"The Two Students" (ふたりの弟子, Futari no Deshi) is episode 169 of the Naruto: Shippūden anime.
Synopsis
As Hinata is being healed by Sakura, Naruto defeats the Deva Path with his Rasengan. Naruto pulls some of the black receivers out of the Deva Path's body and uses them to locate the real Pain. On Naruto's way to Pain and Konan, Shikaku, Inoichi, and a Hyūga clan member confront Naruto, wanting to pursue Pain and try to bring him to justice, but Naruto believes that violence is not the answer for this situation and would only fuel the cycle of hatred more. Upon entering, the real Pain launches a rod into Naruto, who simply uses the fox's chakra to disturb that of Pain. He asks Naruto if he can really find it inside himself to forgive him. An enraged Naruto attacks Pain but stops and tells him he will answer once he hears his story. Naruto then asks why Nagato and Konan are a part of the Akatsuki, and Nagato ends with telling Naruto that they have to go back into his painful past.
