Goor revealed that the Season Seven finale’s cliffhanger would change the squad’s dynamic for a significant period of time.
However this was scrapped as stated by Goor "We had resolved the big Holt arc for the year… [and] we found out that we had a season eight earlier [than usual], so we didn't feel like we needed [a cliffhanger] to convince the network brass that they've gotta keep us going." 
Vanessa Bayer is the 11th Saturday Night Live alum who's appearing in Brooklyn Nine-Nine.
There is an episode focused on Detective Hitchcock's love life, which Goor describe as "I think people will think it’s funny, hopefully, but not too disturbing".
This season finally reveals whether Kelly is Detective Scully's dog or ex-wife.
While Holt is gone, Terry remained in charge of the precinct, as Goor revealed that "it would be more fun to explore the dynamic of Terry being in charge."
Actor J.K. Simmons appears as a guest star in the ninth episode of this season. He portrays Detective Frank Dillman, a former colleague of Captain Raymond Holt, and the best detective that he has ever known.
