Stanton saw that Harry was able to assert himself at the sporting event.
"In the past, Harry would be a more introverted version of himself when he was alongside Meghan and more extroverted when he was by himself, but now he seems to have found himself," Stanton told an outlet. "He has come into his own and is his own man."
"I think he has found his inner strength, previously he hasn't shown this despite his position and it looks to have shifted in a way," he explained, adding that Harry might have realized he's a "powerful person as a royal."
In previous periods of Harry's life, he struggled with being a public figure.
"They both seem confident, Harry doesn’t look nervous at all which is quite unusual, as it is usually when he is on his own that he comes across this way but he appears very confident and relaxed," the author continued.
"It seems as though something in the dynamics or the power balance of the relationship has shifted," he added.
"This industry is just so special. And you see how many women use the platform that they have and just channel it for good," Meghan said during an interview. "And I think it's more we support each other."
"It just amplifies the work, amplifies our community. I'm just thrilled to be back in it and to be able to sit in this room being such a good company tonight and also to focus so much on how it's the crossroads of entertainment meeting philanthropy," she added.
When chatting with a reporter, the Northwestern alum teased her next Archewell project.
"Things make people feel something right and feel a sense of community," the former actress revealed after being asked about the type of programs she would make with Harry.
"But we have so many exciting things on the slate," she continued. "I can't wait until we can announce them, but it's really proud of what we're creating. My husband is loving it too. It's really fun."
