It's dinnertime at Downton and when Edith lets everyone know she's going to London later in the week, Rose excitedly asks if she can come. The Dowager Countess is taken aback, as she only just got there and also was supposed to hate London, but after Rose is like, oh, my silly mother, I don't hate London at all... except yes I do, but I'm planning a surprise for her, so no one tell her that I'm going to London, which I hate and love, depending on who I'm talking to? Literally all the women other than the Dowager Countess are like, this girl is capital-T trouble and none more so than Edith, who's looking at Rose like she's something she's going to be required to dissect. Perhaps to keep an eye on her, though, Edith says she can stay with her at Rosamund's (yaaaaaaay) and when Cora asks why she's going, Edith tells her it's to see the editor, somewhat apprehensively adding they're going to discuss her piece. If he's going to chat with you in person, he's doing better than most, Edith.
Later, everyone's in the sitting room when Matthew tells Edith he's thinking of going to London too, although he could stay at his club. Edith, however, tells him Rosamund would love to have him too and besides, her instincts are telling her she's going to need all the help with Rose she can get. Rose babbles on to the Dowager Countess about how excited she is, while across the room, Branson is telling Cora that his and Matthew's plan will result in them farming a third of the estate directly and they could really use her support, as Lord Grantham will resist. Joining them, Mary mildly asks if they're drawing up battle lines and Cora sighs that "the postwar world has not been kind" to Lord Grantham, but it's pretty clear where their opinions lie at this point. Mary asks how he's finding Jarvis' cottage and Branson says it's perfectly fine, save the part where Jarvis took all the furniture with him, since he happened to own it. Mary suggests they check the attics at Downton, while Cora asks if it won't be lonely for poor baby Sybil. Branson, however, smiles that he thinks the situation is right for both of them and I suppose we can deal with him living a few stone's throws away, given that he was Liverpool-bound in the very recent past.
