Detective Boyle's new romance has upped his swagger, but Jake intervenes before his colleague goes "Full Boyle" and gets too serious, too soon, with his girlfriend. Meanwhile, Rosa and Amy have trouble taking a costumed citizen crime-fighter seriously, and Captain Holt has a new opponent.

The precinct heads to Tactical Village Day, a mandatory training course in which all regional precincts compete. While there, Amy runs into Teddy, a fellow officer she used to date. Meanwhile, Holt becomes addicted to a game on his phone and Rosa is pissed at Charles for not inviting her to his wedding.
