The class divide between the wealthy Danzards and the impoverished sisters creates the essential tension that poisons every interaction.

This systematic dehumanization and the sisters' desperate economic dependence trap them in a volatile situation where even minor conflicts feel catastrophic.

Foreshadowing: The opening scenes establish the class barriers that deepen throughout the narrative, setting the stage for alienation.

Christine persuades Lea to stop sending their full earnings to their mother because she wants them to keep some money for themselves and achieve a degree of independence from their manipulative parent.

However, this financial independence comes at a cost, their earnings decrease and their work quality suffers, drawing Madame Danzard's critical attention.

Foreshadowing: This decision reflects Christine's emerging desire for autonomy, but also her increasing control over Lea.
