At first, I thought casting a younger man as Fred was a bad decision, but it's growing on me. I think it's even a little creepier coming from Fred just because he is younger. I'm in my mid-twenties and I think many of my male peers would be more progressive and wouldn't stand for a Gilead-type thing, but then again many would. As June said, he tries to make a connection, maybe so he can "get-it-up", maybe for other reasons. I thought him nonchalantly asking her to get the dictionary was a good moment. For him, it was nothing, but for her, it was a big deal. For someone who most likely loved books (having been in publishing, I believe?) and was clearly intelligent, and someone who was denied even the right to read and write, I loved to see her run her hands over the books, as if she were remembering the "before".
I enjoyed this episode because it showed a lot of characters' motivations. Every decision the handmaids get to make is a huge decision when they have so little choice. As others have said, I especially enjoyed the handmaids giving June the food, which I think served as both a thanks and a big ol' f-you to the aunts. There can still be solidarity, even in the loneliest and most desperate of times.
As for the attempted escape, I think it helped June to think of her friend as having escape. I think that may have been why she was so jarred in Ep 1 when Janine said Moira was probably dead - not only was she thinking about her friend dead, but probably a lot of her hope as well.
I think I might've gone crazy and killed myself after two weeks in isolation. maybe she had the martha to bring her food, but I imagine Serena Joy would've punished her for any more conversation than what needed to be said. Maybe the isolation is what caused previously Offred to hang herself.
