Brooklyn Nine-Nine episode five in the second season saw Jake Peralta (Andy Samberg) and Amy Santiago (Melissa Fumero) learn about the secret of their colleagues. In that episode titled 'The Mole', the two were working to find who is the mole in their precinct. They decided to go to his former apartment which Gina (Chelsea Peretti) now owns. Jake has a key so they decided to break-in. However, what welcomed them is a sight they never expected. His best friend Detective Charles Boyle (Joe Lu Trugilo) and Gina are having a sexual affair.
The whole 99 precinct is now aware that Boyle and Gina has a relationship. However, in the upcoming episodes, two more people will know about it. Their parents.
According to Brooklyn Nine-Nine episode spoiler from the Entertainment Weekly, Boyle's very New York Italian father Lynn (Stephen Root) and Gina's 'offbeat' mother Darlene (Sandra Bernhard) will return for another episode.
"Boyle's dad Lynn (Stephen Root) and Gina's mom Darlene (Sandra Bernhard) will be returning in an upcoming episode, where their kids will be shocked to learn they've been seeing each other. Word on the street is that this story will spill over into the New Year, so it's safe to say Gina and Boyle will be tied to one another for the foreseeable future."
Boyle's Dad and Gina's mom will also date each other so that means double the fun. Brooklyn Nine-Nine episodes are set to become more hilarious.
Speaking of double, Brooklyn Nine- Nine episode nine titled Road Trip, will also feature double date with Jake inviting over his new girlfriend Sophia Perez (Eva Longoria) to come with Amy and her boyfriend Teddy (Kyle Bornheimer on a road trip. Amy will be put in an awkward situation as unknown to many, she and her boyfriend are not in good terms, lately. Amy will try to end her time with Teddy but then Jake and Sophia will try everything to prevent that from happening.
