Pictures exist in this manga.

Naruto's also dumb as shit 80% of the time. He looked at the Hokage Mountain for years and still couldn't deduce that Minato was his father. Gaara was just in total WTF mode. Besides, most of the forces couldn't even make them out, hence the whole "There someone else up there!" He was still coming in view.

Uh, says who?

He's always been using Kamui with MS. Kishi was just hiding the pattern to protect his identity.

Yeah, that must be clearly why I mocked Obito's reasoning earlier. Said it before and I'll say it again, I've been anticipating this to be the reasoning for years now so I've kinda come to terms with it.
