Naruto Episode 19
After learning of Haku’s death, Naruto berates Zabuza for his indifference, and Zabuza breaks into tears, conceding defeat. To repent, he kills Gato, despite receiving several fatal wounds in the process. As Zabuza falls, Sasuke awakens, as Haku had not intended to kill him. The bridge is completed, and Team 7 leaves. Tazuna proclaims to the village that the bridge will be called the Great Naruto Bridge to signify the strength that Naruto gave Inari, who in turn gave to the whole town.
