After he heard about Ronald's trial, Harriet decided to lay low in the meantime. He removed all of the traces left by Emir so no one can follow him. Harriet decided to leave their kingdom in the meantime to find a few methods to control his evil persona.
Before he left the kingdom, Harriet visited the Dresvil Mansion. Through the window, he can see a man in his forties sitting on a sofa. There was also a little girl sitting on his lap and she was holding a storybook in her hands. It seems like Harrison's granddaughter was trying to cheer him up by reading him a fairytale.
Of course, Harriet knows who is that little girl. She is Clementine's beloved daughter, Penelope Dresvil. Because Harriet kept an eye on his family in secret, he knows a lot of things about his granddaughter. That also includes her background.
