“Maybe this is a sign that the family are listening.”

Prince William recently opened up about his late mother, Princess Diana, and brother Prince Harry in ITV documentary, Prince William: We Can End Homelessness. According to one royal expert, the Prince of Wales’ comments could be interpreted as a positive sign when it comes to the Duke of Sussex’s relationship with the Royal Family.

In the documentary, William reflected on Diana’s charity work, which included taking her sons to visit homelessness organization The Passage. “She took Harry and I both there,” William explained. “I must have been about 11, I think, probably, at the time. Maybe 10. I’d never been to anything like that before. And I was a bit anxious as to what to expect.”

Journalist Richard Kay, who was a friend of Princess Diana’s according to the Express, told the outlet, “Well, you could easily take that latter view that he can’t not mention [Harry’s name]. How could he separate Harry and him from something which his mother took them both to?”

Kay continued, “But I think there is something calculated and I think it is an olive branch.”

It’s impossible to know whether William had any particular motives in mentioning his brother in the new documentary. However, Kay suggested “maybe this is a sign that the family are listening,” and could eventually reunite.

Discussing his earliest visit to The Passage, William said in the ITV documentary, “My mother went about her usual part of making everyone feel relaxed, and having a laugh and joking with everyone.” He continued, “I remember at the time, kind of thinking, well, if everyone’s not got a home, they’re all going to be really sad.”

William was also struck by “how happy an environment” there was at the London-based organization.

“I remember having some good conversations—just playing chess and chatting,” William said of the visit. “That’s when it dawned on me that there are other people out there who don’t have the same life as you do.”

Prince William was so impacted by his mother that he went on to become the royal patron of The Passage.

“I feel, with my position and my platform, I should be delivering change,” William explained in the documentary. “I’ve spent enough time learning and listening to what people have been through that I feel almost guilty every time I leave that I’m not doing more to help.”
