Pakkun senses that Sasuke caught up with the Sand as Temari makes the strategical decision to stay and fight Sasuke while Kankuro buys Gaara more time.
Temari's low on chakra from her match with Shikamaru, but holds her own for a while. She uses her fan to send a gushing wind at Sasuke, who wonders if he should just use chidori to finish her off now. He decides to hold out for his fight with Gaara, giving Temari a window of opportunity to attack with Ninpou Kamaitachi (Sickling Winds). Her wind attacks cut through several tree branches and keep Sasuke on the move. She then uses Ninpou Fuusajin! (Dust Wind!) to keep Sasuke pinned to a tree.
Sasuke soon realizes he must do something about her fan and uses Katon Housenka no Jutsu! (Fire Element, Balsam Spread Fire) to shoot fireballs at Temari. She dodges, but he follows with Katon Goukakyuu no Jutsu (Fire Element, Blazing Fireball) and sends a targeted fire stream at her. She counters with Sickling Wind, but as he dodges, he slips on her dust created from Dust Wind and falls. She then hits him with two kunai. Of course, it’s a replacement along with an explosion tag, and Temari is thrown backwards. Sasuke then heads after Kankuro and Gaara.
Meanwhile, Orochimaru reveals his younger body to the Third. Angry, Sarutobi tells him that was the reason he couldn't appoint him Hokage. They then flash back to the past. The Third raids Orochimaru's research facility based on reports that a number of villagers have gone missing recently. They suspect Orochimaru was behind the killings, and learn that he was working on a forbidden technique. Orochimaru's dream was to master all techniques and understand everything in this world. However, that requires a serious time commitment, and even if he was to master everything, that knowledge would eventually die with him. So he started researching how he might achieve immortality to keep his mind in this world forever.
And once Orochimaru kills Sarutobi, nothing will stop him from transferring his mind into Sasuke's body. The First uses a wood technique to fill the dome up with a massive tree, as Sarutobi realizes what a horrible mistake it was to let Orochimaru live back then. As his sensei, he really wanted to believe that Orochimaru would turn out ok, but that night in the lab, when he had summoned Enma and destroyed the research facility, he didn't have the heart to kill him.
Sarutobi vows that he will now correct his past mistake. He uses Shadow Replication and then prepares the Fourth’s Death God technique. The Second uses Genjutsu, Kokuangyou no Jutsu! (Illusionary Technique, Absolute Darkness) and the entire fighting dome goes pitch black. Sarutobi, meanwhile, remembers each of his villagers and gains the strength to do what he must. He will prepare the Fourth's secret technique that even Orochimaru doesn't know - Fuuinjutsu Shiki Fuujin! (Sealing Technique, Demonic Soul Seal).
