Shikamaru's Genius

Shikamaru's genius takes center stage as he separates Hidan from Kakuzu and leads the immortal into a trap a year in the planning — a forest his clan owns, every tree mapped, every shadow his. The episode is the arc's chess match crystallizing: the lazy strategist, running on Asuma's memory and a stolen pack of cigarettes, engineering a battlefield where an unkillable man can be buried alive. Revenge as a meticulously solved problem. The king Asuma told him to protect drives every calculated move.
