especially since you are implying they did eventually think/say it out loud?)
For the repeated times Caroline later said out loud she wished Fritz of Wales was dead, see my write-up of Hervey's memoirs. The Victorian editor of which also footnotes with the tale of how George and Caroline already started to try and find a way to circumvent the laws of primogeniture and let Bill of Cumberland get at least part of the Kingdom before Fritz of Wales ever came to Britain, i.e. when he was still growing up in Hannover with no chance to either please or disgust them; one of the ideas was to split up Britain and Hannover again and give one to FoW and the other to Bill. AS I recall, one of the ministers even advised G1, who was still alive at the time, that he should bring over Fritz (of Gloucester at that point, since future G2 was still Prince of Wales) to Britain within his life time or else he'd never get there the way the Prince and Crown Princess were acting.
