It seems that the Don Giovanni plot was wrong, and Don Giovanni ends up settling down with Donna Anna after all. And they have a family,

I was at the ROH's Don Giovanni last year with the wonderful Erwin Schrott (who really looked the part, as you can see!) as the Don and Anna Netrebko as Donna Anna. The chemistry, we now know, was not just on stage.

UPDATE: Mrs P points out that the picture is not in fact of Anna Netrebko. Oops. Wrist duly slapped.
