I think C.W. had an idea that SW might be pregnant before that video was taped. Most wives tell their husbands when their periods are late before the actual confirmation of the pregnancy. That’s not something you keep secret when you’re trying for a baby, and SW doesn’t seem like the secretive type to me, anyway, she was an open book. I think CW walked into the house, noticed the t-shirt SW was wearing, noticed that she had the camera going, noticed that he was being taped, and then he went along with it. That’s who he was. He never shows excitement or enthusiasm in any of their videos, he’s not the kind of guy who jumps up and down screaming with joy.
