S01E115: Lured by the Black Light

Jakotsu attacks Sesshomaru while Suikotsu kidnaps Rin. However, Suikotsu's good alter ego takes over temporarily as he takes Rin to the village where he tended to children. When villagers ask for Suikotsu to leave, his evil alter ego takes over and kills one of the villagers. Jakotsu then shows up from hiding. Meanwhile, Kikyo and Sesshomaru head off to go after the three despite the barrier on the town.
