Matthew’s mother Isobel felt that the entire thing was silly and seemed to be on the verge of sending Sybil the money herself. “I suppose you agree with Robert,” she commented to Robert’s mother Violet. “Then not for the first time, you suppose wrongly,” Violet snapped. Yay for Maggie Smith being back as the sharp-tongued Dowager Countess!
But soon, pregnant Sybil and her husband Tom arrived. "Please tell me you sent the money," Sybil says to her father, Robert, but he was nonplussed; he’d done no such thing. (In a truly touching later development, it was revealed that Violet had sent the money to enable them to make the trip.)
But not everyone was happy Tom was there, and during one dinner, a snobby neighbor named Larry Grey slipped something into Tom’s drink that made the Irishman act drunk and start loudly spouting his politics. When caught, Larry couldn’t see what the fuss was all about. “He’s only a grubby little chauffeur,” he remarked. Robert, Larry’s father, Lord Merton, and Matthew all stood simultaneously, ready to defend Tom, but it was Matthew who went over to Tom and announced that his future brother-in-law would be his best man as well.
And even more drama was brewing before the actual wedding between Matthew and Mary could take place. Robert went up to London to look into financial matters and discovered that railway investments he’d made before the war had gone badly and wiped out most of his wife Cora’s fortune. If something didn’t happen to save them, the Crawley family would have to give up Downton Abbey.
