ander is not satisfied living in the basement of his parent's house and is looking for an apartment of his own to live with Anya. Meanwhile, a demon called Toth chases Buffy at the Magic Box, and his smell guides Giles to the city dump. When Buffy and the Scoobies see Toth in the garbage landfill, he uses a rod device called Ferrula-Gemina blasting a ray against Buffy but hitting Xander instead. Toth vanishes and the group leaves the place with a confident Xander. Later the insecure Xander awakes in a pile of trash, follows his double and meets Willow to tell about his clone. Giles finds that the ray discloses one person into half, distilling personality traits into two separate bodies. Further, if one part is destroyed, the other will die. While trying to find a mean to unite Xander, they have to face the evil Toth.
