impregnate her and then have her tell everyone that she was raped so no one can blame her or hate her for it. No man wants to marry a woman who is pregnant with another man's child so that will kill the arranged marraige. Her grandparents and parents can't get mad at her because that would be evil after all the trauma she's gone through getting raped and all. They will support her and your child then you can marry her later and viola!! simple, ne?
