Eden breaks my heart. The actress killed it this episode. She's so lonely, she's trying so hard, she's doing everything she's been told and shown is the right thing (keeping house, cooking, paying him attention), and she can't understand why Nick doesn't love her. And Nick doesn't even have it in him to talk to her about it, so she thinks it's all her fault. She has no friends and no one to talk to or confide in. There's a little farm near me that I buy eggs from sometimes, where they post Bible quotes in the yard and the wife and daughters all wear plain dress, and I think of Eden when I go by there. Nick is in a shitty situation, but so is she, and her efforts to make something positive out of it don't and can't work.
I read an interview with the writer of this episode in which she says that her intention was that Fred arranged the meeting with Hannah out of guilt at what he had done to June (of course not realizing that that was basically exactly what he's been doing to her every month, only this time she was "present" for it) and not as an intentional trap, which makes sense given that he wouldn't want his 9 months pregnant handmaid to disappear AGAIN. He might or might not be invested, but Serena certainly is, to say nothing of their entire social circle, and I can't see him destroying this thing she's so invested in on purpose. Also, it's been made clear that the status of a Commander depends partly on his progeny; that baby is valuable to Fred on multiple levels.
