At the St. Theresa's women's clinic, Sister Mary Euphemism is cautioning Margaret and Dr. Mason about the upcoming section of the curriculum: the part where they talk about "the act itself." Margaret assures her that she will keep Dr. Mason "on the path." After Sister Euphemism exits, Mason makes a joke about how she's constantly flirting with him, causing Margaret to laugh. I like Dr. Mason. It will be very sad when some gangster or another beats him to death in the season finale. Anyway, who should show up after hours but our friend Mrs. Scherer, who requests to speak to Margaret alone. I guess she's been coming to the classes, per Margaret, so that's progress. But her more pressing concern, she tells Margaret, is that her husband won't keep off her. He did for a while, after the miscarriage, but now ... Margaret looks concerned, as Mrs. Scherer explains that she doesn't want to have any more children, ever. Margaret sees where this is going and says they're not allowed to speak of that here. "It's what every woman who comes in here wants to know," Mrs. Scherer says. Stuck between her mission and her mandate, Margaret offers to give her a pamphlet (presumably what she received from the Margaret Sanger people?), but Mrs. Scherer doesn't need a pamphlet, or man to tell her what she already knows. Ah, so she's not quite the dumb Dora she seemed at first. She tells Margaret about the day they met, her miscarriage. "I stored the milk ... I waited ... it wasn't an accident," she says. "You understand?" Margaret does. We do. Somebody at HBO wasn't so sure, though, because we get a blaringly obvious ADR line about how "I drank it on purpose to lose the baby." GOT IT. Anyway, she wants a diaphragm, but she doesn't know how to get one. She doesn't believe Dr. Mason will give it to her -- doctors don't listen to women like her. They listen to women like Margaret. She begs her to intervene on her behalf.
