"Sakura's Tears" (サクラの涙, Sakura no Namida) is episode 43 of the Naruto: Shippūden anime.
Kabuto states that Naruto's current form is a consequence of his desperation to bring back Sasuke to Konoha. Sakura begins to cry and tries to approach Naruto, but is attacked by him. Yamato erects chakra-suppressing wooden pillars to bind Naruto before he does any more harm. Kabuto heals Sakura and disappears after reasoning that Konoha are not Orochimaru's enemies because they are also fighting Akatsuki. Yamato forcibly returns Naruto to his normal state. Meanwhile, Sai, who was hiding nearby the battlefield the entire time, confronts Orochimaru on behalf of orders from Danzō.
