Plot
Jake (Andy Samberg) and Rosa (Stephanie Beatriz) are following a bank robber, Billy Ocampo (Dutch Johnson) in a warehouse. They try to catch him and his men but Ocampo escapes. The rest of the henchmen turn out to be undercover officers working for Lieutenant Melanie Hawkins (Gina Gershon), who is angry with them for messing the operation.

Jake and Rosa apologize to Hawkins for the mishandling but she is impressed by their abilities and she offers one of them a place in her task force, The Slaughterhouse. Despite agreeing not to compete, Jake and Rosa eventually turn against each other and try to catch Ocampo by any means, even sabotaging each other. Eventually, they find Ocampo in a building and Jake arrests him. Jake intends to get credit but Rosa tells him that she wanted to work on a task force led by a woman for once, making Jake decide to give her the credit. Hawkins is impressed by their loyalty and allows both to enter her task force. However, Jake overhears Hawkins talking with Ocampo, finding that she is a collaborator with him.

Meanwhile, Holt (Andre Braugher) accidentally loses Amy's (Melissa Fumero) pen, which she considers very precious. When she does not seem to be bothered by it, he decides to help her express her anger when confronted. After failed attempts, she manages to let her feelings out regarding the pen, pleasing Holt. Also, Hitchcock (Dirk Blocker) and Scully (Joel McKinnon Miller) fight over Scully's new girlfriend interfering in their friendship. Terry (Terry Crews) and Boyle (Joe Lo Truglio) try to help them, to no success. Eventually, Gina (Chelsea Peretti) manages to reconcile them, by treating them "like animals".

Critical reviews
"The Slaughterhouse" received mostly positive reviews from critics. LaToya Ferguson of The A.V. Club gave the episode a "B+" grade and wrote, "I don't want to say Brooklyn Nine-Nine so much telegraphs its dirty cop reveal with Hawkins... But general sitcom and television tropes do. Besides the unlimited supply of leather jacket ensembles in The Slaughterhouse, the general grizzled 'super cop' concept lends itself to revealing an untrustworthy character. Brooklyn Nine-Nine already subverted that particular expectation in 'Det. Dave Majors,' so it was overdue with Lieutenant Hawkins, unfortunately. Still, the contrast of the bright and cheery Nine-Nine world with the grittiness of The Slaughterhouse and all its nameless team members work for this episode, and Jake and Rosa make perfect sense as the two detectives with the biggest aspirations to enter this world (going into the end of the season)."

Alan Sepinwall of Uproxx wrote, "'The Slaughterhouse,' meanwhile, introduced Gina Gershon as legendary NYPD badass Melanie Hawkins, who would appear to be this year's final big bad. Having Jake and/or Rosa join her squad full-time might have been a status quo shakeup too many in a season that's had a lot of them, especially since we know everyone will eventually wind up back at the Nine-Nine, but having their competition turn out to be moot because Hawkins is dirty and needs to be taken down neatly sidesteps that problem." Alexis Gunderson of Paste gave the episode a 8.4 and wrote, "Seeing how firmly they have each other's back when decision time comes, that gives hope for the last two Season Four episodes next week, which, if the cliffhanger in 'The Slaughterhouse' is any indication, will actually make sense as a doubleheader."
