Cha-young is thrilling at the chaos they just caused on stage and compares the feeling to being in a 1960s mafia movie — a golden era in Korean pop-culture imagination for stylish American gangster films. Calling something '60년대 마피아' (1960s mafia) is a shorthand for cool, theatrical criminality rather than actual violence.
'성동격서' (聲東擊西) is a classic Chinese military saying meaning 'make noise in the east, strike in the west.' It describes the team's plan perfectly: cause a loud commotion over the union-busting scandal to draw everyone's attention away from the real target, the paper company funds. Gi-seok's enthusiastic explanation of it — complete with a physical demonstration — is a running gag about him always seizing teaching moments.
붕어빵 (bungeo-ppang) are fish-shaped pastries filled with sweet red-bean paste, sold from street carts especially in winter. They are one of Korea's most beloved cold-weather snacks and carry warm, nostalgic associations — which is exactly why Vincenzo brings them to a hospital visit. Gyeong-ja's joke is a classic dad-joke: the difference between a 붕어빵 (mouth shape: '붕') and an 잉어빵 (carp cake, mouth shape: '잉') is just the sound the fish's mouth makes.
Vincenzo calls the noisy bar a 'Korean-style club' — it is closer to a 포장마차 (pojangmacha) or a low-key 호프집 (hof pub) where groups book tables, sing, drink, and eat together rather than a Western nightclub. Singing along and banging on tables is completely normal; the atmosphere is communal and rowdy rather than sleek and distant.
Na Team Leader says he spent a month doing '차박' (cha-bak), literally 'sleeping in a car' — a hugely popular Korean leisure trend where people convert their SUV or van boot into a cozy sleeping space and camp at scenic spots. It became a cultural craze partly because paid campsites fill up fast and partly because Koreans love packing maximum comfort into small spaces.
'이이제이' (以夷制夷) is a four-character Chinese idiom meaning 'use barbarians to control barbarians' — in modern usage, let one enemy neutralise the other. Myeong-hui uses it to describe her plan to turn Babel's own people against each other. Like '성동격서' earlier in the episode, these classical four-character phrases (사자성어) pepper Korean conversation and Joon-woo's confession he doesn't know them is a small character detail.
The gallery's name 'Ragousing' (라구생) and its business model reflect a real phenomenon: high-value artworks are a well-known vehicle for money-laundering because prices are subjective and transactions are often private. Buying a painting for far more or far less than its real value can move large amounts of cash without leaving the kind of paper trail that bank transfers do.
The artwork 'Nothing' by fictional American artist Jackson Martin turns out to be a simple rubber foot mat — a classic satirical nod to conceptual and installation art, where the 'work' can be almost any everyday object given an elaborate intellectual frame. The curator's earnest explanation ('the emptiness of material civilisation perceived through the sixth sense') is a send-up of the kind of language used to justify absurdly priced contemporary art.
While the team nervously waits outside, the gold-prospector and the plaza residents kill time playing '잔 치기,' a Korean group drinking game where everyone taps their glasses together in rhythm and then drinks on cue. The simple chant ('tap glasses, tap glasses, drink, drink, drink, zzz-zzz-zzz') is almost universal at Korean group drinking tables and is designed to get everyone drinking at the same pace.
Vincenzo claims they are agents of the AISE (Agenzia Informazioni e Sicurezza Esterna), Italy's real foreign intelligence service, equivalent to MI6 or the CIA. Flashing a real agency name adds just enough plausibility to rattle the gallery director — and the show has fun with Vincenzo switching into fluent Italian ('Mamma mia!') to sell the cover.
Celebrating with a cold beer on a rooftop at night is a quintessential Seoul summer ritual. Cha-young's instinct to pair the beer with 족발 (braised pig's trotters) or 치킨 (Korean fried chicken) — the two classic late-night delivery foods — shows how deeply embedded this combination is. Settling for 육포 (dried beef jerky) if delivery feels like too much effort is the practical downgrade every Korean viewer instantly recognises.
