Elizabeth opens Supper at Six announcing a lesson on ionic, covalent, and hydrogen bonds, using relatable analogies to marriages, parties, and “love at first sight.” She transitions seamlessly into cooking chicken pot pie, tying each step to chemical principles. At-home viewers react, applying her framing to their own relationships.

Behind the scenes, Walter Pine reels: he secured a contract extension only by promising less science and more sex appeal, which Elizabeth rejects. He also dreads his daughter Amanda’s family-tree assignment that exposes her adoption. Meanwhile, Elizabeth requests extra fire extinguishers for tomorrow’s combustion episode, further unsettling Walter.

During breaks, Rosa defends Elizabeth’s precise terminology as empowering while Walter frets about sponsors, forcing “aspirin” over “acetylsalicylic acid.” Walter notices Elizabeth’s trousers, fearing executive backlash from Phil Lebensmal, as she continues to insist on safety and substantive content.

Back on air, Elizabeth explains mixtures and societal balance with “Sweden,” then emphasizes home “stability and structure.” With time remaining, she defies crew warnings to take an audience question. Mrs. George Fillis, a 38-year-old “housewife,” cites osmosis and edema and admits she once dreamed of being an open-heart surgeon; the audience erupts in support.

Elizabeth validates Mrs. Fillis’s abilities, outlines a path—library, MCATs, medical school, residency—and tests her with the molecular weight of barium chloride, which Mrs. Fillis answers correctly. Declaring “Free Day,” Elizabeth gifts her the pot pie and closes by addressing the woman’s five sons: “Boys, set the table. Your mother needs a moment to herself.”
