In June, Kensington Palace announced that Meghan and Prince Harry would be starting their own foundation, quitting the charity shared with Prince William and Kate.
Camilla attended the annual Royal British Legion Festival of Remembrance with her husband Prince Charles, the Queen and other members of the royal family. While Prince Harry revealed that he's on a different path than his older brother Prince William.
The Dukes of Cambridge and Sussex watched proceedings from ground-level.
The pair have also leaned on each other in hard times; earlier this year, it was reported Meghan had been going to Williams for support amid an onslaught of nasty comments on the Sussexes' social media pages.
Kate also joined the rest of her family at London's Cenotaph for the national memorial service.
This year's event marks 75 years since notable battles of 1944, including Monte Cassino, Kohima and Imphal, D-Day and the collaboration of Commonwealth and Allied forces.
It also celebrates the 100th anniversary of the Government Communications Headquarters and pay tribute to RFA Mounts Bay which delivered supplies and aid to the Bahamas after Hurricane Dorian this year.
It is believed that William did not see the interview ahead of its airing and was left "concerned" for his brother following his admission.
When asked by an ITV correspondent if he had grown distant from William, Harry said, "Part of this role and part of this job, and this family being under the pressure it's under, inevitably stuff happens. But I will always be there for him, as I know he'll always be there for me".
"It kind of goes to show you what an unbelievable person that she is, and that's just one of the many things that she does for me".
