I just don't, or can't, believe that Anna knew. What person in their right mind would marry into that? Especially knowing that she would be having kids as soon as possible. I'm a casual watcher at best. I read more here than I spend time watching the show, but from what I have seen she does seem like a good mother. Her kids seem engaged in that they are doing, excited, and interested. She appears to truly love them and care about them and for them. From what I have seen of her as a mother, I just can't believe that she knew.
