The Duchess of Sussex, Meghan Markle, is reportedly on her way back to Vancouver Island Thursday evening.
Bradby even called his documentary a "long, sad farewell" by the couple.
The fact that the Sussexes didn't appear to follow any strategy and made their announcement didn't go over well with William, as Nicholl noted: "I think William feels a sense of betrayal by his brother and possibly a sense of being abandoned too".
Prince Harry is expected to join his family early next week.
"There needs to be a peace deal really soon because this is so toxic, there's so much anger and, to be honest with you at the moment it looks like it might get worse, not better".
Bradby elaborated on Harry and Meghan's announcement saying "it was, in effect, a declaration of independence".
"And I'd asked Prince Harry that, and he said, 'Climate change and mental health wellness'".
Samantha continued saying that there has been no attempt from the Duchess of Sussex to fix their family.
The meeting with Queen Elizabeth will discuss key matters like funding for Prince Harry and Meghan Markle as well as their team, which includes security and protection.
According to Marie Claire, the Queen has directed her staff to work the Sussex household and government.
After a tumultuous week the Duchess has now left Harry to deal with the fallout after they made a bombshell announcement on Wednesday that they would be ditching their duties as senior royals.
While all this was happening, Meghan was on her way to Canada where baby Archie was waiting for her.
Prince Harry and Meghan have had their wax figure separated from royal family at Madame Tussauds in London.
Reports are unconfirmed around who has been looking after the tot while his parents have been in the United Kingdom, with some stating he has been with his nanny and Meghan's mother Doria Ragland, and other reports that he has been looked after by Meghan's best friend Jessica Mulroney.
