Diane de Poitiers has the ability to be a sweet kind woman and mother. However, like Catherine, she is ruthless when it comes to her son. She will do whatever it takes to make sure her son is not forgotten by history, and their places secured at court.
Diane de Poitiers and a younger Prince Henry met and became intimate before his arranged marriage to the younger Italian noble woman, Catherine de' Medici. Not long after Henry's wedding did Diane became his mistress.
Less than 10 years later, Diane gave birth to the King's first child, a son she named Sebastian, much to Catherine's dismay. However, it was not long before his wife, Catherine, gave birth to their first male heir, followed by a daughter the next year.
Two years later, Henry's father died, and he became the new King of France, making Prince Francis the new Dauphin of France. Years later, Catherine and Henry had two more sons. However, despite that, Diane and Henry still grew closer. She and Henry would occasionally drift apart, but eventually, they result in getting back together.
Henry and Diane were together when Queen Mary arrived from Scotland. They were standing beside each other, with their son Sebastian. Then matched in annoyance, Queen Catherine purposely stood in front of them.
That night at Princess Elizabeth and King Philip's wedding, Diane knew Henry might begin to stray again, as he intently watched Kenna, one of Mary’s Ladies-in-Waiting dancing in the middle of the room.
Diane over heard to her son's conversation with Queen Mary, who Sebastian was beginning to like. Once Mary left, Diane approaches her son and warned him not to get involved with the Scottish Queen as she is betrothed to his half-brother, the future King of France.
