Continuity mistake: When Corrine takes off her blouse, she shows her children seventeen scars on her back that she got from being whipped by the grandmother. Later in the movie, when Corrine is dancing at a party, she is wearing a strapless dress and there are no scars or any signs that she was struck with a whip.
Question: It's been established that the grandfather has no knowledge of Corrine's children. When they come across a copy of his will, it states that if it was ever discovered that Corrine had children from her first marriage, she would lose everything. Since he never knew he had grandchildren why was this clause ever added?
