Mary’s Commitment To Her Upcoming Marriage Will be Tested
As Mary’s upcoming wedding looms, a terrible tragedy pushes Mary and Darnley apart, forcing Mary to enlist in Catherine’s help. Elizabeth encounters a traitor to Spain, who petitions her to support an expedition to the New World.
Over the coming week, guests will be arriving from across the continent to witness Queen Mary and Lord Darnley's Catholic wedding, and few are as important as Lucrezia de' Medici. She lends legitimacy and strength both to Queen Mary's Scottish rule and their joint claims to the English Throne.
However, after Lord Darnley jokingly insulted King Francis, Lucrezia withdrew her support and set sail for the following day back to Florence, Italy. Queen Mary was very upset over this. Because if the Duchess goes, she takes her support and the promise of funding with her. She agreed to reconsider if she was given the lands belonging to Lord Theodore Davies. The lands are quite valuable, and come with a title, The Earldom of Menteith. And only with this exchange would she willing to continue supporting Mary's rule.
Unbeknown to Lucrezia, Lord Bothwell insured the papers by offering Lord Theodore Davies his choice of five of Bothwell's favourite horses, on top of Queen Mary's offer.
