Just as Obito had said, Kakashi had actually long since pieced together Obito's identity from various bits of intelligence and details. He simply had never dared to believe—or rather, had been unwilling to believe—that Obito, the village's hero, was the mastermind who had provoked the Nine-Tails Incident, caused the deaths of the Fourth Hokage and his wife along with countless Konoha shinobi, and manipulated Akatsuki to threaten the entire Ninja World!
