Days off are not fun. He doesn't get to go anywhere or fight anyone. He's been forbidden to make his art inside the base. Worst of all, Sasori never wants to pay attention to him. The only good part of these days are pissing off the Zombie Brothers. Actually, even if he didn't have the day off it would be the best part of the day.
He smirks as he sneaks out of the shared bedroom, knowing Hidan and Kakuzu will definitely want to come into their room at some point. Deidara fully intends to be present for that. His eyes flash with amusement at the shouted 'What the fuck, Kakuzu?!' and he counts to twelve before walking around the corner to see what's going on.
Kakuzu looks unamused as ever, but Hidan seems to be freaking out. "Hidan, Zetsu is going to kill you." Deidara peeks into the bedroom from behind them, faced with his handywork. He hadn't thought about Zetsu, but no doubt the plant man will be pissed when he figures out what happened to his roses. Oh well, too late now. Hidan's immortal anyways.
"It wasn't me, Bastard! Why the fuck would I go to all this effort for you anyways?!" Kakuzu just looks at him with that blank expression, but Hidan just seems to get even more heated up. "Fucker, I said it wasn't me! Whatever, suck my fuckin' cock, Kakuzu!" Kakuzu's expression doesn't change, but Hidan goes quiet for a moment, looking almost nervous. "No, I didn't-! Shut up, Kakuzu!" Oh. Oh.
Hidan storms into the bedroom, slamming the door behind him and ranting all the while. He's pretty sure his mouth has dropped open, gaping at the closed door. Kakuzu's head turns, and his heart drops with the smirk that covers the older man's face. The old man doesn't say anything, just enters the room behind his younger partner, but the look on the old man's face as the door shuts almost makes him understand why Hidan wants the man. Ew.
