I can't wait to see these two dowager empresses clash wits and one liners. Season Three of Downton Abbey commences January 6 and I for one couldn't be happier. Shirley Maclaine joins the cast as Cora's mother from Boston. And what will become of dear John Bates as he waits in jail to be hung for the murder of his bitch of a wife? Will Lady Mary and Matthew Crawley ever be happy together?
