Prince Harry's Invictus Games are in full swing in Vancouver and Whistler, Canada, and Team U.S. athletes exclusively tell PEOPLE about what the event means to them.

Prince Harry signed a mini-me version of himself during a wheelchair basketball event in Vancouver, Canada, beaming as a little boy and girl—both wearing Team USA family shirts—brought over one of the wildly popular Funko Pop figures that have immortalized everyone from Queen Elizabeth to Princess Diana in vinyl form.

Earlier this year, Meghan Markle made her return to Instagram after a five-year absence, posting her first video on her @meghan account on January 1. Now, Meghan is taking her camera behind the scenes at the Invictus Games—where she and Prince Harry made their debut as a couple, in 2017.
