is episode 252 of the Naruto: Shippūden anime.

Summary
As Tobi is leaving Mountains' Graveyard, Zetsu appears to see him off. Tobi is however stopped by Kabuto who asks him where he was going. Tobi replies that it was none of his concern but tells him that he was going to Amegakure to which Kabuto gives a devious smile after their brief conversation. After Tobi arrives in Amegakure, he is immediately confronted by Konan. Tobi asks her where she has hidden Nagato's corpse and more specifically — the Rinnegan. After a brief exchange of words, Konan and Tobi begin a heated battle on Amegakure's lake. Tobi replies by saying that he will not go easy on her just because she was a former Akatsuki member. Tobi asks what it is about Naruto that made Konan and Nagato defect from Akatsuki, and Konan replies that he is light personified and carries a flower called 'hope'. Tobi tells Konan that he was the one who got Yahiko to found Akatsuki, and the one who gave Nagato the Rinnegan. Konan attacks Tobi in an attempt to kill them both. Konan recalls Yahiko, and Nagato calling each other the bridge to peace, and states that she will be the support to both their bridges. Konan then asks if Tobi understands why she betrayed him. He replies no, and she says it's because he's darkness, and a flower will wilt in darkness. She reveals her ultimate technique and splits the lake beneath them in two.
