Patricia was in a difficult state, she never expected that her daughter whom she was depending on to get something in the future would just kill herself like that.
Why did she had to do that after everything she had done for her? Patricia wanted to blame someone and Arianna who had caused her daughter to end up in that place became that scape goat.
If Arianna had not cursed her daughter, made her so old and exposed her, Amy wouldn't have been expelled from school and left the kingdom. Her baby would have been still with her and by her side.
Patricia knew that she had neglected her daughter for years but who cares about that? She had been trying her best to make up for it lately even though she knew that she just wanted to get some gains from her and nothing else.
