Complete story — includes the ending
Holt announces the Nine-Nine has a very good chance of being shut down, stating it is between them and the 74th Precinct. Terry learns he needs to work one more case to catch Hitchcock, who has closed the most cases in the history of the 99th, mainly due to being there 20 years longer. Gina continually pranks the detectives while live-casting herself in front of her audience the "Ginazon". Amy convinces Holt to speed through five years of mentorship before the Nine-Nine closes. Jake and Charles set out on their last case together, which balloons into a big drug bust. They go for the bigger collar, even though it means the case will not be resolved until after HQ's decision. The precinct goes to a bar expecting to be shut down, but Holt soon exclaims they are staying open, thanks to the "Ginazon" protesting to the commissioner's office.
