Regarding mirroring Diana’s facial expressions – there is something there. A certain fetching look that is part natural but certainly played up. I’m sure Harry sees it and it plays to his subconscious.
I’m not sure it’s mirroring per se but Meghan has, like that article said, a very “child-like” way of presenting herself–lots of giggling and “oh gosh” expressions and stuff like that. It’s a bit off-putting on someone who is 36 yrs old.
Diana did something similar with her doe eyes and whispery voice. It was charming when she was young, but it started to look manipulative when she got older. The Panorama interview and the Diana tapes are perfect examples of it.
