Plot
Jake and Rosa are following a bank robber, Billy Ocampo 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, 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 that 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 she wanted to work on a task force led by a woman, that he decides 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 accidentally loses Amy's pen, which she considers crucial. 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 and Scully fight over Scully's new girlfriend interfering in their friendship. Terry and Boyle try to help them, to no success. Eventually, Gina manages to reconcile them, by treating them "like animals".
