• Scandal rocks Downton when Lady Cora opens a door for herself.
• Anna and Bates stare lovingly at each other for a solid 45 minutes.
• Hugh Bonneville (Lord Grantham) will leave the series halfway through the season, wanting to move on to other roles. Fortunately, since British lords have the ability to “regenerate,” another actor can step into the role. Bonneville is actually the tenth actor to portray Grantham; he’ll be replaced by The Thick Of It star Peter Capaldi.
• Daisy leaves Downton and is replaced with a cartoon mouse. Few notice.
As a Brit, and someone who had seen series 4, I can confirm all of these spoilers as true.
