The R oyal Family appeared ready to 'break the tension' during the Coronation rehearsal.
The Princess of Wales in particular appeared determined to make sure the weekend passes off without incident, a leading body language expert says.
Kate is in no mood to let an awkwardness get in the way, Judi James believes.
The Duchess seemed to want a drama free few days following the latest fall out, months after the publication of Prince Harry's memoir Spare.
The Duke of Sussex will attended the ceremony without wife Meghan Markle, who is to remain in America with their children Archie and Lilibet.
Experts feat Harry could be isolated but it doesn't seem like he will get a frosty reception from Kate.
Behavioural expert Judi also noted how George, Charlotte and Louis all seem ready for the event, putting it down to plenty of experience as the children grow up with many engagements.
She told the Mirror: "‘I don’t want any drama’ is a well-used line in reality TV and always comes before an event that is about to kick off.
"The royals have their own dramas recently but it looks clear from their body language at these coronation rehearsals that they are planning to ensure everything will go hitch-free.
"Kate looks very much like the ice and tension-breaker here, smiling and chatting to some of the more serious-looking staff.
"Camilla is normally the royal exhibiting the most obvious signals of anxiety and nerves but her relaxed smile and her royal wave from the car suggests she has risen above those previous feelings of tension and is prepping to enjoy the day.
"The secret to her newly-found confidence might be the young boys in the car with her. This will be a first royal outing for some of her grandsons and their excited facial expressions suggest they are seeing it as fun rather than fearful.
"William, George, Charlotte and Louis all seem to be flying in a very tight formation here, that is probably driven by levels of reliability, confidence and experience.
"Louis walks in first to keep his confidence and enjoyment levels high but close behind is the formidable-looking double act of William and George to keep a loving, watchful eye on the most playful member of the family.
"William and George are dressed identically again here and their body language looks mirrored, which does create a serious note for them.
"At the next coronation it will be George’s turn to support his father and the one after that will see George himself in lead role, making them both extra-aware of their destiny as they take a glimpse into their inevitable future .
"Charlotte is walking behind her dad and her brothers and this seems to show how much her confidence has grown. At the Jubilee she was the one checking out the choreography and policing her brothers and the way she is sucking in her lips here suggests she will be taking that role very seriously again on Saturday."
