It is definitely water under the bridge, but as time goes by, more details regarding who actually wanted the divorce is emerging. That was inevitable. One can't hide the truth forever.
The most important part of this very public situation, due to the royal status, is that all seems to be working out in J and Alexandra's new lives and that the two children of that marriage seem to have continuity, stabiity, and happiness in their lives, no matter whether they are in Schackenborg or Copenhagen. That the four closest adults to them all get along is also of major importance. That way, the boys aren't put in the position of having to take sides, which is so often the case in divorces.
