zsAkris was right, Ginny has seen madam Regina unleash her fury on the Duke before and with the brand of a traitor at the back of his hand, he could not do anything to his mother who seemed to have given birth to him as if to just annoy the heck out of him. She understood that there was no way she would be able to save herself from the incoming doom, so when she heard the Duke dismiss her, she lowered her head and walked out of his room not saying a word.
Maybe she will just go and look for the most ugly dress there was so that no one will pay any attention to her. But then she was reminded of what her mother had once told her——
' We are sirens, Ginny, even if you were to wear a potato sack you will be able to attract the attention of men from a mile. So, make sure to use that beauty of yours to the full extent and prove to me that you are worthy of carrying my blood.'
