Just to echo what Octavius says, be careful of believing ANYTHING in The Tudors TV series.
The have invented characters and events, merged two characters into one, moved the dates of events so they look like they happened at the same time but were actually years apart.
For example Henry had TWO sisters, Mary and Margaret, but the sinlge character "Princess Margaret" in the series is a merging of both sisters, and she does things that both sisters did.
Also Henry's illigitimate son from Betty Blount did not die as a child but was 17 when he died.
Loads of other things are "made up".
It is really just a soap opera that happens to be set in medieval times.
Would not be surprised if Henry wakes up in the shower at the end and finds it was all a dream like they did in Dallas.
