Ah, Iohanna Regina.
First of all, Jane Seymour never thought of Mary Tudor as a threat. She truly loved the princess, seven years her younger, and was loved by her in return. Mary was tormented with grief when Jane died, and acted as the chief mourner at her funeral. During Jane's time as queen, she went out of her way to bring Mary back to court. There is evidence to prove that she and the princess were friends before the usurption of Anne Boleyn went underway. And was Jane stupid? No. One doesn't have to be educated to observe the school of hard knocks within royal walls. She was smart enough to know to appear meek and quiet; frankly, she sacrificed a great deal for both her ambition and the happiness of others.
This is a very poorly written ramble produced by a girl who has to use the necessary.
