What did he mean when he said that 'it is better for everyone if Edith's happy'? It just sounded rather harsh. I mean, when Edith is unhappy she keeps to herself in a corner, but when Mary is unhappy she lashes out and tries to make everyone (Edith), miserable. As shown by her behaviour in episode 8. And what about Cora? That was a rather catty remark she made about Edith's prospects. Seriously, in Series 6 they still treat her pretty much like shit. And Tom and Cora are meant to be the nice ones. Like, whereas Robert tells Mary she could rule the kingdom if she wanted (despite this being said after she completely failed to get rid of a blackmailer and consider how the truth would affect Tony and Mabel) yet all Edith got was a 'You always surprise me'. Seriously! The only nice thing her family has to say about her is 'she surprises me and the surprises are sometimes good'. Poor Edith. Imagine living in a house filled with people like that. Oh well. At least she has Bertie now. He knows how to treat her right.
