Episode 46 - Unfinished page "Mikan no pēji" (未完の頁)

Naruto finally makes sense of the destruction he witnessed around him earlier. Yamato tells Naruto not to rely on the demon because Naruto is strong enough to withstand the demon's terrible chakra. Sai discovers the loss of his book while resting. Team Kakashi browse Sai's book, and they notice that the book (which can be read from both ends) contains different paths of two boys who meet in the middle. Each page has the boys fighting someone new, each time collecting the opponent's armor and weapons into the next page. The pages where the two boys would meet are unfinished. Orochimaru's group reach their base, not realizing that Yamato's wood clone trailed them there. Sai gets a glimpse of Sasuke's silhouette and eyes and discovers that he is the man Naruto and Sakura are looking for.
