Gina the PAA is slashed and nearly raped by a vagrant, and James is ready to burn down the precinct to catch the guy. Greg and Diane convince him to be by Gina's side as she is treated for her injuries, and they later bring the creep in. When Greg's low-key approach does not work, Fancy sends in Andy, subtly suggesting he beat a confession out of the creep (who is guilty). Greg and Andy then have a conversation about the use of violence on the job, which does not make Andy feel all that good about himself. Diane remains on a knife's edge in the aftermath of Jimmy Liery's death and her growing estrangement from Bobby, not least after Bobby has a friendly dinner date with Jill Kirkendall. Diane later calls Andy from a diner because she is on the verge of relapsing into alcohol. The main case involves a diamond dealer's sister, who went missing with a large quantity of stones alongside her no-good boyfriend. And Sylvia decides to take an indefinite leave from work to care for baby Theo, leading Andy to say he will do moonlighting to earn extra money.
