I SUGGEST YOU READ YASHAS UCHIHA THEORY BEFORE THIS. Earliar today i read a thread by Seiko, who talks about how Yamashiro Aoba may be a spy for Akatsuki, he stated How did Aoba know Itachi was back in Leaf so quickly? Which was not truly stated because Gai talked about ANBU reinforcements he called. But when looked back at the anime Aoba also says "And they are after Naruto". This struck me profoundly when i looked back on it, how could he know that they were after naruto, Jirayia knew it and told kakashi, then Asuma, Kurenai, Gai, heard it when Kakashi said it to Itachi, who was shocked that he knew that. After that they took Kakashi to his room and nobody had time to tell anyone else because they were busy contemplating why hadn't Itachi found naruto yet, since its easy to find Naruto in the village. This leads me to my further points. Aoba summoning crows, and all of you who read Yashas theory on the Uchihas may notice about how she explains that The Uchihas derived from crow tengus. REMEMBER THIS: So why is he able to summon crows, it is pretty wierd, the first thing i thought when i saw the crows was that Itachi has come but it was Aoba. I myself believe the crows are symbolic and possibly are a lead, i think the fact that supports him being the third magenkyo user, might be the fact we do not see his eyes ever, but some ignorant people may say hey we do not see Shinos eyes but, we know for a fact that he is from the Aburame clan and uses bugs, also Aoba used a fire jutsu earliar but that goes for many people. It may be that he is working under Itachi, maybe to watch sasuke and naruto. If you remember yashas theory that she states that Itachi might be trying to unlock Sojobo which takes 3 magenkyo sharingan and the kyuubis chakra. But this is all assumption and can not be proved until Kishi does it. I put this in color because people do not seem to read this when they post their comments. I believe the whole correlation of his attributes him having black hair, fire jutsus, his eyes covered, and definitley the crows can lead to suspicion that he might be an Uchiha that is my hypothesis. Also some have stated that the crows seem to be a summoning jutsu but the position he holds is not what most summoning jutsus take, the position he holds reminds me of Zabuzas Hidden Mist Jutsu. It does not seem he has a blood pact with the crows, because once they are hit they dissapear like clones. Well to sum up, the idea of Aoba possibly being an Uchiha might be something you watch for in the future of the manga.
