The Infiltrator

The infiltrator threads tension through the war prelude as Tobi's spies and the alliance's preparations maneuver in shadow. The episode advances the canon road to war — the Five Kage's alliance solidifying, the threat of infiltration by the enemy's White Zetsu forces emerging, the world organizing against Tobi's Eye of the Moon plan. Security and suspicion shape the mobilization. It's connective canon tissue, the Fourth Great Ninja War's logistics taking shape, the alliance learning that its enemy can wear any face among its own ranks.
