Britain's Prince Harry has been a fervent promoter of the Invictus Games since he first initiated the event in 2014.

This year, while promoting the Invictus games at Sydney Harbor in Australia, Prince Harry caught a glimpse of a familiar face.

Daphne Dunne, a 97-year-old Australian widow remembered the young prince from their first meeting in 2015. He had just wrapped up his work with the Australian army and she was one of the locals he met near the Sydney Opera House. Back then, they exchanged warm words and a kiss on the cheek.

One day ago, the two locked eyes again and greeted each other like old friends. "He remembered me and gave me another kiss on the other side," she told NBC News.

Dunne's late husband fought in World War II and she wore his medals on her jacket at her first meeting with Prince Harry.

At the time, Harry had just finished his month-long secondment with the Australian Army. When the two first met, Dunne gave Harry a kiss on the cheek after they exchanged warm words.

This year, he returned the greeting during his promotion tour for the upcoming Invictus Games. The games are a Paralympic-style multi-sport event inspired by the prince's first visit to the Warrior Games in the United States in 2013.

He was moved by the ways in which the power of sport could help to heal the physical psychological and social traumas of wounded, injured and sick service personnel.

Here are some images from Prince Harry's first meeting with Dunne:
