A 재정 증인 (jaejŏng jeungin) is a witness the court itself summons, separate from witnesses either side calls. Vincenzo is exploiting this mechanism because the defence cannot simply reject a court-ordered witness the way they could reject a plaintiff's witness — making him almost impossible to block.
Vincenzo walks up to the Babel employees at their restaurant table and announces they are going to 'get hit.' In Korean crime and action dramas, a villain personally delivering this kind of calm, face-to-face warning before violence is a deliberate power move — showing total confidence and contempt. The restaurant setting (사람들이 밥 먹는 자리) makes the intrusion even more insulting.
필로폰 (pillop'on) is the common Korean word for methamphetamine, borrowed from the Japanese brand name Philopon used during the colonial era. It remains the standard term in Korean news and legal proceedings. Dr. Gil's wife presents what she says is his personal supply, destroying his credibility as a witness in open court.
Korean courtrooms follow strict decorum rules, and outbursts are rare and scandalous. Dr. Gil's wife launching a physical attack on her husband inside the courtroom — and calling him 거지새끼 (a penniless wretch) — is an extreme breach of 체면 (ch'emyŏn), the social face every Korean is expected to maintain, especially in a formal public setting. The scene is played for dark comedy precisely because it is so far outside acceptable behaviour.
Joon-woo mentions bribing prosecutors and politicians in the 남동부지검 (Namdongbu District Prosecutors' Office). In South Korea, the relationship between large conglomerates (재벌, chaebol) and the prosecution has long been a subject of public distrust and reform debate. The show uses this as realistic texture — Babel essentially has prosecutors on retainer.
Cha-young is buying Vincenzo bespoke suits as his 'incentive.' High-end 맞춤 양복 (custom-tailored suits) from boutique ateliers in neighbourhoods like Cheongdam or Apgujeong are a significant status symbol in Korea. The tailor measuring Vincenzo and marvelling at his proportions is a nod to Italian tailoring culture colliding with Korean luxury fashion.
차박 (chabak) — sleeping in your car as a camping style — exploded in popularity in Korea around 2020–2021 as a socially-distanced outdoor trend. 감바스 (gambas al ajillo, Spanish garlic shrimp) became a trendy campfire dish at the same time, turning up everywhere on Korean food and lifestyle social media. The team leader name-dropping both signals he is trying hard to seem like a wholesome, on-trend family man.
손흥민 (Son Heung-min), the Tottenham Hotspur and South Korea captain, is the most celebrated Korean footballer ever and a genuine national hero. Saying a youth scout is looking for 'the next Son Heung-min' is the highest possible compliment in Korean football — roughly like saying a baseball scout is searching for the next Ryu Hyun-jin. The show will use this reference to set up Vincenzo's plan.
서초동 (Seocho-dong) in southern Seoul is home to the Supreme Court, the Seoul High Court, and the Seoul Central District Court, as well as thousands of law firms. It functions as shorthand for the entire Korean legal establishment. Cha-young's remark that rumours in Seocho-dong travel instantly and mercilessly reflects the real gossip culture of this tight-knit professional community.
The five-colour USB drives the detective holds up prompt Cha-young to joke that each colour represents an Olympic Games — meaning if she serves all five charges, she will be inside for three Olympic cycles (roughly 12 years). The 오륜기 (oryungi) is the five-ring Olympic flag. It is a darkly comic piece of improvised Korean math-humour, and she uses it to stay cheerful while being walked out of the police station.
BC밀라노 and its director Giuseppe Rossi are fictional stand-ins for AC Milan. Korean dramas cannot use real club names without expensive licensing, so near-identical fictional versions are common. The scene works because Son Heung-min's real-world success has made European youth scouting a genuine dream for Korean football families — Vincenzo is exploiting a very real parental aspiration.
기석 uses the gamer slang 템발 (tem-bal), short for 템 발굴 — 'digging up items' or 'scoring gear,' drawn from RPG games where players find equipment. He is calling the protest banners, hard hats, and red jackets they borrowed from a neighbouring demonstration their 'loot.' This kind of gaming vocabulary slipping into everyday Korean speech is very common among younger Koreans.
미쓰 양stops the gangsters mid-raid to collect their meal receipts for 부가세 신고 (bugase shingo) — VAT tax filing. In Korea, small business owners must file VAT returns quarterly, and the deadline is a genuine source of stress. The joke is that the mob enforcer is just as subject to mundane Korean tax bureaucracy as anyone else, and cannot even launch an attack without sorting out his receipts first.
