This has become a potential movie-in-a movie. First they create this fanciful reality production, then the Terrible Two spend the second half of the film trying to extinguish the fire they themselves have started.
If Harry succeeds in killing both projects, the Netflix series and the book, it would be funny if Charles decides hes still not going to bestow royal titles onto their two children because both Camilla and William dont want it to happen.
They “didn’t want to be Royal” so remove all their titles and take them out of Line of Succession. Problem solved.
