The Two Students

is episode 169 of the Naruto: Shippuden anime.

Synopsis
As Hinata is being healed by Sakura, Naruto defeats the Deva Path with his Rasengan. Naruto pulls the chakra receivers out of the Deva Path's body and uses them to locate the real Pain. Team Guy, wanting to go to Naruto to assist him, are told by Katsuyu that he doesn't want any back up. As Naruto approaches Nagato and Konan, Nagato launches a rod into Naruto, who simply uses the fox's chakra to disturb that of Pain. 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.
