Oliver Carter

Jake has a slew of unsolved cases that he can't seem to close, and the other detectives don't want his losing streak to rub off on them. Meanwhile, Holt asks Amy to run lead on the Junior Policeman Program for at-risk youth, and she enlists Rosa and Gina's help. Also, Boyle helps Sergeant Jeffords with a special case he cannot solve.

It's Halloween night, a busy time of the year for any police precinct. Amy detests the holiday, and is not thrilled when she has to don a costume to go undercover on street patrol with Charles. Back at the precinct, Jake bets Captain Holt that he can steal his Medal of Valor before midnight, which results in him bringing out some costumes of his own.
