03E02 - Dead Man's Party

Buffy is back home, to her mother Joyce's great relief, which calls for a dinner invitation for the while gang. But the mood remains gloomy, despite her resuming the main slaying tasks, because others things can't just return to their former state. Partly because the obviously amused principal Snyder pays no attention to pleas to take Buffy back (mother's threat to take the case to the mayor even has an inverse effect). And Buffy still dreams of Angel. After a dead cat found in the Summers bookcase reanimates, other stinking corpses come to life again, a phenomenon which might have something to do with a the mysterious Nigerian mask with lighting red eyes Joyce bought, fortunately no secret to Giles.
