The Tenchi Bridge

Yamato disguises himself as Sasori within Hiruko, and goes to meet "the spy" at the Tenchi Bridge. The spy is revealed to be Kabuto, who spills out the location of Orochimaru's current hideout. Before the meeting could finish, Orochimaru appears and interrupts the two. While Kabuto initially seems frightened by Orochimaru's appearance, it turned out to be a ruse as he attacks the disguised Yamato. After telling Kabuto that the figure is not Sasori, Orochimaru recognizes Yamato as one of the test subjects in his experiments to replicate Hashirama's power through blood transfusion of the First Hokage's DNA. Orochimaru also knows that Yamato is not alone as he tells him to call out Naruto, Sakura and Sai from their hiding places.
