Kate Middleton was missing in action for a lot of this year, which caused major concerns among people. People were shocked when the Princess of Wales revealed why she had been out of action.

Now, it seems like she decided to come back, but people have noticed one massive detail that has still sparked questions.

On Sunday, Prince William was with his son Prince George to watch the Euro Final in Berlin, Germany. At the same time, Princess Kate and Princess Charlotte were in London for the Wimbledon final.

The 42-year-old was seen talking to his son alongside UEFA President Aleksander Ceferin and Felipe VI, the King of Spain. At one point, William was seen bending down to George’s level to discuss a moment of the game, which England lost at 2-1.

Despite the English defeat, William and George kept their expressions neutral and graciously accepted their team’s defeat. While the pair were enjoying the Euro Final, William’s better half, Kate, 42, was attending the Wimbledon final with their daughter Charlotte. This was a significant moment as Kate has not been seen in public since she announced her cancer diagnosis in March this year.

Kate, is the patron of the All England Lawn Tennis Club watched the final as Carlos Alcaraz of Spain defeated Serbia’s legend Novak Djokovic. Middleton’s little sister Pippa Middleton also accompanied the two royal ladies.

To mark the momentous occasion of her return to her royal duties, Kate took to social media to make a post. Her post read, “Great to be back at @Wimbledon!,” it went on, “There’s nothing quite like The Championships 🎾.”

Middleton also attended the championship last year, alongside William and their two older children.

People, however, were quick to notice that given this was Kate’s first public appearance after announcing his cancer diagnosis, she was interesting without her husband. An X user wondered whether the two of them were leading separate lives at this point since they had not been seen together for a while.

Another user wrote, “That women never had cancer. That family is actually sick for using that to disguise the marital issues her and her husband are having causing them to do their own seperate engagement. It’s sick.”

It seems some people took issue with William not being by his wife’s side as she made her first public appearance.
