MIGshinobi said: Nagato showed no such ability. He was looking at itachi's right eye and assumed it was amatersau from the bleeding but he was wrong, it was just kotoamatsukami working on itachi. Except that Nagato was behind Itachi and was facing his back when he "sensed" the Koto starting its work. Nagato didn't see Itachi's eye bleed when he first sensed the genjutsu. He specifically says to himself something along the lines of, "The air pressure has suddenly changed!!" and then loudly calls out to Naruto, warning him that Itachi was about to use Amaterasu. It's only later when Itachi turns back to face Nagato and use Amaterasu on him. So no, you're wrong in this one.
