This spring, Catherine, Princess of Wales, ended a long silence and rampant public speculation with a solemn video announcing her cancer diagnosis. In the final episode of DYNASTY: The Windsors’ Most Difficult Year, hosts Claire Howorth, Katie Nicholl, and Erin Vanderhoof explain why the message that accompanied her diagnosis was the most important speech of her royal career, and what it says about the Catherine we will see in the future. After a year of struggle, is the monarchy emerging into a new, calmer era? And what lessons will the Windsors take away from their brushes with ill-health and public speculation?

It’s been four years since Meghan Markle and Prince Harry walked away from their royal roles, sparking an endless stream of media attention and second-guessing in the UK. This year, the biggest headlines—from historic health challenges for Kate Middleton and King Charles III to royal banquets and honor ceremonies—have been coming from Windsor Castle and Buckingham Palace. Meanwhile, the Duke and Duchess of Sussex have been carving out their own luxurious, semi-royal, and very philanthropic path thousands of miles away, in the court of Montecito.

When King Charles III announced his cancer diagnosis in February, there was an outpouring of emotion in the UK, along with some concern about what it would look like if the monarch not wasn’t able to greet his public on a daily basis. From the beginning, the king balanced his treatments with his duties, and privately he told his medical team that attending Trooping the Colour, the parade that marks his birthday, was nonnegotiable. By the time the June celebration rolled around, the king was out on the Buckingham Palace balcony with Queen Camilla at his side, and the clouds over the Windsors’ future seemed to part.

On this week’s episode of DYNASTY: The Royal Family’s Most Challenging Year, hosts Claire Howorth, Katie Nicholl, and Erin Vanderhoof return to the unprecedented events of the year, and Charles’ embrace of radical (for royals, anyway) transparency.
