I enjoyed that episode and was so proud of the Marthas. Cool bunch of women, keeping under the radar and getting people out! Love them.
It was interesting to watch Serena not be able to give up who she was. She was an orator, a planner, an architect of a regime - but now she is powerless and she can't accept it. I'd say the penny finally dropped there and maybe her allowing baby Nichole to escape was actually a power grab, as it was a decision she could actually make.
"Go fuck yourself Fred" - best line ever!!!!! What an absolute arsehole that man is. No redeeming features at all - as far as I can tell.
I thought Rory Gilmore was superb. Haunted, destroyed Emily. You could just feel that she was a woman on the edge. The spiteful comment by Aunt Lydia tipped her over.
There is clearly a significant underground movement - but it won't be enough. In all the totalitarian regimes of modern times, there has always been an underground movement but to the best of my knowledge it has never brought a regime down - although if someone wanted to contradict me, I'd actually be pleased! 
Praise be bitches - I have loved discussing this programme with you all.
