세습무 (seseupmu) refers to a family that passes down shamanic practice from parent to child across generations. The grandfather's alarm at the word 영매 (yeongmae, 'medium' or 'vessel for spirits') makes sense here — in his world, spiritual gifts are supposed to stay inside a recognised lineage and be controlled, not appear unpredictably in a grandchild.
육광 uses the word 자결 (jagyeol), which literally means to end one's own life by one's own decision. In Korean folk-spiritual belief, a possessed person dying while the spirit is inside forces the spirit to be trapped or expelled — it is framed here not as despair but as a tactical act of sacrifice within shamanistic logic.
길영's surprise that a Catholic priest drinks well reflects a common Korean assumption that clergy lead strictly ascetic lives. In practice, sharing 소주 (soju) or 막걸리 (makgeolli) at a pojangmacha is a normal part of Korean social bonding, and the moment where a priest joins in signals that the three characters are finally just people together, not roles.
Korean has two main speech levels: 존댓말 (jondaemal), polite formal speech, and 반말 (banmal), plain casual speech. 길영 has been speaking to 최윤 in 반말 the whole series despite him being a priest, while 최윤 has maintained 존댓말 out of respect. Her joke — 'if you're so bothered, just speak casually too' — is an invitation to drop the social distance that has separated them.
화평 pours 소주 (soju) into the sea for 육광. Offering food and drink at the place where someone died or is missing is a widespread Korean practice rooted in both Confucian ancestral-rite tradition (제사, jesa) and shamanistic belief — the spirit needs to be fed and acknowledged so it can rest. Bringing raw fish (회, hoe) because 육광 craved it makes the gesture intensely personal.
눌림굿 (nullimgut) is a shamanistic ceremony performed to suppress or block a spirit's influence — literally to 'press it down.' 박일도 explains that after 화평 underwent this ritual as a child, he lost the ability to see the demon clearly. 굿 (gut) is the general term for Korean shamanic ritual; different types target different spiritual problems.
박일도 reveals that 박홍주, the sitting lawmaker, willingly collaborated — not through possession but through ambition. In Korean dramas and public discourse, the 'politician who makes a pact with evil for power' trope often reflects real anxieties about chaebol-linked or factionally corrupt politicians. The show ties supernatural horror directly to the machinery of Korean electoral politics.
화평 has cut shamanistic scripture (경, gyeong) directly into his own flesh as a containment seal. Carving or writing sacred texts on the body to trap or ward off spirits appears in both Korean folk-shamanistic tradition and broader East Asian esoteric practice. The act echoes the physical exorcism tools used earlier in the series — ritual objects, holy water, prayer — but here the body itself becomes the vessel and the lock.
박일도 lists historical identities it has worn: 김사다함 is a real Silla-era warrior famed for a tragic early death; 선묘 is the Buddhist nun from Silla legend who transformed into a dragon for love; 아리나발마 and 생치새 are more obscure archaic names. By claiming these figures, the demon presents itself as woven into the fabric of Korean history itself, older than any single religion.
원내 대표 (wonnaedaepyo) is the floor leader of a political party in the National Assembly — the most powerful party position in parliament, outranking ordinary lawmakers. 봉상's horrified reaction to the news that 박홍주 has reached this level is the show's dark punchline: the person 박일도 groomed for power is now one step closer to the presidency.
화평's closing narration calls the entity 손 (son, 'hand'), the name used throughout the series for 박일도's form when it travels through the sea. In Korean shamanistic belief, evil spirits are not destroyed — they are expelled, contained, or temporarily driven off. The warning that 손 will return 'from the eastern sea' when the world grows corrupt is consistent with the idea that this evil is cyclical, not defeated.
