McLean asked, “Why do you feel a bit of sympathy for her? Just because of the Queen’s passing or because of her relationship with the royal family?”

“I guess both. It was quite nice to see William and Kate and Meghan and Harry together,” she said. “I just wanted to show her that she’s welcome here and wanted to hug her after everything that’s happened.”

Dressed in black, the foursome spoke with onlookers and toured the emotional tributes left for the late monarch, whodied Thursday at age 96.

Another source adds that security was not expecting both couples at the walkabout.

Prince Williamthought the walkabout to greet the crowds “was an important show of unity at an incredibly difficult time for the family,” a royal source tells PEOPLE.

A palace insider tells PEOPLE: “It’s such an extraordinary historical moment and also a deeply personal one for the family that you’d hope and think that all members of the family would unite and support [the King] especially. And perhaps some of those wounds can be healed in the process.”
