: Yes she sat in the third row next to her : husband. Of course she could have been : seated on the second row but than her : husband would have been placed behind : instead of next to her and that might not be : what the couple want.
It would not be correct to seat Princess Elisabeth in the same row as Prince Joachim, because rank-wise she should not sit in front of Princess Benedikte. But Princess Elisabeth never sits with the other royals in the royal box anyway, so it would have been quite a surprise if she suddenly appeared there. The only exception I remember took place some months ago during a concert in Fredensborg Palace Church. Here the princess sat in the royal box. Her brothers did not attend that event. Here is photo of Elisabeth taken today. By the way, her two eldest nieces told on televions today that they were grateful to their aunt for picking up the bill for the dresses they wore yesterday.
