I hope we still see James Cromwell in the show because George was quickly becoming one of my favorite characters on the show. At first, he seemed annoying because of how interested he was in the environment and the bomb shelter, but after it became clear of what was going on with him and why he was so obsessed with it, he became less of an irritation and more of a tragically injured character.
Ruth leaving George makes me upset but Frances Conroy is such a good character that I can feel for both characters at the same time. It was nice to see Patricia Clarkson and Kathy Bates return. They bring such an easy-going feel to the show. I loved the way the episode was a girl-power congregation and the intensity ended up dwindling down near the end, after they all go down to visit their friend that died and sing "Calling All Angels" to her. It was a touching moment in a show that knows exactly how to do touching moments.
As for the rest of the cast, it was hit or miss. Rico and Vanessa haven't interested me all season and this was no exception. The whole au pair plot was pointless and was the type of odd storytelling I typically don't like from the show. I really did enjoy Billy and Nate talking through, talking about first loves and how you shouldn't waste your time on somebody who doesn't love you. The show sometimes plays the same tricks on us with the relationships between characters so it's nice to see the writers give certain characters different beats to play with each other.
We also get our first glimpse at Anthony and Darrell, the two adopted kids. Darrell is the typical angry foster kid who hates everybody and makes a hard time for David and Keith, but it should be interesting to see how those characters evolve over time. Right now, the two adopted kids haven't interacted with the rest of the Fishers so I'm looking forward to when that happens.
