The photos at the end.
Was the photo of the school-age child at the end Elizabeth or Karen?

The girl was Elizabeth, but I'm unclear on who the boy was. Did I miss something here? Could it have been her son?
EDIT: Another post suggests the photo of the "boy" is actually a younger photo of Elizabeth, which makes more sense.
