It's not just a matter of it being at odds with the behaviour I'd expect of the man - although it is to some extent. It's the other factors involved.
I also wouldn't be expecting the Palace to be so strident in their denials unless they truly knew there wasn't a case. They are going much further than they need to - and their job above all else is to protect the Queen. Her Majesty might not throw her son to the wolves (although if he actually did something like this, I wouldn't honestly put it past her) but the courtiers certainly would if they thought it was needed.
That was said about Harry as well. Yet he was photographed naked with a naked young woman using him as a shield in Las Vegas.
At the time there was talk about ,”where were his minders?”
you are frightfully naive.
“I also wouldn’t be expecting the Palace to be so strident in their denials unless they truly knew there wasn’t a case.”
Don’t know anything about this case, but when I read your comment I thought of Clinton’s very public denial of Monica..
