Members of the royal family came together at Westminster Abbey on Thursday to mark the 80th anniversary of VE Day.

King Charles attended the event along with several other royals, including the Prince and Princess of Wales, who watched from the royal box, Queen Camilla, the Duke and Duchess of Edinburgh, and the Duke and Duchess of Gloucester.

Most of the ceremony went smoothly, but a lip reader shared an interesting moment when it looked like Charles might have gotten upset.

Lip reading expert Jeremy Freeman caught a specific exchange between Charles and Queen Camilla that caught people’s attention.

According to Jeremy, Charles showed his frustration about not being properly introduced to the veterans while greeting them.

“Unbelievable, where are my introductions?” he reportedly said, according to a lip reader who spoke to the Scottish Daily Express.

He then turned his head just as a royal officer hurried over, and he asked, “Where, where are you?”

A man then quickly joined him while Charles continued shaking hands with the veterans.
