London, UK - Today will be a highly emotional day for Prince William and Prince Harry, as the brothers jointly unveil a statue in honor of their beloved mother, Diana. It will be their first reunion since the funeral of their grandfather, Prince Philip.

It's also a good opportunity for the relationship between Harry (36) and William (39) to be mended. Things looked bleak for the brothers after Harry officially stepped down from royal duties and subsequently made accusations against the family in several tell-all interviews.

He further revealed more trauma from growing up in the spotlight during his docuseries The Me You Can't See. However, it was the accusations of racism within the royal family and how it affected his marriage that seemed to have done the most damage on both sides.

But today might be the moment to bury the hatchet for good, in honor of their late mother, Princess Diana (†36).

According to British media reports, a private meeting is also scheduled to follow the unveiling of the Diana statue, presumably to "clear the air".

Finally being able to discuss their grievances in private and face-to-face may be exactly what the two needed all along.

But is a reconciliation still possible after all that has gone on?

Royal author Robert Lacey told Britain's Hello! magazine that for that to happen, William would probably like assurances there won't be more dirty laundry aired out for the world.

"I think one of the clear things that has been lacking in this situation is a mother figure to knock their heads together," he commented.

"Friends of Diana have said to me – and I think they're right – that if Diana were alive, it wouldn't have got to this situation. So at that moment, on 1 July, perhaps it will be as if she has come back."

Appearing together on Diana's birthday could change everything for the better, Lacey believes.

"...if for that moment in time, they are united in paying homage to Diana, why not, in other ongoing moments of time, should they not be united in other ways?"
