Mary says to Ariel: "I wonder what you would think if you were to die and Claudia were to find someone else." Claudia, who believes that Mary is a prophetess, tells her to shut up. Mary begins to move away from Cholo and asks Cholo to leave the business he has with his brothers. Mary becomes increasingly sad and sullen. Cholo gets a day off. On the day that Ariel takes Cholo's place at work, an accident occurs with the delivery truck and Ariel dies. When Mary attends the wake, Claudia tells her to leave and they stop talking to each other. Mary's "prophecies" continues to be fulfilled: After Ariel dies, Claudia finds a boyfriend and plans to remarry. Mary gets more depressed, retreats from Cholo's family and begins to wear black. Only Cholo's sister Luisa still visits Mary, but Mary prophecies Luisa's, and her own, death. Thus Mary imagines the progressive death of all of Mrs. America's children-in-law. Mary's rejection of her in-laws affects her relationship with Cholo. Mary has nightmares, suffers depression and isolates herself from the world. When Luisa gets sick with food poisoning, Mary finally loses her mind. He says it is fate that Luisa, and then herself, die. Luisa recovers, but Mary is asleep when Cholo returns with the good news. When Cholo is asleep, Mary gets up, strips herself naked, puts on her wedding dress, and takes a knife. Mary goes to the bedroom and kills Cholo by stabbing him in the heart.
