Normalizing self-interest over morality is a striking theme for this episode in light of current events in the United States. The very thought of the Handmaids, already treated as livestock and slaves, being Gilead's chief export good is horrifying. I'm glad June found the strength to speak up to the Mexican ambassador (even if it was awfully convenient they were alone for just long enough), but her pleas fell on deaf ears. At least the ambassador's aide is sympathetic, supposedly in contact (or able to be in contact) with Luke.
I like the subversion of expectations: June thought the Mexican ambassador was a man (or at least played the role of assuming that for the benefit of the Gilead officials) and thought the ambassador for would be sympathetic to her dire situation. Conversely, she didn't seem to expect that the ambassador's aide, a man, to not only be sympathetic, but also be part of some kind of underground movement.
While I appreciate the attempts to humanize Serena Joy (which I'm guessing is not from the novel), I cannot feel sympathetic for her. She help bring Gilead into being, both the good and very ugly, and I cannot feel bad for her lowly losses. Instead of "woe is her," I want to see action from her, but I do not expect it to happen.
Sad there was no Moira in this episode. Likewise, Emily although I don't expect we'll see her again after what she did last week, fertile or not.
