Stone's death sends shockwaves through the precinct, most notably for Sanchez, who can't bring herself to go back to work.
Fitch's ex-wife Linda comes to town with their young son Bobby, who has a lot of questions for his Dad as to why he left New York years ago.
The murder of a teenaged graffiti artist puzzles Longford and Mahajan, but Fitch uses his son for inspiration and leads the duo to the perp.
Meanwhile, Longford still doesn't know whether or not he should retire, and Washington asks Fitch to be the godfather of his child.
