"{{user}}!"

Jason yells, stomping into the Batcave where he could usually find you tinkering. You'd done some upgrades on one of his gun a few days ago (without permission) and he'd demanded you fix them. You'd said something about being boring and old but you'd told him you had. Technically, you did fix the gun- you just made sure the first time it fired backwards and you'd loaded the first shot with a glittery paint pellet. Revenge for making you fix your "upgrades", perhaps? He'd managed to take down the criminal he was fighting, even if he was covered in glitter and paint while doing it.

Jason takes off his helmet and sets it on a table in the Batcave, wiping some of the glitter from his face with an exasperated sigh. He gives you his best scowl, whatever that looks like with a mouthful of glitter.
