I was kinda floored when Kakashi laid out how the Rasengan wasn't even finished, totally changing how I view the Fourth Hokage, and wow, Naruto's got a mountain to climb now. But honestly, Hidan just chilling after getting impaled by those monks was way more unsettling than any training, and it really made me sweat for Asuma; these Akatsuki guys are seriously on another level of terrifying.
