세습무 (세습무, *seseup-mu*) refers to a shaman whose role is passed down through the family bloodline, unlike 강신무 (*gangsin-mu*), who receives the gift through a divine calling or illness. Hwa-pyeong's grandfather is alarmed that a 영매 (*yeongmae*, spirit medium) has appeared in a family that belongs to the hereditary tradition — it's seen as a breach of the natural order, like a priest's child suddenly becoming a prophet.
굿 (*gut*) is a full shamanistic ritual performed by a 무당 (*mudang*, shaman) to communicate with spirits, drive out bad ones, or appease the dead. It typically involves drumming, chanting, elaborate costumes, and offerings of food and alcohol. Hwa-pyeong is urging the shaman Yuk-gwang to perform one right now because he believes the suspect is genuinely possessed — not mentally ill.
삼도천 (*Samdo-cheon*) is the river of the dead in Korean Buddhist belief — crossing it means you have died. 요단강 (*Yodan-gang*) is the Korean name for the River Jordan, used by Christians as a metaphor for the boundary between life and death. Yuk-gwang, a shaman, casually stacks both afterlife rivers to describe how close he came to dying — a comic but telling sign of Korea's religious blending.
Father Han is citing Canon Law Article 1172, the Catholic Church's rule that a solemn exorcism (*장엄 구마 예식*, *jangeum guma yesik*) requires specific approval from a bishop — it cannot just be performed on the spot. The fact that he's about to do it anyway, without diocesan permission, signals how seriously he's taking the threat.
Catholic exorcism theology, as depicted here, holds that prolonged contact with demonic forces gradually erodes the exorcist's own spirit. Father Han's warning to Mateo isn't just dramatic — it reflects a real practice in which the Church rotates exorcists and requires them to go to confession frequently, precisely because the ritual is considered spiritually dangerous for the person performing it.
수목장 (*sumokjang*) is a type of eco-burial in which cremated remains are scattered around or interred beneath a designated tree in a church- or city-managed woodland. It has become popular in South Korea as a gentler alternative to traditional cemetery plots. The senior priest points out that Father Han cannot receive even this modest burial — because the Church does not permit sacred ground or rites for suicide.
조폭 (*jopok*) is the everyday Korean shorthand for 조직폭력배 (*jojik-poknyeokbae*), organized crime figures or gangsters. Detective Bong-sang is listing the worst people he's faced in his career to underscore how unsettling the suspect is by comparison — even hardened criminals with known motives feel more normal to him than this man.
Historically the Catholic Church denied funeral rites and consecrated burial to those who died by suicide. While official doctrine softened in recent decades — recognizing that mental illness or extreme duress reduces culpability — many older Korean clergy still apply the strict traditional position. The senior priest's blunt reaction reflects that older generational view within the Korean Church.
The small metal bells called 방울 (*bangul*) are among the core tools a Korean shaman uses during ritual. Their ringing is believed to attract benevolent spirits and drive away harmful ones, much like incense clears a space in other traditions. Yuk-gwang shaking them inside a police holding room is a jarring collision of sacred folk practice and modern institutional space.
