Imagine Nick Fury keeping a Nerf gun tapped to the underside of his desk because he knows that Romonoff could start one of her nerf wars at any moment and he wants to have a weapon close at hand just in case.
Nick pulling out the nerf gun when he see’s Melinda reaching towards her leg for something, and the two of them nailing each other in the chest with a nerf dart each and just glaring at each other.
Nick walking down the hallway after a bad day of meetings with bureaucrats, with his nerf gun tucked safely away out of sight, and pulling it out before anyone can see, nailing Jasper in the shoulder and Phil in the forehead with a nerf dart as Natasha, Clint and Melinda manage to book it out of the way and get to safety to collect their own guns. starting a nerf gun war that lasts three hours with work being done in between (not much work, because everyone is too afraid to take their eyes off of doors, windows and air vents for far too long.
Nick walking into his office, only to shut the door quickly when Clint, Jasper and Melinda open fire on him, avoiding all nerf dart and smirking when he hears the three of them booking it out of the office through the air vent and window.
Finding Phil in the cafeteria trying to get coffee while holding up a clipboard to protect himself from anyone who may try to shoot him. Promising him he just wants coffee as well and putting his nerf gun away as he walks over slowly. Once Phil lowers the clipboard he leans in and steals a kiss before shooting him in the stomach with his extra nerf gun and running away as Phil screams at him about being a traitor who’s not getting any cuddles tonight (he knows it’s a lie. Phil will still cuddle him)
