The System does transgender their children to avoid killing their sons in ritual.

I appreciate and I'm open to your idea, but I'm not 100% confident on Carter being redressed as KG only because of her present day physical size and height, Carter was as tall if not taller as Anderson. Reports are KG is 5'3" tall and Anderson is 5'10"

You could very well be right.

KG reeks of evil. I think she was born without fully formed genitalia, what they used to call a intersex, and her sexual identity was chosen for her. Her bones and body is neither masculine nor feminine.

I'm looking for a photo that shows their relative height towards one another.
