This is a very moving episode, which touches upon important issues of material and spiritual needs, and how communities should be organized and governed.
Roy Herrick does a nice job as an Anglican priest who has recently joined the Whitecross community. He experiences doubts about his faith, and whether he is adequate to help others with their needs. Through his struggles, others begin to understand how they need more than material things to live a good life.
A lot of physical work is still necessary for the community to thrive. The leaders Charles and Greg show how their characters and strengths differ, yet they share a strong concern for ensuring that the community survives, and they are both frustrated that some community members don't seem to be working as hard as maybe they should. Denis Lill and Ian McCullough are excellent in portraying gifted but flawed men who try to do the right thing.
Judy and Philip are additional newcomers, a young couple who raise important questions about whether Whitecross is in danger of becoming a totalitarian community.
We also see interesting aspects of some of the regular characters. Hubert shows a new, sympathetic side. Arthur demonstrates wisdom, and we learn a little more about his past.
There is a nicely understated, touching depiction of some of the community members joining together in a worship service--their first since the catastrophe that they refer to as The Death.
