True, altough, from the mc family we only know the sister and uncle, and the records stop at grandparents, if i'm not mistaken and it doesnt say hair color/ethnicity, isn't uncommon for a child to have the grandmother/father, or great-grand, also the black hair its a dominant gene, altough the asian ones are rececive, but they still appear in 1 to 10... mmm... could be inbreed consecuences but doubtful.Nelle looks Asian and has black hair... neither the MC, anyone in his family or the Fairy Queen share these genetics.
Or perhaps we are wrong, and nell in reality its half-demon
Let's the conspiracy start
