"Power - Episode 2" (「力-Chikara-」episode2) is episode 291 of the Naruto: Shippūden anime.
The reborn Team Kakashi continues to investigate the recent attack by Kabuto and the reincarnated shinobi when Naruto gets swallowed by a giant snake, but manages to escape using shadow clones, and accidentally ingests snakes that were present in the pond which Kabuto uses to summon Hidan. When Naruto surfaced, Kabuto retreats and leaves with his puppets, using Deidara as diversion, after revealing a village guard corpse in the snake's mouth. Meanwhile, Dokku takes care of the orphans, while Miina, due to trauma, became mute. After the attack, Naruto and Sakura join up with Shiseru, Yamato and Sai going with the rest of the guards. While Yamato and Sai investigate why Kabuto destroyed the village, Sakura and Naruto follow Shiseru to Dokku's house. When Dokku and the orphans see them and seeing Naruto wearing the same forehead protector as the reincarnated shinobi, Leo kicks Naruto and they run until they reach a broken bridge. Leo crosses first and when Dokku and Miina run, they fall down the ravine, but are saved by Naruto. Yamato and Sai ask about information when the nearby village leader showed them a book revealing the origin of The Hole, where the Tonika Village resides. Some power resided on the hole many centuries ago. Naruto dreams again, this time inside his subconscious, in front of the Nine-Tails' cage, showing his feet oozing with the snakes he ingested earlier. Naruto and Dokku talk about Dokku's failure to save a girl in his prime and all his failures in life, unlike Naruto, who became famous even in the Hachō Village, a rural area. Yamato and Sai discuss what will happen next, including "Saezuri" and an institution that will take care of the orphans. Kabuto, along with Hidan and Deidara, converse using scrolls in a graveyard, before putting another talisman in Deidara's head.
Shortly before he attacked Dokku, Hayate Gekkō was not wearing the sheath strapped on his back.
