In a speech, the Duke talked about "redefining masculinity" while the Duchess spoke "as a woman of color and as your sister." She added that "the rights of women and girls is something that's very close to my heart and a cause I've spent the majority of my life advocating for." And with that she set the tone for the rest of the tour. Each key moment after that spoke to the same thing, leaving nobody in any doubt over her mission.

As the royal couple danced out of the engagement to thumping beats, it felt like they had found their groove -- more relaxed and more engaged than I have seen during previous joint engagements. Perhaps the Duchess had also discovered the same connection with this part of the world that her husband has long enjoyed.

The Duchess also gushed about how "how happy she was being a new mom." Parenthood changes your perspective on everything and for this couple, it appears to have given them a greater sense of urgency about their work. Every time they spoke, they couldn't hold back their concern for the way many things are going in the world, while highlighting the positives.

"There comes a point when the only thing to do is to stand up to this behaviour, because it destroys people and destroys lives," the Duke said in a statement. "Put simply, it is bullying, which scares and silences people. We all know this isn't acceptable, at any level. We won't and can't believe in a world where there is no accountability for this."

While the Mail on Sunday has said it stands by its reporting, the Duchess' legal moves emphasized that she intends on being a royal who will fight for what she believes is right.

"Twenty-two years after my mother visited Angola, there are still more than 1,000 minefields in this beautiful country that remain to be cleared," he said on the road that has been built over the pathway graced by Diana. "I wonder if she was still alive whether that would still be the case. I'm pretty sure she would have seen it through."

This rare glimpse of the couple's four-month-old son Archie soon went viral -- one in particular. It showed him in his mother's arms with the elder statesman leaning in to kiss the baby's head.

Was it a good picture? Not particularly. Was it highlighting a new case? No. But the image resonated because it rang true. It felt like a genuine gesture from someone who's proved beyond doubt that women's rights matter to her greatly. What made the moment even more powerful was that she wrote her message in a local language -- Xhosa. That's not her speaking as a royal, that's her speaking as a "sister," as she put it earlier on in the tour.

One student involved in the debate, Tuni Mampame, told CNN how inspiring it was to hear that from someone who "looks like me, is as inspired as me, who possibly has the same background as me."

Rather than downplaying her very regular upbringing, the Duchess of Sussex is making a virtue of it. She's continuing to fight the battle for equality she has always fought and she's picking out elements of her life to make her more relatable. She's doing the same for the royal family because none of her in-laws have the same experience.

To connect with people in South Africa, a country she had never visited before, is no mean feat and that message has resonated around the world.

"In a world that that can seem so aggressive, confrontational, and dangerous, you should know that you have the power to change it," Meghan said during one of her final engagements in South Africa. "Because whether you're here in South Africa, at home in the UK or the US, or around the world, you actually have the power within you to change things, and that begins with how you connect to others.

Meghan has clearly demonstrated over the last 10 days how she is stepping into her role as a royal. She's owning it in the same way Diana did by engaging personally in issues she so evidently connects with.

If Harry is continuing his mother's legacy by adopting her causes, then Meghan may also be, intentionally or not, adopting her spirit.
