The team decides to call Babel's hidden boss '바보' (babo), which literally means 'idiot' or 'fool' in Korean. It's a cheeky double meaning: it works as a shortened codename for 'Babel's boss,' but it's also a quiet dig at whoever is pulling the strings behind the scenes. Korean audiences would catch the joke instantly.
Cha-young mentions she never ate 미역국 (miyeokguk, seaweed soup) before important exams. In Korea, eating the soup on exam day is considered bad luck because seaweed is slippery and students fear their knowledge will 'slide away' — just as seaweed slides in a bowl. Students take this seriously enough to switch to plain rice or toast the morning of a big test.
Cha-young compares the mapo tofu she's eating to a tomato pasta from 'Vincenzo Cassano's hometown.' Vincenzo's character is from Calabria in southern Italy, a region known for its bold, tomato-heavy sauces. The comparison is a playful cross-cultural compliment — Korean mapo tofu and southern Italian pasta share that deep, slow-cooked red richness.
The district chief prosecutor jokes that Jang Han-seo looks young enough to be his nephew, so he'll accept the poured drink with just one hand. In Korean drinking culture, receiving a drink with both hands — or at least one hand touching the forearm of the receiving arm — is a sign of respect toward an elder. Accepting with a single, casual hand signals that the senior person is comfortable enough to drop formality.
Cha-young asks the victim's family to bring back a bottle of 구기자 술 (gugija-sul) from their trip to Jindo. Jindo, an island off Korea's southwest tip, is famous for its wild goji berries, and the local liquor made from them is considered a genuine regional specialty — the kind of thing you can only really get from someone making the trip. Asking a virtual stranger to bring you a bottle is a sign of warm, comfortable familiarity.
Cha-young declares she is a 유단자 (yudanja) — someone who holds a black belt or higher dan rank — in three separate martial arts. Taekwondo, judo, and hapkido all use the dan ranking system, and listing combined dans is a Korean way of flexing credentials in an argument. She totals them as seven, then corrects herself comedically, which undercuts the bravado perfectly.
Vincenzo pokes fun at Cha-young's elaborate pyjamas by starting to cite their brand origin — '브랄로 창사 80주년 기념,' meaning a commemorative item for the brand's 80th anniversary. Mentioning a brand's anniversary edition is a common K-drama shorthand for something absurdly expensive and niche. Cha-young cuts him off before he can finish, which only makes it funnier.
When the crew is broke and hungry, Seok-do tells someone to put water on and says he'll go buy 짜파게티 — Nongshim's popular instant jjajangmyeon noodle. It's the Korean budget comfort food of choice: cheap, filling, and associated with getting by on very little. The detail tells you everything about how far the Antt Company gang has fallen.
Hong-sik proposes they search for the gold using '학익진' (hagikjin), a historic crane-wing military formation famously used by Admiral Yi Sun-sin in the 1592 Battle of Hansando to encircle and trap the Japanese fleet. Dropping a 16th-century naval tactic into a treasure-hunt squabble is vintage Korean historical-drama vocabulary used for comic effect — every Korean school student learns about this battle.
The restaurant serves 고구마 맛탕 (goguma mattang) — chunks of sweet potato deep-fried and coated in hardened sugar syrup — as an amuse-bouche. It's a beloved Korean street snack and side dish, so getting it as a formal 전채 (jeonchae, starter) in a sit-down restaurant is unexpectedly homey and a little absurd. The callback to the earlier episode joke about eating sweet potatoes at the wrong moment adds another layer of comedy.
