The flow of the images makes more sense to me, now.
BG is about to strike, the image with the blurring around and adjacent to BG's right leg to me seems to have edited out Abby, which a lot of us have figured for some time, I'm sure. She's moving towards Libby,, and just happened to be taking up a lot of that frame before the image was zoomed, edited, cropped, etc.
He's pivoting, look at the pivot in the hips, plus the angle of his entire body changes as if it's a sudden pivot
Sorry....learning how to reply as I have just recently joined the group.
Oh....that pivot. Such a perceptive view. It makes me sick at my stomach.....knowing that at just that moment the world changed forever for those two babies, those who love them and those of us impacted by them.
