Factual error: Angelo claims he promised their mother on her deathbed that he would become a priest, and Sophia says she promised she would marry someone else - and we assume she died before Sophia or Angelo got married to their spouses. However, in the episode where they are flashing back for Mother's Day, Sophia's mother is in this episode along with Sal (and she looks like an older version of Dorothy).
Factual error: A 250-year-old sea chest recovered from the ocean floor is opened, and all its paper items are perfectly dry: the log book can be opened and read, and the letters can easily be unrolled. Highly unlikely. The chest's wood and pitch would deteriorate (salt water is extremely corrosive), and the paper should be damp and crumbly, at the very least. Even more likely, it would have become a lump of unreadable sludge.Jean G
Factual error: 2-7 "The Crimsom Avenger": At Dunwyn Erwyllan grabs a bundle of money bills from a fishmonger. It may be just a curiosity since paper money wasn't used in real medevial times, but it is still odd as gold coins are still in heavy use in all other episodes. Even the royal treasury, which is robbed in this very episode, has only bags of coins and no bundles of paper money.
