Distorted, yet genuine love: For her, the children of the house are "destined to die someday." That is precisely why she possesses a distorted maternal love born from despair: "At least until the day they are shipped, I want them to die loved, in the greatest happiness, without hunger or fear."
Resignation born from a harsh past: She was once raised in the house just like Emma and the others and had a past where she aspired to escape. Because she learned the truth of the world and despaired that she could not escape, she has a strong sense of resignation: "Do not resist, accept the system, and do your best within it."
