"Oh, get a room, would you?"
Late one evening, in an inn near the border of the Land of Fire and the Land of Rain, Hoshigaki Kisame is writing a mission report while his partner, Uchiha Itachi, rests on the bed on the opposite side of the room. They would have returned to Amegakure by now, had Itachi not needed to rest – the strain of using both Tsukiyomi and Amaterasu in succession in a short period of time was too great. Their failure to capture the host of the Nine Tailed Demon Fox had been disappointing, but running had been their only option. Battling a Sannin unnecessarily was never a wise move, especially when low on chakra. When Kisame reached the part in the report that covered Sasuke's interruption, a though suddenly occurred to him. He glanced over at his partner, who was staring blankly at the ceiling.
"Hey Itachi."
Itachi rolls over onto his side when he hears his partner's voice. His vision swims, and he closes his eyes. His vision without his Sharingan had been slowly deteriorating since acquiring the Mangekyo Sharingan, and now he was nearly blind. So, under normal circumstances, he would rarely deactivate it. But this was not normal circumstances. He opens his eyes again, and stares blandly at his partner.
"What is it Kisame?"
"You never did tell me the details of what happened during the Uchiha massacre. What happened when you came to kill your parents?"
"Well…" Itachi closes his eyes again, and begins to remember.
"So, it's true, then. You've come to betray us." Fugaku frowned as he stared up at the bloodstained katana being held by his eldest son. "What is the meaning of this? You were meant to become the greatest of the Uchiha – not the means of our destruction."
"I am the greatest of the Uchiha, and you are a fool for not realising that, father." Itachi stated without emotion. "I have acquired what you will never have. And now, I am here to kill you. Just like the others."
"You've acquired the Mangekyo Sharingan, haven't you?" A proud look appeared on Fugaku's face. "That's my..."
"Oh, shut up, you fool."
Fugaku fell silent at his son's tone. Mikoto trembled, her eyes flickering fearfully between her son and her husband. Determined to stay strong, she sought out her husband's hand. "Fugaku, if we're going to die, then I want you to kiss me."
Fugaku's eyes immediately softened. "Of course, my dear."
As they leaned in to kiss, Itachi interrupted them, a look of absolute horror and disgust covering his face and their display. "Get a room, you two."
And he quickly slit their throats.
"That would make a great addition to Tsukiyomi." Itachi muttered, "Imagine how Sasuke would react to seeing that over and over again for 72 hours…"
Itachi chuckled softly. Having not said a word of his internal musings, Kisame was baffled. Only one thought occurred to him – perhaps the stories of insanity being inherited along with the Sharingan were true.
