Response to the Forth Part of the Handmaid's Tale

In the forth part of the book the Handmaid's Tale, a lot of unexpected plots appears. In the ceremony, Offred says that she thinks love is important in their day-to-day life. It is unbelievable for a woman to say a such word in that society, even Offred has communicated this topic with her commander. When the ceremony is over, Ofglen asks Offred whether she is making appointments with her commander. I am confused here. The appointments between Offred and her commander is a secret, but how can Ofglen say "We know you're seeing him alone."

    In the following chapters, the commander even takes Offred to a club, where they meet Moira. In the toilet of the club, Moira tells Offred how she came to the club, a lot of Quakers helped her to hid in their house. However, she was still caught when she nearly left the country successfully, and was took to the club where is called Jezebel's. 

    There is another unexpected plot. The wife of the commander should talk to Offred, and told her that she can be pregnant with Nick. This is also not allowed in that society. But a lot of wives of commanders choose this way to let the handmaids be pregnant. Though wives of commanders have a lot of rights to ask their handmaids do anything for them, I think it is not fair to push the handmaids to do everything, no matter it is good or bad, even, the wife of the commander uses the photo of Offred's daughter to threaten her. In the wife's mind, the handmaids are just a tool for her family to get a child, so they do not need any respect.
