Alan's secret identity!
Is there any reason why the pagan celebrant got Alan's name wrong? He introduced him as Alan France. We then heard it mentioned later as Alan Franks.
So how about this one - two related versions if the name, both used in their entirety by the writers today, a cloud of suspicion over Alan's honesty. I'm hoping for a shocking unmasking if a secret criminal identity and a reverend run out of town by a restless lynch mob.
