I don’t think she cares if she’s accepted or not, as long as she can spin it that she is, or do the Angelina Jolie trick of acting as if you are in conversation with somebody when you’re not. The queen smiles and watches a performance, looking straight ahead, you become animated and chat at her even if she’s not responsive. Kate looks at/says something to Harry, you look up and smile/laugh as if she said it to you. She doesn’t care if it’s real. Image is all she cares about.
