Yamato and the others enter Sai's room to confront him just as Kabuto approaches. Sai reveals to Team Kakashi that his mission involved not only aiding in Konoha's downfall but also acting as a double agent against Orochimaru. Yamato explains the dark truth about "Root," noting that its members were trained to eliminate their emotions by killing their friends, similar to Kirigakure's methods. Sakura hands Sai back his book, pointing out that he must have feelings since he values it. Sai then shares memories of his brother. Ultimately, the team discusses how to handle Sai's betrayal outside the lair, with Naruto expressing his own connections and determination to rescue Sasuke.
