Obito opened his eyes groggily, rubbing his temples, the memories of, well, everything, returning to him quickly, making him wonder how Naruto would stand dispelling so many shadow clones, that would be a jutsu he would avoid at all costs. He looked around his dark room and realised that he was at the Akatsuki base, fucking perfect, that meant he had to act as 'Tobi' and damn that was annoying. Plus, he didn't know how he'd act around Itachi, the man was smart, smart enough to fool him the first time around, not that he'd tell anyone. But he could be useful.

The best thing to do right now would be to open the scroll that Naruto had given him and read it to see what his cover story would be when he returned to Konoha and so that he could see if he would be able to show it to Itachi to get the man on his side. He honestly had no idea what Naruto, the Hokage, would put in a note to another Hokage explaining why a man who had been 'dead' for years and was now a missing nin was now in his village and manage to convince him to let Obito stay in Konoha.

Hokage-sama,
I am writing this to you to explain the presence of the ninja in front of you, as you may or may not already know he is Obito Uchiha. During the mission to Kanabe Bridge he was, in fact, crushed by rocks, and near dead when his teammates left, they couldn't have known that he was still alive. But he was. Madara Uchiha's henchman (who is actually controlling him) found Obito and took him to Madara, whom - wanting someone to train and work for him - healed Obito using his artificial henchman's cells, since they were Hashirama Senju's. He then continued to train and manipulate Obito for years but the boy never turned to Madara's side, when he was allowed back to Konoha, it was set up so that he saw Rin Nohara's death, which made him lose himself and fall into Madara's promises. Recently that changed when he met me, and now he would like to return to Konoha. I will vouch for him, as will the Nara clan.
The Rokudaime Hokage

Wow, that boy was talented at what he did, no wonder he made Hokage, despite being so young. It probably wouldn't help Obito with Itachi though. He sighed and stood up, thinking he'd have to do it himself, but then another two scrolls slipped out of his pocket, one saying 'Itachi' on it and the other saying 'Nagato' - so the boy had been prepared after all. He chuckled and decided that Itachi would be his first call of business, so read it too.

Itachi Uchiha
Now, this might all seem very strange to you as, no matter how much of a genius you are, this is odd. 'Tobi', as you know him, is actually Obito Uchiha, the ex-teammate of your ex-anbu captain Kakashi Hatake, who is currently the jonin sensei on your adorable little brothers genin team. Sasuke is fine, by the way. Anyway, Obito was manipulated by Madara Uchiha, whom you should know of but isn't as dead as you might think, and now wants to change his actions, however, Zetsu is Madara's henchman and the one pulling ALL of the strings, so we need your help. Obito has been tasked with getting rid of the Akatsuki - my comrade would apreciate it is Hidan was left alive so that he can kill him himself - while protecting you and trying to get Nagato and Konan to our side. He has another scroll for this. You're brother is being targeted by Orochimaru, though the snake has yet to do anything, so any help you could offer on that front would be much appreciated. Please return to Konoha with Obito as Sasuke needs you. I hope that this explains a lot.
The Rokudaime Hokage / Sasuke's best friend (the one you told him to kill - no hard feelings?)

Still laughing from the last comment, Obito rolled the scrolls back up and decided to head out - minus his Zetsu mask, opting for his normal mask instead, if Zetsu asked he'd say that he wanted some 'private time' and then forgot to switch. After all, it wouldn't do for Zetsu to find out about his betrayal, even if he couldn't do anything yet, not without the Juubi.

Obito stood up, mask firmly in place and cloak covering all excess skin, before walking calmly to the door, trying not to freak out. How the hell had he thought that he would control a group of missing nin (only the strongest) in the past, he had no idea. Madara must've been feeding him drugs or something. But he did manage to open the door, eventually, handle feeling hot and slippery to touch, even through his gloves. Why had he been so desperate to cover up? Oh, right, scars. Yippee.

Forcing himself to skip as he walked, Obito made his way down the corridor, only stopping when he saw the other Uchiha walking with Kisame. Damn, had Itachi (one of the scariest people he knew) always been that young looking? Damn. "Itachi-san, Kisame-san!" Obito said in a sickly sweet 'Tobi' voice, "Can Tobi," referring to himself in third person- he was going to puke, "Borrow Itachi-sempai for a minute? Tobi's a good boy!" He was seriously going to puke. Or kill himself. Or kill someone else. He liked that last option. Particularly killing Zetsu.

