She is empty inside. She has to watch other people to mimic their reactions because she hasn't a clue how to act. She has no empathy with other people. She doesn't have an original thought. She has to steal stories, quotes, fashion, and ideas from others. She lies constantly and changes the lies later because she doesn't remember what she said before. She is always on the make. Looking for the latest opportunity to advance up the social ladder. Uses up boyfriends and husbands to suit her purpose. They are expendable. Now using two kids to sell merchandise until they are no longer profitable for her.
She is a born flirt. Flirting with men. Flirting with the camera. Flirting with celebrities who she thinks will help her. She sees all women as competitors and natural enemies. She doesn't like women, not even the ones she calls her friends. They are only her friends when she can use them to achieve her goals. After that, she discards them.
If Diana had lived Markle would have turned Harry against his mother just like she has turned him against all his family. Diana would have seen right through her. Meghan can't have such a woman close to Harry. Harry would have trashed his mother just like he trashed his father, brother and sister in law.
