A scene from “Unfinished Business”

Princess Alice: One of the few joys of being as old as we both are is that it's not our problem. It's not really our country, either.

Louis Mountbatten: What are you talking about? Of course it's our country.

Princess Alice: We Battenbergs have no country. Our family might have kings and queens in its ranks, but we're mongrels, too. Part-German, part-Greek, part-nowhere at all.

Louis Mountbatten: Well, this is my country. It gave me a home, it gave me a name, and in return, I've given it my life. And to see it like this breaks my heart.
