Bonds

is episode 48 of the Naruto: Shippūden anime.

Synopsis
Yamato and his team enter Sai's room to confront Sai, who tells them that not only is he to help in Konoha's destruction, but also to act as a spy against Orochimaru. Yamato reveals that in ANBU Root, one must murder his own comrades and sever their emotions, but Sakura returns Sai's picture book to him, remarking that he still has emotions because he treasures it. After the team ties up Sai, Naruto informs Sai about his brotherly bond with Sasuke and about how far he would go to bring Sasuke, astonishing Sai.

Trivia

 * When Sai goes to look at the book that belonged to his brother, after Sakura asks him "Why do you still treasure that picture book so much?". The image of Sai's brother has blonde hair instead of white hair. This is an error in the animation.
