Respectfully snipped. I'm wondering the same thing, or something along those lines. If dad is of Indian descent, I am wondering about some kind of customary beliefs where he would fight for or believe the father should raise male children, the mother raise female children.
While it doesn't make a lot of sense to those with American culture, I wonder if perhaps mom believes dad would only fight for custody of the son and has no interest in custody of is daughter, so he hid the son?
I could be wrong, but this is the only scenario which makes some sense which leads me to have some hope Sky will be found unharmed. Or not, if mom wanted to hurt dad by taking away his son over the pending divorce.
Do we know if dad is bio father to both kids? Just curious as it may or may not fit into my above theory.
Praying Sky is found safely soon.
