Starring: Nathan Fillion, Richard T. Jones, Alyssa Diaz, Titus Makin Jr.
Hit and Run - S4-E8
Factual error: Tim says, "At approximately 1057 hours" for the scene, but in the scene, it's shown the time is 10:14. The time should have been said, "0957 hours" for when the suspect attacked Nolan and Harper. (00:13:00 - 00:13:22)
Revelations - S3-E6
Continuity mistake: When Tim puts Lucy in the squad car after "arresting" her, the rear door on the driver side is open, but when the camera pans back to her it's suddenly closed without making a sound.
The Hammer - S6-E2
Nolan: Sorry I had to bail on our wedding reception.
Bailey: You didn't miss much.
The Choice - S5-E4
Trivia: Baily works for LAFD Fire Station 118, the same fire station on the 9-1-1 series; they even use the same engine for both shows.
