Prince Harry made a whistlestop tour back to the UK to witness his dad being officially crowned as the new King before making a swift return to the US following the Westminster Abbey service on Saturday.
The Duke of Sussex had been rumoured to be heading back to California after stopping over less than 24 hours, with the historical day for the Royals also falling on his son Prince Archie's fourth birthday.
But despite his hectic dash back home from Heathrow airport, the ex-working Royal didn't leave without a special keepsake of the landmark event.
According to reports in the Mirror, Harry was seen leaving the lavish ceremony in London clutching an Order of Service as he made his way to the airport.
An Order of Service is a printed guide to the ceremony, a 50-page booklet outlining the structure and content of the event, as well as all the hymns and prayers used during the historic ceremony - a touching keepsake from his father's big day to take back to his family.
Harry's attendance at his dad's Coronation symbolised a small show of unity with the Royal Family after he and Meghan Markle strained the relationship near breaking point with bombshell claims and allegations towards the monarchy.
The Duchess of Sussex had decided to stay in their California home for the event with their two children, Prince Archie and Princess Lilibet.
But now Royal fans could be speculating that Harry's decision to take the memorabilia from the service could be a heartfelt gesture of affection and respect for his father.
During the historic Coronation yesterday, which saw thousands of fans line the streets of London, body language expert Judi James observed Prince Harry returned as a "joker" as he was seen mimicking his cousin Eugenie's heavily pregnant state in his arrival.
His action at the entrance of Westminster Abbey made Eugenie and her husband Jack Brooksbank laugh, as the Duke then used his body language to display a confident and upbeat approach as he made his way up the aisle.
Ms James noted that Harry arrived with his cousins Beatrice and Eugenie, who have "remained friends despite the rifts in the royal family."
She told the Mirror: "Chatting first to Edo he then got the attention of Eugenie and Jack and we saw an incredible return of the joker prince as Harry grinned and used two hands cupped widely under his stomach to do what looked like a mime of Eugenie’s heavily-pregnant state."
After chatting with Eugenie and Jack, Harry fell back to face the music alone as he entered, although he continued to display his confident and happy demeanour as he made his way up the aisle, nodding, grinning, and chatting with people in the congregation.
Ms James added: "Still smiling and with his cheeks rounded, he then proceeded to perform a display of what looked like rather cocky bravado.
"His striding walk looked jaunty as he pushed one side of his jacket away before making his way up the aisle nodding, grinning, using eye-brow flash rituals and chatting with people in the congregation as though signalling to the world that he was upbeat, confident and happy to be back."
