Naruto Shippuden Episode 47 — Infiltration: The Den Of The Snake!
Published November 28, 2011
Sai is temporarily trapped in a powerful genjutsu from Sasuke's Sharingan, that frightens him. After recovering, Sai tells Sasuke that Naruto sees him as a brother, as told to him by Sakura. Sasuke replies that he has only one brother, the one he is going to kill, and leaves. Orochimaru gives the envelope with information from Danzo about Konoha's ANBU to Kabuto and instructs him to make a bingo book. On reaching near Orochimaru's hideout, Yamato gives Sakura and Naruto wooden seeds to ingest, which are imbued with his chakra, that would enable him to track them down in case they are lost, and reveals that he was able to track Sai with the same seeds that he had secretly fed Sai. In the hideout, Kabuto locks Sai in a room, and the latter summons a bingo book of the same information in the envelope. Outside, Yamato uses a Earth Style Jutsu to open a tunnel into Orochimaru's hideout, and he, Naruto and Sakura travel to Sai's room undetected.
