Lord and Lady Grantham
When World War I began, Cora (Elizabeth McGovern) and Robert (Hugh Bonneville) reluctantly converted Downton Abbey into a convalescent home. While Cora discovered strength in managing the war effort, military veteran Robert grew increasingly frustrated that he couldn't report for active service and began a flirtation with the new housemaid Jane (Clare Calbraith). Before the relationship went too far, Jane resigned and left Downton. As Lady Grantham fell to Spanish flu, nearly dying, Lord Grantham realized the error of his ways, and the heads of the Crawley family finished season 2 on a peaceful note.
