2x47 - Naruto Shippūden

Sai receives a chilling glare from Sasuke's Sharingan that frightens him. Sai gives Orochimaru a bundle with information about Konoha's ANBU. Yamato gives Sakura and Naruto seeds with his chakra that enables him to track them inside the lair, and reveals that he was able to track Sai because he put a seed in Sai's clothing and food during the visit to the hot springs. Kabuto locks Sai in a room, and the boy summons a bingo book from scrolls he carries. Yamato uses a jutsu to open a tunnel into Orochimaru's hideout, and he, Naruto and Sakura travel to Sai's room undetected.
