Hmm, Lord Grantham isn't going as quietly as I thought. With some emotion, he asks why Matthew can't benefit from Lavinia's father. Matthew explains his reasoning, concluding that if he took the money after having broken Lavinia's heart, he'd be "no better than a common criminal." Once again Matthew, I must ask you to get over yourself without delay. Lord Grantham is like, well, if that's how you feel, fine... but I kind of wish I'd opened something cheaper now. Then Anna enters and gives the boys a much-needed excuse to clear out of there.
So Mrs. Patmore confirms what Mrs. Hughes apparently feared: she's got a lump in her breast. Mrs. Hughes says she doesn't know what she's going to do, but Mrs. Patmore, having learned a thing or two about delaying doctor visits, tells her in no uncertain terms that she's going to make an appointment and get it checked out posthaste. Mrs. Hughes is uncharacteristically but understandably messy about the whole thing, but Mrs. Patmore assures her that she'll be there with her any time she's wanted. Mrs. Hughes wonders about the expense, but Mrs. Patmore's got that one covered too: "If you must pay money, better to a doctor than an undertaker." Mrs. Hughes can't help but laugh at that one...
...and then it's the next morning, and Anna is taking in a tray for Mary and Matthew, still in bed together. Matthew, who slept with no shirt on, murmurs that it still feels shocking for Anna to see him en deshabille, to which Anna pipes up that she's made of stern stuff. I know she's joking, but this is Matthew we're talking about. Stern stuff would have been needed if Mary had married Sir Richard. As Anna opens the curtains, Mary asks if she's seeing Bates that day, and Anna confirms that before leaving the room, whereupon Matthew and Mary agree that waking up with each other is just lovely. I hope Matthew doesn't go running off to share that with Lord Grantham, but after their conversation last night we're probably safe for the moment. The newlyweds then bicker a bit about finding a new place to live, but shut each other up with a kiss. I've seen worse strategies for marital bliss, that's for sure.
Isobel is walking in a fairly grim-looking part of some town when she passes Ethel, standing in a doorway. If I remember correctly, we last saw her refusing to let her baby's grandparents take him away from her. Ethel clearly recognizes Isobel, who passes her before having a delayed recognition of her own; unfortunately, when she turns her head, Ethel has vanished. I don't know if Ethel was actually... um, working just now, but whatever the case, you can see where this is going.
