Thank you Jackie
Dr Who ( Patrick Troughton also Mr Quilp) plays the part of Duke of Norfolk, and it is pretty obvious that the system was
"It is you or your family - now choose!"
and he chose Katherine and then Lady Rochford who doesnt come out well ( tongue incriminates other people - - and then it is her turn)
1540s were an interesting time, and you did whatever was necessary to keep your head. Reform, extreme prot, back to Rome, back to prot ( less extreme) - oh lardy lardy !
