From an article:
“I looked at Willy, really looked at him, perhaps for the first time since we were little, taking in every detail: his familiar scowl, which had always been the norm in his dealings with me,” Harry wrote, adding that William’s baldness was “alarming” and more “advanced than mine.” He also thought that William’s resemblance to their mother, Princess Diana, had “faded.”
“My dear brother, my archenemy, how did we come to this?” he allegedly wrote. “I felt overwhelming tiredness. I wanted to go home.”
