How much do you want to bet he's a nigger and she's a mudshark? In a real poly family, every member knows about everyone. Kids are raised by the group of adults who all live together. This mess looks more like a nigger buck who can't keep muh dik in his pants and a mudshark mother who can't get her priorities straight and who puts up with it rather than lose the buck.  The daughter is at the bottom of the priority list, being kept in the dark and forced to live a lie by a selfish mother. I'd sue for emancipation too if I were that girl.
