The Duke of Sussex reached out to both Prince William and the Princess upon hearing about her preventive chemotherapy regimen.
The Duchess of Sussex has also been in contact with the Prince and Princess following reports that the Sussexes were caught off guard by the Princess's revelation, which they only learned about recently.
An insider revealed that they were unaware of the situation until it became public knowledge, highlighting the significant damage caused to their trust and their distancing from the royal family.
Sources close to the Sussexes did not provide details on how or when the couple learned about the diagnosis, suggesting that the Prince and Princess likely kept the news confidential within their inner circle to shield their children.
The rift between the senior members of the Royal family and the Duke and Duchess deepened due to the couple's public appearances and disclosures, leading to a sense of caution in communication.
The intimate details shared by the Duke of Sussex in his memoir, "Spare,” particularly upset the Prince of Wales for the portrayal of his wife and the breach of trust for personal gain.
The lack of communication between the two couples for an extended period might see the recent messages from California as a potential olive branch for reconciliation.
The Sussexes' public statement extending good wishes to the Prince and Princess, after the news broke, hinted at a desire for privacy and healing for the family.
Prince Harry's swift response to his father's cancer diagnosis by flying to the UK for a meeting highlighted a possible thaw in their strained relationship.
The Duke's upcoming visit to the UK in May, without his family due to safety concerns, may present an opportunity to mend fences with his brother and sister-in-law.
Despite dropping the demand for an apology post his memoir's publication, Prince Harry's gestures of support following health news could pave the way for reconciliation, contingent on the Prince of Wales' willingness to forgive and move forward.
While the Princess may play a role in bridging the gap between the brothers, it ultimately rests on the Prince of Wales to navigate the delicate balance of family dynamics amidst existing tensions.
