Interpol can issue a Red Notice asking member countries to arrest and extradite a wanted person. Because Vincenzo is an Italian national who committed crimes in Italy, Korean authorities would hand him to Interpol agents rather than try him locally — which is why the show treats the arrival of Interpol as the specific threat it is.
Vincenzo calls the parting gunshot his 'appetizer' — a deliberate use of a breezy English loanword (애피타이저) to make a violent act sound casual. This kind of deadpan black humour is a signature tone of the show and lands differently for Korean viewers who catch the contrast between the friendly borrowed word and the brutal act.
Seok-do says he spent his life dreaming of being Michael Corleone from 대부 (Godfather, literally 'Godfather/Patriarch'). The 1972 film is enormously famous in Korea and 대부 has become shorthand for the archetype of a cool, calculating crime boss — which is exactly why meeting the real thing (Vincenzo) fills Seok-do with awe rather than fear.
탁발 is the practice where Buddhist monks walk through the neighbourhood carrying a bowl to receive food donations from the community. It is how small temples without wealthy patrons supplement their living expenses. The Geumga Plaza monks going out for 탁발 daily signals that their temple is genuinely struggling — a detail the residents immediately understand.
십시일반 (十匙一飯) is a Korean idiom meaning 'ten spoonfuls make one bowl of rice' — if everyone contributes a small amount, the combined result is enough. It is the go-to phrase Koreans use when rallying neighbours or colleagues to pool resources for someone in need, and it perfectly captures the mutual-aid spirit of the Geumga Plaza community.
Myung-hee's quip about getting her 'life extension' from a convenience store yoghurt is a nod to the ubiquitous small Korean yoghurt drinks — brands like Yakult or Biofil — sold at every 편의점 (convenience store) and street vendor cart. They are so ordinary and cheap that using them as a metaphor for her own modest survival is a sharply self-deprecating joke.
Han-seo mentions that Joon-woo once told him to be like Elizabeth Holmes, the founder of the blood-testing startup Theranos. Holmes became internationally infamous for massive investor fraud and was convicted in 2022. By the time this episode aired, Korean business media had covered her trial extensively, so the audience immediately understands Han-seo's point: the role model he was given was a fraud in prison — exactly where Joon-woo now sits.
The facility shown is a 구치소, a remand centre holding people who are arrested and awaiting trial or sentencing, not the 교도소 where convicted prisoners serve long terms. The distinction matters here: Joon-woo's team is confident they can get him out relatively quickly precisely because he has not been convicted yet, and the procedural rights available to remand detainees are different.
Vincenzo reveals his Italian nickname translates as 'the well-fed cat' (배부른 고양이). In Sicilian mafia culture, nicknames are taken seriously as markers of a member's reputation and method — think of real figures like 'The Boss of Bosses.' A cat that is already full will bat a mouse around for hours before killing it, making the name a precise description of his sadistic patience with enemies.
Vincenzo recounts that the man he was tormenting attempted suicide during the two years of psychological torment. He then had the man treated, released, and killed on the day of discharge. The story is told to illustrate Vincenzo's ruthlessness, but the suicide attempt is presented as a fact of the situation rather than something glorified — the show frames it as evidence of how extreme the psychological cruelty was.
Miri's mother made 고들빼기장아찌 — a pungent, slightly bitter pickled wildflower root that requires weeks of fermentation and is considered a labour of love. Paired with the 무말랭이 (chewy dried radish strips) that Hui-su pressed on him, these are the kinds of homemade 반찬 (side dishes) that Korean parents send with children leaving on long journeys — practical, preservable, and deeply affectionate.
Jeok-ha closes his farewell with 나무 관세음보살 — a devotional chant invoking Gwanseeum Bosal (Avalokiteśvara), the Bodhisattva of compassion who is believed to protect travellers and those in danger. It is the Buddhist equivalent of saying 'may God watch over you,' and hearing it from a monk at a send-off carries genuine spiritual weight for Korean viewers.
Vincenzo quotes 'a friend is a single soul dwelling in two bodies,' a line attributed to Aristotle that has circulated widely in Korean school textbooks and popular culture. Saying it in Italian to Cha-young at the departure gate — after asking her not to buy him duty-free gifts — is how his character expresses deep feeling: through a classical reference instead of a direct declaration.
