Also, snow in Autumn? (trees leaves were just starting to turn brown but nowhere close to falling). OK I'm picking but there was no need for snow machine.
There was a lot of time hopping - that awkward bit with Tom delivering Barbara's cases, with excitable bad driver nun whose name I can never remember saying "it's only been two weeks" and then Tom went away to see his parents "for a while" etc. I think the snow starting to fall was meant to indicate the passage of time.
In the CofE you are first ordained deacon then later priest (and eventually bishop if you keep going). Curate is a job within a parish. I think you'd often take a curacy after being ordained deacon, but then be ordained priest and stay in post as curate until your own parish comes up.
I was chortling when they delivered four babies in five minutes, because of our remarks last week and as though their birth ratio for the series was down so they sorted it out at the last minute.
