desertrose, interesting info. At least he lives closer to Gabriella and their daughter now.
It seems like they were a couple this spring. They were together at their great-aunt Alix of Ligne's funeral earlier this year. He was named as her fiance in the list of guests for GD Jean's funeral.

And I believe that they had some probably longer, but unserious fling that stupidly resulted in a baby. Now they're thrown together, because they're super catholic and all and it can't be what is. And off they're for damage control. Well you get the picture.
I wouldn't be surprised if you were right. I hope they learn to co-parent in an healthy manner if they don't want to be couple anymore.
