She looks amazingly like Barbara. And amazingly young.
It's said that men remarry quickly after being widowed if their prior marriage was a happy one. That seems to be the case here. I do wish them all joy, peace, and prosperity.
Five years isn't really quickly. I'm glad he had sense enough to wait awhile so he could grieve. Lots don't do that. They marry far too soon and then it's usually a disaster.
