At the Alpha-Delta house, the members are getting ready for the party. One finds a symbol in an old book to paint on the floor. Anya goes to see Xander, wanting to know where their relationship is heading. He agrees that they're somewhat dating, inviting her to the party. Buffy, who skipped her psych class, visits the professor and asks for her assignment, but she receives a cold response. Riley, however, gives her the assignment, telling her to have fun on Halloween. Oz and Xander carry a sound system to the Alpha-Delta house, and Oz installs it while one guy paints the symbol from the book. Oz cuts his hand, spilling drops of his blood, which activates the ritual to summon Gachnar.
