Prince Harry and Meghan Markle use subtle signals to communicate.

The Duke and Duchess of Sussex stepped out together on Thursday for a Remembrance service. The Sun shared a clip showing how “in tune” the couple was during the sighting.

In the video, Prince Harry slightly looks at Markle in the side of his eye and gives her a nod. Markle understands what her husband wants for her to do, so she subtly makes a little step to be an inch closer to him as they stand at Westminster Abbey’s Field of Remembrance.

During the visit, Prince Harry and Markle paid their respects to the fallen soldiers. They also laid crosses before they met the veterans.

While Markle was responsive to her husband’s subtle gesture, there were times when Prince Harry ignored her. Back in June when the couple joined the other members of the royal family on the Buckingham Palace balcony for Trooping the Colour, many noticed how Prince Harry told off his wife.

There was a video of Prince Harry looking inside the room behind them and speaking to someone off camera. Markle looks back and says something at the duke causing him to frown. Markle turns round again to her husband who appears to “tell her off.” Prince Harry maintains his stern expression as Markle tries to compose herself.

In July, the Duke and Duchess of Sussex were caught on camera when they watched a baseball game. In the clip, Markle faces Prince Harry and tells him something. However, the prince is talking to someone else, so he ignores his wife. 

In related news, many are convinced that the royal couple will give their son Archie a sibling soon. According to insiders, they have been dropping clues that they want a second child.

Just recently, Prince Harry and Markle held a coffee event for military families in Windsor and Prince William’s younger brother was heard talking about the possibilities of having another baby soon.

“Harry was really quite interested in how things were with second children, as well because we both have older children,” Susie Stringfellow, a military wife, told ITV. “We were trying to encourage him to have a second baby.”
