Oh, so you're saying since the little girl who's last name is the same as Amy Adams' character(Anna Fox) that must be her daughter?.... And the little girl is played by african american(mixed) actress Mariah Bozeman. So to you that means her and Anthony are a couple even though his character don't even have a name that made that little girl together.
Good detective work... but the problem is there is another black man in this and although he don't have the same last name that don't mean he couldn't be the father or since Anthony's character doesn't even have a name that the father is even in the picture... but we shall see.
