They also give some further info on Katherine:
Poor Katherine Howard. She was a horny young teenager and Henry was a fat old man with a crusty sore on his leg when he fell in love with her and made her his Queen.
He called her his “Rose Without Thorns”, but poor little Katherine fell in love with the sexy rogue Thomas Culpepper and so she was beheaded. So as not to make a mess of things, she had the chopping block brought up to her room so she could practice on it. The last laugh was Katherine’s: standing at the scaffold, she said “I die a Queen but I would rather die the wife of Culpepper.” which probably pissed off Henry really good.
