Estranged royal brothers Prince Harry and Prince William have rarely attended royal engagements together in recent months.
But last June they had both put their differences aside during Queen Elizabeth II's Platinum Jubilee celebrations, which also marked Harry and Meghan's first public appearance since stepping down from the Monarchy.
Despite both brothers seeming to come together for the event, they were both seated far apart and were not seen chatting and notably kept a distance from each other at the service, which was also attended by William's wife Kate.
According to reports in the Mirror, a lip reader has revealed what he believes they said during their exchange, which included clear instructions for Kate from William.
Lip reading expert John Cassidy believes as they emerged onto the steps, Kate remarked on the service saying: "It went very well, very well" with William replying: "Yes, perfect."
Afterwards, William could be seen waving to the crowd saying hello, and Mr Cassidy says the prince then turned to Kate and said: "Wait for that to move, then we can go."
Meanwhile, a body language expert who looked at the couples at the same event believes William gave Harry the "opposite of an acknowledgement" and a "barrier gesture".
Body language expert Judi James told the Mirror that William adopted a "barrier gesture" as he and his wife Kate, now the Princess of Wales, walked past the pew where his brother sat on the way to his seat.
Judi explained: "Harry looked firmly resigned to the back row here and was not sitting behind his brother as he was for the last service of remembrance.
"Harry’s expression did suggest some relief as he joked with Zara as he searched for his car on the way out and he threw a wide, open-mouthed grin in her direction from the pews, but otherwise he fell into a haunted eye expression with some rapid blinking to suggest inner anxiety, leaning in and down to Meghan when she spoke as though keen to get some support.
"There was the opposite to an acknowledgement from William as he walked past Harry’s row during the parade out of the service.
"Sucking in his lips and with his chin pulled up in a gesture of resolve he appeared to turn his head in the other direction for a moment, raising his order of service high in a barrier gesture."
Following the Jubilee last summer in celebration of Britain's longest-reigning monarch, William and Harry were forced together just months later after the death of their late grandmother the Queen.
The brothers even joined together with their wives Kate and Meghan to carry out a joint walkabout in Windsor to look at floral tributes.
But despite the seeming temporary truce, it appears their bond has further deteriorated following Prince Harry and Meghan's Netflix series which made damaging allegations towards the monarchy and Harry's blistering memoir directed at his family members.
