S3E15 The 9-8
The Nine-Nine host the detectives from the Nine-Eight, their neighboring precinct, reuniting Jake with his old partner (guest star Damon Wayans, Jr.). Charles is immediately jealous and tries to reclaim his best friend status with Jake. Meanwhile, the rest of the precinct tries to be welcoming to the Nine-Eight, but it doesn't go as well as they had planned.
