The plot twist of Cinderella is that Cinderella is actually sweet and good and hasn’t been using her deliberately-cultivated mouse infestation to acquire enough rat poison to slowly kill her step-family over the course of several years by baking it into their morning scones or some shit. Biding her time as they get weaker and weaker, and thereby even more dependent on her assistance (and easier to subject to a multitude of other substances), until the doctors are baffled by the myriad symptoms and ineffectual treatments.

Then when the corpses are burned after her step-family dies of some mysterious disease Cinderella just weeps in relief-feigning-grief and dabs their ashes on her cheeks, vindicated in her justifiable homicide. The sole surviving inheritor of her family’s estate, no longer subject to the abuses of her relatives, or in danger of losing her family’s remaining holdings.

So in conclusion I guess Cinderella is a much better person than I am and I wish her all the best with marrying up.
