But wasen't the entirely clan destroyed execpt Itachi and Sasuke ? The shark guy who's with Itachi when they are gonna capture Naruto on the hotel, he said something like this, "I heard that the Uchiha clan was destroy by you Itachi." Shouldn't he know if there was somone in akutski that is a sharigan user then ? I bet there isn't someone in the akutski who is a sharigan user otherwise they would know it.
