The bit where Serena lashed out at Rita and nobody said anything about it.
Because Rita and June can't and Aunt Lydia didn't care.
I felt really upset for Rita because she seems to have taken to being in the household and she cares about the people in it. She is obviously frightened by Gilead, as we saw when she gave back the letters, but also she seems genuinely fond of Serena and June as women in the house. She was excited before when she thought June was pregnant, and concerned about Serena when something happened (I forget what, but I don't think Serena was sleeping) in the last series.
It bothered me to see her treated violently because Serena wanted to hurt June.
I think that the other Wife was at the baby shower, the one that has Janine's Charlotte (they call her Angela) and I don't think that she's overly bothered about having a baby. She doesn't seem to care in the way Serena does. I think she likes the status of being a 'mother' more than she likes being a mother.
I wondered what that was like in Gilead, for Wives who don't want to be a mother but they are expected to be because children are everything, not least a status symbol of your husband's fertility.
