Miss Melba co-manages the Kettle Coffee shop with her father. She earned notoriety for brewing teas and coffees widely considered unpalatable, prompting her father to handle most brewing and cooking tasks. Her demeanor is marked by notable kindness and attentiveness toward patrons. This warmth, particularly directed at Doc, sparks his misinterpretation of her actions, leading him to develop romantic feelings. Her own feelings toward Doc remain ambiguous and unclarified. Functionally, she facilitates interactions among the main characters. Her encouragement and praise, especially aimed at Doc, serve as motivation; for instance, her admiration for his presumed willingness to assist Seth influences his decision to help with Seth's magical training. Her father, Mr. Melba Papa, exhibits a protective, controlling attitude, physically stepping in when Doc displays overt affection and subjecting Doc to repeated harassment. Her role remains consistent as a supporting character within the café setting, unchanged in evolution, backstory, or involvement in major plot developments beyond these interactions.
