I forget what triggered the thought originally, but now it explains a great deal of why the heroine slips through cracks in places. No one knows enough to catch her. Hmmm -- there shall be one reason why they want to catch her, but not the three that have occurred in the other story.
And she may show up in the other story as a revered elder.
