Brooklyn Nine-nine - Season 4- Episode 6

The episode kicks off with a memorable cold open: Charles Boyle’s son, Nikolaj, is terrified of a "monster" in his closet. When Charles goes to investigate, he discovers a disheveled Adrian Pimento hiding inside. After months of being in an Uzbek prison—where he developed some truly disturbing habits—Pimento reunites with Rosa Diaz. The two immediately decide to pick up where they left off and get married the very next day, much to the precinct's shock.
