I only got round to watching it last night. I'm pleased that Luke behaved the way he did at the protest - I was starting to think he'd given up hope, but now think he'll be fighting to get her out somehow. I thought that June's reaction to hearing about Luke was great too - certainly cleared up any "would she choose Luke or Nick" questions - Luke every time. Her smile, despite the horrors in her daily life, when she heard news about her husband and best friend was so wide.
I don't think Eden is going to be the problem that others think she is. I think she will be her own undoing, but not anyone else's. Seeing her with Isaac, enjoying the attention she doesn't get from her husband was interesting. It's been interesting seeing the differences between her and June and Serena anyway - Eden has grown up in the regime, she doesn't (necessarily) remember a time before - and even if she does, she was very small. She won't have experienced the normal teenage stuff that June had, and that Serena had, so I thought the scene with her and Isaac was interesting as it's showing Eden as a more "normal" teenage girl. I don't think she's got enough about her to deliberately do anything to hurt Nick, though I might be wrong.
I loved all the stuff in Canada with Serena - my favourite bit was where she said to the the US guy (Mark?) that she wasn't going to betray her country and he replied "I thought you'd already done that". I have such conflicted emotions about Serena - sometimes I think she's just in survival mode, and that explains why she behaves as she does towards June, but then I remember that she was instrumental in the creation of Gilead. I wonder if it will fall and she and Fred, along with so many others, will be held for war crimes. It did make me think of the Nazis last night - those who just went along with it, committed atrocities, but would claim they were just following the rules. Aunt Lydia falls into that too.
