That smile is all Mary!
Christian has become a handsome young man, I still think of him as the little attendant at Vic and Dan's wedding! I think he has matured a lot (not just in appearance but in personality) since his grandfather's death. I don't know why but his bearing and pose at his grandfather's funeral was remarkably mature and made me realise for the first time that he is no longer that little boy in a sailor suit.
Being a teenager is a difficult enough period anyway, but the daunting thought of his future role must be hard for him to reconcile. I hope that he is inspired and helped by other royal heirs, I think Godmother Vikkan will be a great influence, and I hope his contemporaries like Elisabeth, Amalia and IA help form a strong support network, continuing the tradition of closeness between these royal families. It is amazing how many royal heirs are female too, so hopefully Christian will be helpfully influenced by women other than/in replace of his mother.
I really wish him the very happiest of birthdays, and I hope that many more is to come! Though he resembles Mary most to me, I see flashes of Fred and even Margrethe too.
