S4E13 · The Audit

Complete story — includes the ending

Captain Holt tells the squad that crime is down sharply in Brooklyn, but everyone's happiness over this news turns to horror when he then says that the NYPD is looking to shut down one precinct out of the 22 in the borough. All of the squads are being audited, and the 9-9's auditor is Amy's ex-boyfriend Teddy, who hasn't forgotten that Amy dumped him with encouragement from Jake. Jake and Amy end up in a comedy of errors in alternately trying to make nice with Teddy and keep him from finding out they still think he's the most boring man alive. At the precinct, Holt tasks Terry to fix a $21,000 Japanese copier that former Captain C.J. ordered, and Boyle and Diaz have to deal with a rat infestation emergency. Gina returns much too early from being badly injured when hit by a bus and uses her status to help fix the 9-9's maintenance issues, while Teddy eventually recuses himself from auditing his ex's squad. The new auditor is a woman who used to date Terry, despises him in the present, and tells him that she's going to shut the 9-9 down for good.
