Trevor’s blind, elderly great-grandmother, who spends all her time sitting next to the gas stove in Frances’s house in Soweto. Because she is immobile and only occasionally chats with Frances, Trevor considers her something of a nonentity, which gets him into trouble when he decides on one rainy day to defecate inside the house rather than going to the outhouse—she smells it and convinces the family that their house is haunted by a demon.
