Been lurking here a while - just a couple observations.
I think Serena's character isn't complex. It just represents human nature. If it doesn't directly affect us, we don't care (ask any black person living in the US whose ancestors have already lived Gilead). Also, I find it very telling that everyone is cheering Lawrence as a hero - yay Lawrence! even though it is revealed that he engineered Gilead, but for Serena, who may be slowly coming around to see her error - off with her head! I can't forgive her! Let me be clear. I am not defending her - just pointing out the hypocrisy because Lawrence's wife has clearly observed some atrocious things, including the rape ceremony which at some point he probably took part in. Women are terribly unforgiving of other women and men somehow get a pass.
Finally, as mother, I could not actually live "free"in some country while a child of mine is left behind, so I understand June's choice. We have no evidence that Canada is doing anything except gathering info and offering asylum - which I am not downplaying. But how many atrocities are occurring in the real world we live in that the world is silent about or if raising awareness not actively resolving?- particularly when women are the main victims. Countries offer asylum when they get out, but movement to save people usually doesn't happen unless there is some economic benefit or economic danger to the (mostly) male leaders of these powerful nations. Sadly, the show reflects the world we live in but viewers are pissed that it is not giving them the satisfaction of resolving the issue quickly (in a year or two?). Slavery (of African people) went on for over 400 years people. The events surrounding the Holocaust - over 10.
As for June constantly escaping punishment, that is because Fred likes having her around for his sick purposes. He spares her to torment her and he has the power to do it. I agree that this one will be hard to come back from. Janine faced death for putting her baby in danger, so hiding or kidnapping a baby should draw death (unless by some plot twist Serena and Fred agree to pretend that they still have a baby).
