"Connecting Thoughts" (繋がる想い, Tsunagaru Omoi) is episode 470 of the Naruto: Shippūden anime.
Kaguya separates Naruto and Sasuke at Black Zetsu's suggestion. Naruto's clone, Obito, Sakura and Kakashi watch Naruto fighting Kaguya. Obito is certain that he can synchronise his Kamui with Kaguya's Space–Time Ninjutsu to retrieve Sasuke. Kaguya notices them, but keeps focused on the real Naruto. Kaguya attacks the real Naruto, who uses Kokuō's chakra to enhance his taijutsu, and the two clash. Kaguya is pressured by Naruto's clones, and opens another rift. Obito syncs with it, and Naruto follows Kaguya through it. Black Zetsu notices Naruto followed them to Kaguya's main dimension. Black Zetsu urges Kaguya to kill Naruto, despite her wish to absorb his chakra. Kaguya strikes Naruto with her bones. Believing to have killed the original, Kaguya returns to her ice dimension. Obito and Sakura appear from Kamui's dimension, intent on finding Sasuke. Kaguya and Black Zetsu are surprised that Naruto's clones are still in the ice dimension. Sakura channels her stored chakra into Obito, who begins looking for Sasuke through Kaguya's dimensions. Black Zetsu determines the original Naruto has Truth-Seeking Balls. Obito and Sakura find Sasuke, who manages to cross the opening created by Obito's Kamui with his Amenotejikara.
