When asked about the magical aspects of Salem, she said that the series was based on "all natural magic", and identified her character as a "psychological murderer as well as a practical murderer". Defining the show as using "murder in the parlor" and "women fighting to the death in a very elevated way," Lawless emphasized that it treated magic differently than the Harry Potter franchise, commenting that there is "nothing cute going on". She said that Ingrid's story arc was partially based on the character's obsession and rivalry with Mary and the inevitable vendetta to destroy her. Bustle's Kelsea Stahler identified Ingrid as Mary's foil, emphasizing the ability of Lawless' character to charm and appeal to the city of Salem and its inhabitants.
