A rift between the princes has been widely reported since 2018, but Saturday's reunion suggests that the pair may have set aside their differences.
Prince Harry and Prince William were intentionally separated in the funeral procession

Ahead of the funeral, Buckingham Palace spokesperson told People in a statement that this was "a practical change rather than sending a signal."
"This is a funeral and we are not going to be drawn into perceptions of drama," the spokesperson added. "The arrangements have been agreed and represent Her Majesty's wishes."

The funeral procession began at the State Entrance at Windsor Castle and ended at St George's Chapel.
Members of the funeral procession stood in formation outside the chapel, staying socially distant. Phillips, Queen Elizabeth II's eldest grandchild, remained standing between William and Harry.

Footage of Philip's funeral service showed William and Harry sitting in different sections of St George's Chapel. William sat next to the Duchess of Cambridge, Kate Middleton, while Harry sat alone in a different pew.
William and Harry were seen together after the funeral - a potential sign of reconciliation
Video footage taken after the funeral showed William and Harry walking closely alongside one another and chatting with Kate Middleton. NBC captured footage of the conversation (which cannot be heard) in a video, and TODAY shared it to Twitter.
A source told Vanity Fair in November 2018 that another reason could be "Harry felt William wasn't rolling out the red carpet for Meghan and told him so."
The rift between the brothers had only seemed to grow since Harry stepped back from his royal duties in January 2020, but it appears that the princes' shared loss of their grandfather may be bringing them back together.
