"The Bridge to Peace" (平和への懸け橋, Heiwa e no Kakehashi) is episode 253 of the Naruto: Shippūden anime.
Konan encloses Tobi in a chasm with a large amount of explosive tags that detonates in a wide area. Tobi, however, manages to survive the assault by sacrificing his left eye to use Izanagi, after which he appears behind a shocked and exhausted Konan and stabs her with a metal pipe. Noting that it was a favour to a former comrade, Tobi explains his technique to Konan. Konan refuses to give up and continues to fight Tobi. Tobi manages to subdue her and places Konan inside a genjutsu to force her to reveal the location of the Rinnegan. Tobi travels to the location and retrieves Nagato's corpse and then takes his leave. A blood-soaked piece of paper is blown off Konan's body by the wind and travels to her childhood hideout. As it travels, more of the Ame Orphans past with Jiraiya is revealed, as well as some of their time as the original Akatsuki. Meanwhile, Tobi, dressed in new attire, is told by Zetsu that they have received intel on the Nine-Tails whereabouts from Kisame Hoshigaki. With this, Tobi declares that it's time to capture the Nine-Tails. At the end of the episode, the blood-soaked paper that flew to the hideout covers Konan's frog card, signifying that she was "home".
In Konan's flashback during this episode, Jiraiya used the Rasengan while training with the Ame Orphans. However, given the period that Jiraiya had taught the orphans in, it is unlikely that Minato had created the technique as yet as he would have been a child then or even that Jiraiya had started teaching Minato altogether.
In some scenes, especially when Tobi grabs Konan by the throat, her Akatsuki ring is not appearing on her finger.
The scene where Konan's blood-soaked red paper covered her frog card symbolised the promised they made to return to the cabin to celebrate a job well-done. However, as all four inhabitants died, the cabin symbolised the afterlife and how Konan was the last amongst them to die and had passed to the afterlife to reunited with Jiraiya, Yahiko, and Nagato to celebrate their roles in contributing to peace.
