Utterly Unexpected: You have to think of all the details.
Somehow, during the entirety of his little packing spree, Itachi had forgotten about one particular accessory that he never went anywhere without.
Kisame.
Not to say that the man was easy to forget, but the younger mad had, understandably, had other things on his mind. On stepping into the hallway, however, he was abruptly and forcibly reminded that yes, he had a partner, and no, it wasn't really normal for him to be up and around wandering in the middle of the night anymore.
Looking up at his partner, he blinked, the blue man looking back with an expression that clearly asked what he was doing.
"I'm going for a walk."
If anything, that made the confusion on the swordsman's face grow, and he pointedly turned his eyes to Itachi's pack. "Really."
This was going to fail terribly, he was sure of it. Thus, he merely stared up at him instead of responding.
"It's three in the morning Itachi-san." When the smaller figure didn't waver, Kisame had the sudden, intense urge to pinch the bridge of his nose. "It's three in the morning and your cough has been worse lately Itachi-san."
The silence was longer, but Kisame was clearly willing to wait. And wait. After about five minutes, the Sharingan user finally spoke again. "I couldn't sleep?"
"You have all your things." Voice turning dry, one large hand reached out and rested on the smaller man's head. "Let me pack my things and I'll go with you."
"Um. Kisame-san..."
"If I don't go with you you'll drop dead before you get wherever you're going."
"Kisame-san, perhaps it would-"
"I'm going." This time, the hand moved from head to shoulder, and Itachi was steered firmly to a chair in the taller man's room. "Sit. Stay. Maybe you can explain what you're having us do."
"You really don't want me to."
"Of course I do. You're not about to do something royally stupid or anything right?" He had turned to pull on his clothes, but as the silence stretched on, the man slowed to a stop in his movements. "Itachi-san?"
"I'm going back to Konoha."
"...What?"
"I've decided to go home."
"...Why?"
"I feel I've perhaps been a bit lax on taking care of things around the village."
"Itachi-san have you forgotten that you're a missing nin?"
"Well, no. But I have a solution for that."
"And that involved you leaving me behind?"
"Well... no. I just... forgot."
"You forgot."
"Yes."
"You forgot you had a partner?"
"...Not exactly."
"...What exactly did you forget?"
The silence stretched.
"Itachi-san."
This time, the silence was shorter.
"Itachi, spit it out."
"I might have gotten over excited."
"About?"
"...I don't want to say."
"This has to do with your brat of a brother doesn't it."
It wasn't a question, so Itachi didn't bother to answer.
"Wonderful. I'm still going with you."
"I'm leaving Akatsuki."
"Yeah, I gathered that with the talk of going back to Konoha."
"You're loyal to Akatsuki."
"Yes, I am. Your point?"
"...I'm not going to try to catch the nine-tails."
"Yes, I figured that."
"I don't understand."
"Yeah, you never do. Shut up and let me pack."
Completely confused, Itachi fell silent and let the man pack. He'd figure it out eventually.
