That was the perfect ending, quite possibly. I admit a tear of happiness came to my eye (the left) when 'mouldy voldy' lay there on the ground, dead. And then more tears of happiness (from the right) when Dumbledore cried (tears of happiness from BOTH of his portrait eyes).
Ahaha, and they have CHILDREN!!
(On a totally unrelated note, if the weather stays like this until the sun goes down tonight, this will be the SECOND day of sun in almost two months.)
