Prompt from Thatgirljess here on fanfiction . net: Could you do a prank war where the whole precinct gets involved?
Three weeks ago, no one would have predicted this outcome. Things had started small, gum that turned your mouth black, whoopie cushions on chairs and the like. There had been pails of water over doors, changed passwords on computers, and sodas shaken up before being offered to the unlucky recipient. The lids on the salt and pepper shakers in the break room had been loosened, the sugar for the coffee was replaced with salt. When Beckett had first found out that Castle, Esposito, and Ryan had been waging a prank war right under her nose she'd been furious with them, but when they'd temporarily joined forces and played one on her by slipping pureed sardines into her milkshake, she couldn't help herself. She fought back. That was when things started getting more elaborate, more devious.
Beckett had put jello powder in the shower heads of the men's locker room so they all got hit with a sticky, cherry flavored spray. Ryan and Esposito had been trapped in the elevator. All the bathroom sink faucets had been covered so they sprayed directly up in the face of whomever was washing their hands. The pranks continued, with more and more people getting involved, until nearly the entire homicide department of the 12th precinct was a part of it in one way or another.
But now the prank war was officially over. And the person who'd won had surprised everyone. Gates had found out about the prank war and called a department meeting for all the detectives that had taken part in the pranking. She'd told them all that she was forced to put them all on suspension without pay for improper conduct. They'd be unable to return until after an official review from the Chief of Detectives. While they were all out, she'd be bringing in some people from other departments to handle their cases. Then she'd sent them all home. It wasn't until the next morning, after they'd all been fretting about the outcome all night, that she revealed via mass text that it'd been a prank and they had all better report to work for their normal shifts - but that there were to be no more pranks.
So, after three weeks of groans, laughs, and retaliation, it was the Captain of the 12th who'd won. And no one but her husband and herself knew that she'd enjoyed every second of her ruse.
