Batman tells Ra's that he wouldn't have to inhabit a new body if he could just restore Sam Tang's corpse to its former glory before it was poisoned by the radiation. In order to do that, Ra's would need access to the Fountain of Life within Nanda Parbat - the site of Bruce's rebirth ritual. Bruce offers to show Ra's the way to the hidden city in exchange for letting the boys go. Ra's agrees. The Sensei however has already beaten them there. Seeking to poison the fountain so that Ra's cannot use it, Sensei demands the key to the temple containing the Fountain. The monks refuse and remind the Sensei that the Fountain brings death to those lacking purity of spirit.
