaders, two reputations, and zero patience for each other. When an undercover operation requires them to pose as a couple, neither is thrilled. Tim Bradford thinks Lucy Chen is too soft; Lucy thinks Tim is all walls and no heart.
