From a still, we have no real idea if that's a representative image, or simply an unfelicitous moment whilst moving turning, ending a smile to speak or whatever.
And yes, what would be the point of showing her smiling, when your narrative is to say something else? That is the very essence of confirmation bias.
Just like that horrible interpretation of Kate's briefly resting (and bitchy looking) face when turning from smiling/waving out of one window, and just before looking animatedly at William, was taken as evidence of unhappiness and lack of love.
That was wrong and this is wrong.
It's nothing to do with whether or not the viewer is ND, it's to do with whether we are seeing a fair view in the first place. I do not think we can ever be sure that is the case with stills, nor with v short clips. They are selected to confirm the hypothesis.
I think there is far better evidence on this than trying to extrapolate micro-expressions from stills selected for effect.
The actions of the Hollywood Reporter in publishing, and standing by nay extending their story in that short vid, plus that coming out despite her being a WME client; that's what I find damning here.
Plus looking at Harry's words and actions over the years