Itachi was blinking dumbly, which Obito took as a good sign, before he finally responded with, "Hn, Kisame." Of course, Obito hadn't been around Itachi for a while, so was nervous. For all he knew, that could mean kisame, let's go or Kisame, kill him. Well, he was Obito Uchiha, so he could fight both of them off fairly easily but still, as he couldn't HURT Itachi, that would be a problem.

Luckily, Kisame soon started walking off, so Obito knew that 'hn, Kisame' had meant you can leave, most of the Akatsuki members thought that he was weak or an idiot anyway, so they would underestimate him. "Thanks, Itachi-senpai! Can we go somewhere quieter?" Itachi nodded, obviously not knowing what this was about - no one would naturally assume that THIS could happen anyway.

Obito lead them through several hall ways until he reached the one room that he knew Zetsu wasn't watching and wouldn't watch. The bathroom. Itachi looked a little bit disgusted and took a tiny step back, Obito almost snorted. "What is going on, Tobi?" Aww, Itachi sounded just like his brother, but, you know, less crazy evil psychopath who ran away with Orochimaru and then wanted to be Hokage. Cute.

"Don't worry," Obito giggled, as would his persona, "I'm not going to just you or anything, Tobi's a good boy!" Itachi took a cautious step forward, letting the door swing shut behind them, "Can you lock the door please, senpai? I need to tell you a secret, Tobi's a good boy!" God, he was having a hard time sounding so fucking excited all the time, if someone were writing this there would be a shitload of exclamation marks.

"Hn." Is that all Uchiha's did? Nope, 'cause he was an Uchiha. He almost grinned at that. No wonder his clan had hated him. But seriously, what was up with all the 'hn's, what does 'hn' even mean? The sound of the door locking drew Obito from his thoughts, "So, what did you want to tell me, Tobi?"

Obito couldn't resist, Honest to God. Or Kami. Or whatever. He couldn't, "I like you, Itachi-senpai, and I locked you in here to rape you!" Itachi paled and stood in shock, mouth gaping. Obito burst out laughing, "Oh shit, your fucking face, oh God." he could hardly breath, Itachi, however, seemed to be getting that it was a joke and was glaring (but the pink blush on his cheeks did nothing to help him show his anger). "Sorry, sorry, couldn't resist," he was wheezing now, great. He really needed to work out more. "But seriously, read this." He handed Itachi the scroll, glad that his sharingan was always on to capture this moment.

"Naruto." That name made Obito sober up fast as he pinned the Uchiha with a glare (using his mangekyo sharingan, that was always effective), making the younger back up against the wall slightly as Obito growled and started cornering him.

"How the FUCK do you know that's Naruto-sama just from the scroll he wrote?!" Obito was pissed, and maybe it wasn't wise to call him 'Naruto-sama' in front of Itachi, but hell, he was mad. Had Itachi been stalking Naruto? Hurt him? The note did say that Itachi had instructed Sasuke to kill him after all. "I swear if you've so much as fucking touched him, I'll kill you. And if you're a God Damned stalker I'll rip of your-"

Itachi held his hands up in surrender, "I recognised Uzumaki-kun's writing because first of all I used to guard him when I was in anbu, and second of all I was the one who taught him to write." Obito froze, taking the information in, "We were friends and I asked him to try to befriend Sasuke, so I hoped that it was him. Now I know that I was correct." Who knew that another, non-evil, Uchiha could talk so much. "How do YOU know Uzumaki-kun?"

Obito smiled, "He told you, didn't he? He saved me from myself, well, myself and Madara Uchiha and Kaguya, so, you helping or what? 'Cause Uzumaki has a lot of faith in you, oh, and I'm just gonna say this once, so you can believe me or not but you aren't to tell anyone," his language was bad when he was pissed, he realised. Normally he was so posh- well, he thought that he was. "We are from the future and in the future your stupid Otouto stabs Naruto in the heart with a chidori and betrays him and then tries to take his position as Hokage."

Itachi gaped, in shock again, and Obito grinned, "Look, Uchiha-chan," Itachi glared, "We can't act any more civil than normal, or any different, however, we do have to try to achieve Naruto-sama's goals, to make you happy, I die for Naruto in the future. So we can be friends. Sort of. Anyway, let's continue to kick buts together, senpai!" Obito knew it was over so slipped into his 'Tobi' facade, again. Itachi nodding, now knowing it was time to leave. And if anyone saw them leave the bathroom together, no one commented. Much. To their face.
