The baker Josie Breen is Leopold Bloom’s ex-girlfriend, who went on to marry the lunatic Denis Breen instead. When Bloom first meets her in the novel, he notes that she has aged poorly and looks disheveled, perhaps because of her stressful, thankless marriage to Denis. She first tells Bloom that Mrs. Purefoy is in the hospital, and she reappears in one of Bloom’s fantasies during “Circe” to reenact the time when they were dating. Many of the novel’s characters (including the Blooms) feel sorry for her because of her marriage, but during “Penelope,” Molly Bloom also speculates Leopold might be having an affair with her.
