강무 mentions hitting six newspapers and two broadcasters. In 1987 Seoul, the major dailies (조선일보, 동아일보, 한국일보, etc.) and the two state-linked TV networks (KBS, MBC) were the only mass-media gatekeepers — which is exactly why leaking to all of them at once was the only way to guarantee a story couldn't be buried.
임지록's title, 통전부장, means head of the United Front Department (통일전선부). This real North Korean agency runs covert operations targeting South Korea — espionage, influence operations, and managing agents abroad — making it the organ directly responsible for everything the agents in this drama have been doing.
비자금 literally means 'secret funds' — an off-the-books slush fund kept outside official accounting. In the authoritarian governments of the 1980s, these pools of cash were routinely used to finance election operations, bribe officials, and run clandestine projects that could never appear in any budget line.
재밍 is the Korean borrowing of 'jamming' — broadcasting interference signals to block radio communication in and out of an area. 경희's objection is practical: their own informant (프락치, a planted spy) inside the dormitory would also be cut off, leaving the outside team blind to what is happening inside.
컵라면 (cup ramyeon) is the ubiquitous Korean instant noodle in a foam or paper cup — just add boiling water. By 1987 it was already a staple emergency snack sold everywhere from corner stores to university canteens, so one cup being the only thing 영로 has eaten all day instantly signals how dire the siege conditions have become.
천령 도사 is a 무속인 (mudang-type shaman or fortune-teller). 공수 means a divine message channelled through the shaman, and 점괘 is a divination reading — here drawn by picking a card. Consulting a 도사 before major decisions was common among well-off conservative families in 1980s Korea, and the scene shows even powerful women like 성심 and 애라hedging their bets with supernatural guidance.
강무 uses the phrase 괴뢰 정권 — literally 'puppet regime' — the standard South Korean government term for the North Korean state in this era. Throwing it back at 남태일, who is secretly cooperating with that same government, is a pointed irony: the hardline anti-communist is himself colluding with the enemy he publicly denounces.
The flashback depicts a brutal culling exercise at what appears to be a remote training camp (북수백산 references a mountainous northern region). The practice of forcing trainees to fight or eliminate each other to produce a small number of 'elite survivors' reflects documented accounts of how North Korea's clandestine service shaped absolute loyalty — or broke those whose loyalty was conditional.
청야 names the condition in English-derived Korean: PTSD, then glosses it herself as 외상 후 스트레스 장애 (post-traumatic stress disorder). Her surprise that someone with such fragile mental defences could have been a covert operative reflects how both North and South Korean security culture of the era dismissed psychological trauma as weakness rather than treating it as a medical reality.
The TV anchor immediately reports that 은창수 was shot by 'armed spies' — not by his own operation unravelling. This is a live demonstration of the media-management the characters have been fighting all episode: state-adjacent broadcasters in 1987 South Korea routinely shaped breaking news to protect government institutions, turning official failures into heroic narratives before any independent reporting could emerge.
