Eustace Chapuys, Imperial ambassador, is said to have died in Spain soon after he left England, in 1545. Actually he lived in the Low Countries until his death in 1556.
Charles Brandon died in August of 1545 (18 months before King Henry), yet the date is shown as December 1545 in subtext, and he is still in the crowd before the King's speech at Church.
Charles Brandon's son Henry by Catherine is seen to be an adult. He however would have only been about 12 at the time the episode takes place in.
