Mary Adelaide is one of my favorite Royals.

I think Delphine was hoping for more than just two appearances a year with her half siblings. I think she was hoping for the Bank of Albert and Phillipe to give her money or a residence or something. I also think she wants to be seen as being equal to her half siblings and be treated as an equal by them. She seems to have forgotten the real pain she caused Paola and how that hurt filtered through to the rest of the family. They don't talk to her in public, except for Claire, who seems to be the family's "difficult person" handler (maybe because she's married to the other headache-causer).
