I think June knows that Nick is not squeaky clean because when Fred and Serena took her to (?) Boston to speak to the Swiss they refused to speak to Nick because he had committed atrocities.
She knows he's done awful things. She has too.
Agree about Lawrence, he's an economist and that's what he cares about most of all. He set up a good model for Gilead and it has failed because idiots didn't follow his instructions. Now that his wife is dead he is pretty rudderless as far as human connections go. I think he enjoys June, finds her amusing and interesting and I think he respects her, but I doubt he'd put himself at risk to save her. He's an intellectual who cares about markets and had the opportunity to build a new way of creating a functioning, wealthy society - which has been ruined by people he regards as incompetents, so, he's pretty annoyed by that.
LOVE the new Lydia. I think June telling her that she had failed to protect the handmaids might have an impact on the way she treats this new "batch". Perhaps she'll be less vicious, she needs for them to trust her so they'll tell the secrets of the households. She's worked out enough to be of value to Commander Lawrence, but, really, she could be hugely powerful with her inside knowledge. I really enjoyed her trying to blackmail him and him escalating her proposal. Perhaps they'll land up working together to get rid of the dead wood Commanders who's poor decisions have destroyed the vision they both had for Gilead.
I think the writing is still really strong. And I'm very glad to see Moira and reckon Janine is alive but under rubble so they'll find her in a field hospital.
And then they'll all live happily ever after
