King Charles, who has become increasingly reliant on the Duke and Duchess of Edinburgh, got a flood of bad news on Thursday.
Duchess Sophie has frequently been referred to as the monarch's "secret weapon" while the royal family faces enormous issues.
As the senior members were preparing to reconvene for the King's Foundation's annual award presentation, Charles learned of the fatal shooting at a school in Graz, Austria.
Just hours after the King's announcement, it was announced that a London-bound airplane crashed in Ahmedabad, India, killing 169 Indian people, 53 UK nationals, seven Portuguese nationals, one Canadian, and a crew of 12.
As the royal family dealt with the shock of the tragedy, the Palace depended on Duchess Sophie to go on with her obligations as a statement announcing her newest engagement was made.
