It's bad enough in "An Old Story" that the brothers are being magically aged into older men by consuming prunes. But what makes it even worse is realizing just why she's aging them up. Dahlia planned on turning two adolescent boys into old men so that she could sell them off to elderly women so they could marry the boys. And apparently does this fairly regularly.
Even worse than that is, at the end of the story, the parents come to the realization that neither of them are actually related to Dahlia, they both thought she was the other's relative. Meaning that it's highly likely this woman was infiltrating multiple families by pretending to be a distant relative, merely so she could gain access to young boys who she could groom into marriage partners for much older women.
