Brooklyn Nine-Nine: “The Oolong Slayer”
(Episode 3.04)

f you’ve felt that Brooklyn Nine-Nine’s third season has underused Amy Santiago and Rosa Diaz, now we know why: They’re too busy passing their juicier cases on to Major Crimes and putting together The Vulture’s social events for him. The former ignominy, at least, is one the entire squad suffers, but “The Oolong Slayer” treats the task of putting together Dean Winters’ birthday bash as a far more soul-crushing disgrace. They’re detectives, and good detectives at that. They aren’t party planners. And yet in “The Oolong Slayer,” their investigative skills are pushed aside at the whim of a narcissistic misogynist, which has the minor benefit of providing an excuse for their lack of involvement in anything more serious than romance plots.
In fairness to Amy, relationship matters made up the core of the season’s first couple of episodes, which gave her plenty to do outside of police work. Rosa, on the other hand, has been practically invisible since the show returned to air last month. Here, she has the chance to exact a little vengeance on The Vulture and bond with Amy, but The Vulture is too much of a dickhead to realize he’s been punked, and we’ve seen Rosa gel with Amy in the past (see: “Windbreaker City” and “Sabotage” from season two). The point made in “The Oolong Slayer” is that they make a good team, even if they’re working on an assignment that falls about a thousand miles outside their job descriptions. That’s great, and maybe we’ll see more Amy/Rosa odd-couple hijinx in the future that match up as well as this week’s for pure hilarity.
In the meantime, the reminder that they can cooperate with one another isn’t really necessary, other than to reinforce the overarching theme of “The Oolong Slayer”’s A-and-B-plots: Good triumphing over evil. Well, maybe not exactly that. Sort of that. It’s more like “good triumphing over stupid,” really, as the ladies thwart The Vulture’s attempt at delegating his self-aggrandizement, while Jake and Captain Holt covertly follow leads on a case involving a serial killer, the titular Oolong slayer. (Apparently, the man has a serious tea fetish, so he leaves a packet of Chinese tea in his victims’ maws and sets up a tableau of creepy dolls having a tea party. If this is meant to be a riff on Hannibal or True Detective, it’s well-played and totally disturbing.)
