She had worried whether Joanna's birth parents might be some sort of important figures.
But she thought such a possibility was very slim.
How could that little wretch, Joanna, have such good luck?
Even if her birth parents were indeed significant people in the past, they must have done something wrong, hence leaving her behind.
To abandon their biological daughter, they must have committed very serious misdeeds.
