I did watch it - I may have missed that one. I remember vividly the episode regarding the leper. Those series were iconic, IMO - Claudius, Brother Cadfael, and others.
WARRIOR: Good father, where did you learn to wield the quarterstaff like that?
CADFAEL: I am but a mere brother, but I was in the late Crusade.
WARRIOR: You were at the Siege of Jerusalem?!
CADFAEL: I was.
WARRIOR: We must share a tankard of ale. I must hear about that.
It turns out that the young warrior is Cadfael's son by a Muslim woman he bedded during the Crusade before he became a religious brother.
