Jake sighed as he pushed open the gate of the bullpen and surveyed the motley crew of his workmates. He had spent the last two days following a lead that took him out of town and after spending the night in a crappy motel, he had discovered his lead had been a dud.

Jake was tired and annoyed. He needed the chipper and somewhat annoying presence of Amy to lighten his mood, she always did. His eyes automatically fell towards her desk but it was empty of paperwork and empty of her. Jake sighed and then checked to make sure that no one around was watching him. Charles bounded up to him like a puppy and began yapping at him, his arms waving wildly. Jake was tired and tuned him out while he moved towards his desk.

Jake smiled at Charles and nodded, ignoring most of what Boyle was excitedly saying, while noticing that Rosa too was missing from her desk.

"…undercover assignment…"Charles rambled and Jake put his bag down heavily spinning around.

"Santiago and Diaz?" Jake asked, and Charles nodded, his eyes wide, face plastered with a grin. Jake wished he had been paying more attention. Boyle seemed like was waiting for Jake to say something in response.

"Peralta!" Called Holt from his office and Jake pushed Charles to the side as he strode into the office.

"Morning Cap'n. Whuddup?"

Captain Holt paused and raised an eyebrow but said nothing about the greeting.

"I will assume that Detective Boyle has already briefed you on the whereabouts of Detectives Diaz and Santiago." Jake nodded slowly, he knew they were undercover.

"I must say-" Holt continued. "You are taking this assignment much better than I thought you would have. Very mature. I commend you."

Jake turned slightly to see Charles waving frantically from his desk and miming taking off his shirt. Jake tried to wave Boyle away and turned back to the captain and grinned.

"Mature is my middle name."

It appeared as though a smirk passed across the Captains face but it was gone before Jake could be sure. Holt handed him a manila folder across the table.

"You will be meeting Detective Santiago at 10pm at the address provided. You will use the money in that envelope to purchase her time, to maintain her cover and she will give you the intel she has gathered thus far."

"Jaaaaaakkkeeee." Came a whisper and Jake turned to see Boyle's face at the door frame, eyes wide, mouthing something and frantically miming taking his shirt off again.

"What are you even doing?" Jack mouthed back and turned his attention back to Holt who had been watching Boyle with a neutral look on his face.

A small smile twitched at Holts lips as he turned his head towards Jake and spoke. "I will assume then, that you are infact not aware of the location, or the details of this assignment." Jake frantically flicked through the pages of paper in the folder, a smile plastered on his face, but nothing jumped out at him. He shook his head.

Holt's phone rang and he took the call.

Jake continued to search the folder and when he turned the last page he saw two full length body shots of Amy and Rosa. Underneath each photo as per usual, was an Alias.

Rosa Diaz AKA Jasmine

Amy Santiago AKA Caramel

"Caramel?" Jake mouthed to Holt who was still on the phone and turned in his chair to avoid Jake.

Jake thought about the evidence, trying to deduce where his co-workers were. He knew he had to buy time to see Amy, and that their names sounded suspiciously like….

Suddenly something in Jake's head clicked and he whipped his phone from his pocket, googling the address provided for the meet. He turned as if in slow motion and even as the search results flashed on his phone, Boyle's weird actions started to make sense and Jake knew exactly where Rosa and Amy where even before he looked down at his phone to see the name 'Mermaid's Strip Club'.

Jakes mouth fell open.
