TL;DR – We get a walk down memory lane and a look to the future.
Score – 4 out of 5 stars

Review –
As the season of Brooklyn Nine-Nine continues, we get a blast into the past as the show goes back to the 1990s, which a bit different to last week’s dive into the 1980s. We also continue the theme of interweaving three narratives throughout the story which some work and some don’t quite get there.
So to set the scene, Jake (Andy Samberg) and Gina (Chelsea Peretti) are super excited because it is their 20-year high school reunion time. It was the time of long hair, just one earring, and denim … so much denim. It is also a little bit of a struggle for Jake because his final year of high school was tough as the whole school thought he has tattled on the most popular kid in the school, gaining him the nickname ‘The Tattler.’ But it’s been 20 years surely people will forget, well as they and Amy (Melissa Fumero) arrive one thing is clear, nobody forgets. Now from here, we will be looking at the episode as a whole, so there will be some [SPOILERS] ahead.
