Brooklyn Nine-Nine “The Mole” Recap: Andy Samberg’s Jake Peralta, Andre Braugher’s Captain Raymond Holt Hunt For A Spy In Their Precinct [VIDEO]

The Brooklyn Nine-Nine crew was off last week, but fear not! The FOX hit series came back tonight to deliver a hysterical hunt in "The Mole." Aimed at finding a leak within the Nine-Nine precinct, tonight's episode also made another stunning revelation: Gina (Chelsea Peretti) and Charles Boyle (Joe Lo Truglo) are STILL "casual lovers!"

Kicking off the episode, we find Captain Raymond Holt (Andre Braugher) at Jake Peralta's (Andy Samberg) desk while Agent Miller from Internal Affairs investigates his office. Holt reveals that there is a mole within the Nine-Nine crew, but Peralta finds it hard to believe. Holt, on the other hand, finds his belief that no one could turn to be ignorant.

During a brief meeting with Miller – who is an immense germaphobe – Peralta admits that he has never taken material out of the precinct. One catch... he has! Peralta then admits this to Amy Santiago (Melissa Fumero). Together, the duo head to Peralta's apartment – in Amy's new ride, by the way – to get the files.

Jumping to Holt, Deputy Chief Madeline Wuntch (Kyra Sedgwick) enters and finds immense pleasure in the fact that the former is going down burning. She then pokes fun at the fact that Rosa Diaz (Stephanie Beatriz) and Detective Terry Jeffords' (Terry Crews) "Giggle Pig" taskforce drug case has gone nowhere. Holt inquires, pressuring the two to make some headway. Luckily, they have a plan to catch some sellers a silent disco.

Meanwhile, after grabbing the files at his apartment, Jake tells Amy he left some other ones at his old apartment... which happens to be Gina's. Together, they head there... but not before ruining the interior of Amy's car with powdered donuts, of course.

When entering Gina's apartment (with the key he kept), Jake and Amy find Gina and Charles in the middle of their love-making. Needless to say, they're stunned. Jake, however, is more so mad that Charles lied to him.

At the silent disco, Rosa acts as a disco-goer while Terry plays the role of bartender. He's approached by a young girl who, when asked about "Giggle," claims she doesn't do it. She does, however, have a t-shirt of the same pre-school Terry's daughters are currently attending. Later on, they discover that while she's not doing the drugs... she is selling them! Which causes Terry to fear for his daughters' futures.

During a brief discussion of being caught in the act, Gina decides hers and Charles' casual fling is over. They must make sure word doesn't get out.

While putting the old files back in the cabinets at the Nine-Nine precinct, Peralta is discovered by Miller and threatened with suspension. Jake then heads to Holt's house in the wee hours of the night, telling Holt everything. Yet it seems the RJH on his pajamas has Peralta more interested, mainly because he is unaware of the Captain's middle name.

In the end, Peralta demands he and Holt find the mole. When questioned about why he's suddenly adamant that there is a mole, Jake admits that he's starting to think he doesn't know everyone as well as he thought... which causes Holt to figure out Charles and Gina are sleeping together (through some crazy steps that can only be understood by watching the clip!).

Gina, meanwhile, meets Santiago at a bar to get some dirt on her to use against her should Amy tell the squad about what she and Jake saw.

Later that night, we find Jake and Holt in pajamas (Jake in the guest PJs), staying up all night and trying to find the mole. Their "sleep over" ends with the two accusing each other of being the mole.

The next morning, Peralta confronts Holt and proposes that Miller is actually the mole, working for Wuntch. The thought sounds feasible to Holt, because he noticed Wuntch immediately knew to nod to Miller and not attempt to shake his hand, having already known he was a germaphobe. How? Because she told him to investigate the squad!

After giving Miller a thumb drive that supposedly had information about Captain Holt, Jake – with the Captain by his side – catches Wuntch and Miller watching it at a nearby restaurant. Which causes Holt to throw down the brilliant, "You're Wuntch meat," line. Looks like Wuntch won't be a problem to Holt anymore! Could this be a goodbye to Kyra Sedgwick?

After digging around, finding out the seller's actual name, Terry declares that he and Rosa could have more leads for the Giggle Pig case. He also apologizes to her for letting his personal life interfere with work. Rosa calms him, telling him his daughters will be just fine because he's the best dad she knows.

At the end of the episode, Amy eases Gina's worries and tells her she won't tell anyone. Gina, however, announces to the entire office that she and Charles are sleeping together –– claiming she's going to "Olivia Pope this sitch!" And surprisingly enough, she doesn't regret it!

Jake and Charles make amends, and Holt reveals to Peralta his middle name –– JACOB!
