Meanwhile, Naraku is taking back his human heart into his body because he now knows Kikyo's plan to purify him, so he need his heart back not only to stop her, but to recall back his negative feelings toward her in order to kill her.
Kikyo is finished healing Miroku's wounds and tells him to be careful because the more poison he sucks into his wind tunnel, the more his wound will spread, eventually to his heart and he will die if that happens. Miroku looks over at Sango and Kohaku sleeping peacefully and tells Kikyo to keep this a secret, he doesn't want to worry Sango.
