Interesting questions Sean, thank you.
The previous frame does indeed have the boy looking away, and he is is in softer focus again. The girl is the focus - she just performed a dance for us and seemed to be having a moment's reflection. The little brother was reluctant to look at the camera and I guess I felt clever for capturing the moment when he did, and like the alignment of the eyes, tho' a pure fluke.
Maybe a bit of sharpening on the girl and softening on the boy, with another look at that previously ignored image.
Cheers
Ian
