Prince Harry refused to be moved along by handlers while speaking with a war widow on the Sydney Harbour Bridge last week, according to People magazine.
The Duke Of Sussex scaled the Aussie landmark to raise the Invictus Games Flag along with Gwen Cherne, who lost her husband, Australian Special Forces officer Peter J Cafe to suicide last year.
The 41-year-old - an advisor for widows, veterans and families for the Department of Veterans Affairs - told People she and Harry discussed "grief and loss".
"He understood what I meant," she said of the touching moment, which has since gone viral on social media.
"When you understand loss, I think it's obvious."
Ms Cherne explained that after the pair hugged, Harry was asked to move along by his entourage - but he wasn't having it.
It was a moment Invictus Ambassador Gwen Cherne will never forget, as she spent 10 minutes talking to Prince Harry as they scaled the Sydney Harbour Bridge.
"He stopped and said, 'I'm in the middle of a conversation, and I'm not going to leave this.'"
The mother-of-three said that Harry took the time to ask questions about her story, "so he had it correct in his head".
"We were talking about my story and mental health and how difficult it is still, in our society, to talk about grief and loss and suicide," she said.
Harry and Meghan's first official royal tour together will see them touch down in New Zealand on October 28.
