What is their story viz. their marital status? Aubrey has 5 children by herself and is only 28--she must have been pregnant for the last decade. I was shocked to learn she had so many kids--she neither looks nor acts mature enough to be a mother to so many. I had her (and her sister) pegged for entitlist college students.
If she is struggling just to feed her children, one wonders who is taking care of them while she's on the ranch? Unlike most parents on the show, she does not have a spouse to take care of things on the home front while she is chasing her dream.
I hope she's not counting on the prize money to keep her family afloat because chances are very good that she will wind up disappointed. I don't peg either sister as the biggest loser.
