발인 (barin) is the specific morning when a coffin leaves the home or funeral hall for burial or cremation — the final, public farewell in a traditional Korean mourning process that typically lasts three days. Missing your own sibling's 발인 is considered a profound breach of filial duty and brings deep shame, which is why Yeong-ro's desperation to leave feels so urgent and understandable to a Korean audience.
Earlier in the series, a 도사 (dosa) — a fortune-teller or spiritual master — reportedly foretold that exactly thirteen people would die. The wives are now arguing over whether the explosion fulfilled that prediction precisely. Consulting a 도사 or 무당 (shaman) for guidance during a family or national crisis was, and remains, a genuinely common private practice in Korea, cutting across class lines.
샬롯 최 (Charlotte Choi) is referenced here as a celebrated Korean fashion coordinator of the late 1980s who dressed public figures and entertainers. Name-dropping her signals that Kyung-hee's polished on-camera look is the product of serious, expensive professional styling — not accidental glamour. It's the equivalent of saying someone is dressed by a famous A-list stylist.
라이방 is the Korean pronunciation of Ray-Ban. In late-1980s Korea, imported Western brand goods were expensive, hard to obtain, and carried enormous social cachet. Wearing Ray-Bans in winter — as Eun Chang-su does here — signals power and wealth rather than practicality, which is exactly why the women in the scene find it fashionable rather than odd.
청산가리 literally means 'potassium cyanide.' North Korean agents in this era were issued cyanide capsules to swallow if captured, preventing interrogation. Su-ho invoking the name of a comrade who died this way is a reminder that the operatives' lives are considered expendable by their own side — a detail that shapes his growing distrust of the mission.
닭곰 is a slow-simmered chicken broth dish common in North Korea, similar in comfort-food status to 삼계탕 (samgyetang) in the South. Eung-cheol asking for a bowl is a quietly heartbreaking moment: it is the taste of home, the thing a sick person wants most, impossibly far away inside a besieged dormitory.
간첩죄 means 'espionage crime.' In South Korea under authoritarian rule, being charged with this — or even being related to someone charged — could destroy an entire family's livelihood, housing, and social standing. Bun-ok's sister died under investigation, her father collapsed from the shock, and Bun-ok herself has lived under that shadow ever since. It explains why she has survived by making herself invisible.
Seung-hee's fury refers to a documented pattern: during South Korea's authoritarian period, the 안기부 and its predecessor agencies sometimes tortured ordinary people into confessing to espionage they did not commit. Survivors' accounts of interrogators weeping publicly after brutalising people in private — exactly the image she describes — appeared in later truth-and-reconciliation hearings, giving this scene a painful historical grounding.
Bun-ok worked as a dormitory telephone switchboard operator, a job that in pre-digital Korea required routing every call manually and hearing fragments of countless private conversations. The role was low-status and poorly paid, treated as furniture rather than a person — which is exactly the social invisibility she erupts against in this scene. The students literally called her 닭똥집 (chicken gizzard), a crude put-down for someone considered worthless.
