I couldn’t help feeling that Nathan’s Great Grandfather’s story was the beginning for one or both of the following reasons.
First: Because this ‘affliction’ has carried on through the family, all the way (so far) to Lara’s mother, then Lara herself, it makes me question if Nathan’s great grandfather’s cruelty was also rooted in a type of insanity.
Second: Clarity’s curse. “You will reap what has been sown.” The phrasing suggests the beginning is embedded somewhere in the past. Perhaps Clarity knew or was close to one of the boys in the mine and is seeking vengeance against the mine owner and his descendants for his disregard of the boys’ lives. Whatever the reason, I believe it was a curse and not a blessing … something to follow this family and their children forevermore. Perhaps Gabriel’s mother was similarly cursed, and should we be afraid for Nathan and Charlotte’s daughter? What form might this take for her future? (Series 2?)
