After that frightful pre-wedding squabbling, there was good news straight away this week. The happy couple arrived back from France, which meant Matthew had survived consummating the marriage with Mary. Unaware of the risk he'd taken, he splashed out on a nice new sports car and even, on their first night back, had a go in the Downton death bed itself.
Waking up next to Mary with the carefree cocksuredness of someone who doesn't know they're lucky to be alive, Matthew apologised to Anna for being "en deshabille". Anna stayed sunny and unruffled, partly because discretion is essential for the professional housemaid, but mainly because she was relieved not to have to haul this one out by the ankles and stuff him in a cupboard.
This was a proper, old-school Downton Abbey episode, with the classic themes: sex, love, money, rivalry, and a thing only two people know about, but then they each tell someone and those people also tell someone and then people they've told tell each other that they know, and then everyone realises everyone else knows, and then Lord Grantham finds out.
Welcoming back his new son-in-law, Lord Grantham had pushed the boat out by decanting some of his best wine, presumably the 19th-century stuff. Matthew made himself comfy, knocking back the vino and calling Lord Grantham "Robert". He matter-of-factly told Robbo that yes, he was about to inherit enough money to get the Robster out of the hole he fell in when he invested everything in Titanic Cruises – sorry, I mean the Canadian railroad – but no, he was going to give it all away instead.
Bobby G was finally in the loop and took it manfully, perhaps sensing that this issue would soon rear up and ensure Matthew and Mary had the shortest honeymoon/newlywed phase since Henry VIII and Anne of Cleves. Sure enough, in virtually the next scene Mary was on at Matthew about the inheritance and he was reduced to a quiveringly ineffectual "I do love you so terribly much". Her reaction hinted that the "en deshabille" days are over, sunshine.
