1514 January to June
The year started out with Prince Hal's birthday (held on the 10th so it was a separate event from Christmas/New Years celebrations). At three years, he was already fluent in English and Spanish. He seemed to have a talent for languages, already he was trying to speak French (from courtiers and his father), His parents decided to add Latin and then Welsh when it turned out the young priest was from Wales and English was his second language - Latin his third. Other languages would follow as the child grew.
February was when Henry began openly complaining about "your relations" in conversations with Katherine. He spoke of ending his sister's engagement to the still-underage Charles on the continent. Katherine listened carefully and realized that he was serious this time. He was convincing himself that a French alliance was better for England. That meant the Queen must tell Mary what her brother was thinking - if it were presented to her the way Henry was doing now, Mary would put up a fight. She'd seen Mary angry and the girl was a match for her brother in that department. Henry's apparent delight in his father-in-law's ill health, conveyed by letters from Spain, troubled her more. For all his mass attendance, church attendance and charitable acts, Henry was veering away from the good Catholic he had been and been corrupted by secular men - craving power through him - speaking poison in his ears. Wolsey was the worst; he abused his position in the church and had gotten power from the King. Katherine thought him no more a priest and Holy Father than her maid-of-honor Bessie Blount (she had arrived a year earlier and seemed more interested in flirting than aiding her mistress). Wolsey was corrupt in both his physical and his spiritual centers.
March was when things began to feel unsettling to Katherine. Henry was in the process of 'diplomatically' breaking his sister's engagement and simultaneously negotiating terms with Louis XII for a marriage to the French King. His discussions with Louis had progressed to the point that Henry, over both his sister's and wife's objections had ordered Mary's trousseau to be created. And the Queen felt ill all the time. Mary, on the other, was besieging her brother. She wanted a concession before she would consent. It was late April before Mary got her concession from Henry. He agreed that she could pick her second husband. And so, on 9 May, Mary had a proxy wedding, with the Duc du Loungueville followed by a proxy 'consummation' that consisted of the touching of the legs on a 'marriage' bed.
June was a month of preparation and concern. Preparation for the upcoming trip to France, selections of who would go to France with Mary; Katherine was still feeling ill, she'd realized she was pregnant at the beginning of the month which caused her concern - she'd never been ill for this long before.
