When "The Astronaut's Wife" is in the toy store, she discusses with a man what happened with the woman who killed herself. He says she was "3 weeks pregnant with twins." What is wrong with this, you ask? Even blood tests may not pick up a pregnancy at 3 weeks (menstrual age), and at that early there is no way to tell if it is twins, even if a dialation and curretage was done. Anyone who has ever been pregnant, or had a pregnant wife should know that you probably wouldn't know about a pregnany that early, and you especially can't tell if it's twins! Even if you give the writers the benefit of the doubt, and assume they mean 3 weeks past conception (5 weeks menstrual age), they still would not have been able to know it was twins. Especially since they were supposedly identical, like the blond-haired lady's.
