Comments of chapter undefined of A Bend in Time

Author, what a strange dinamic would the Black Sisters (Tonks and Malfoy now, really) have with a newborn as their half-brother? I can't help but empathize with them, I would be both livid and weirded out to have a toddler as a brother while I have one of my own. Probably the dinamic would be like that of aunts and nephew instead of sisters and brother.
