Of course this is conjecture on my part but it is rumored the two brothers have always had some tension. That has probably led to negative feelings toward each other for the women - when all you hear is negative you start to become negative too. There maybe some jealousy from Joachim and Marie. They certainly publicized their disdain regarding their children losing the HRH and princely titles saying things like how upset their kids are, they were traumatized, the kids at school made fun of them, it demeans them, blah, blah, blah. I personally think the Queen did the right thing and was thinking about J’s kids having normal lives. J & M were the ones upset not the kids.
