채신 and 적하 are chanting '관세음보살' (Gwanse-eum-bosal), the Korean name for Guanyin, the Bodhisattva of Compassion. Repeating this name is a core Buddhist devotional practice — like a mantra — meant to invoke her mercy. The protesters have brought monks into their demonstration to amplify the moral weight of their cause.
Judge Heo is speaking in a thick Jeolla-do (전라도) dialect, dropping standard endings and swallowing syllables — '잃어 뿠어' instead of '잃어버렸어,' for example. Regional dialects carry strong associations in Korean dramas: Jeolla speech often marks a character as blunt, earthy, or from outside the Seoul elite, even when that character holds institutional power.
The judge tells the lawyer to repay favors '물밑으로' — literally 'underwater,' meaning covertly, beneath the surface. It's a common Korean idiom for back-channel dealings. The joke is that the judge spells out the bribery arrangement cheerfully in a restaurant hallway, right before walking into the courtroom.
홍유찬 was acting as a 국선 변호인 (gukseon byeonhoin), a court-appointed public defender, for the imprisoned woman Gyeong-ja. Unlike in some countries, Korean public defenders are often overworked and underpaid; a lawyer who visited every single month without fail — as Yuchan did — would be seen as going far beyond the call of duty.
번뇌 (beonnoe) is the Korean rendering of the Sanskrit 'klesha' — the mental afflictions, anxieties, and worldly attachments that prevent spiritual peace. The monk's reply reframes it: rather than something to be escaped by going somewhere remote, 번뇌 is something you must fight from within. It's a classic Seon (Korean Zen) teaching, and the monk delivers it gently but firmly.
스투키 (Sansevieria cylindrica, a type of snake plant) is enormously popular in Korean homes and offices because it thrives on neglect — going a month without water is no problem. Vincenzo points out that this drought tolerance makes it the ideal hiding place for electronic bugs, since watering the plant would destroy the device. It's a real tradecraft concern: intelligence agencies worldwide have planted bugs in office greenery.
The reveal that 장준우 is the eldest son of a first wife (본처) while 장한서 is the son of a much younger secretary (비서) echoes a real pattern in Korean conglomerate (재벌) history. Succession battles involving children from multiple relationships — sometimes kept secret for decades — have played out publicly in families like the Samsung and Lotte founding lines, making this storyline feel immediately believable to Korean viewers.
히로뽕 (hiropong) is the most common Korean colloquial term for methamphetamine, borrowed from the Japanese brand name Philopon used during the colonial era. In Korean legal and news contexts it appears constantly; being found with even a trace amount triggers automatic criminal investigation. Planting it on a witness is a classic frame-up move, and Korean viewers would instantly understand the severity of what Babel has just done to 이우영.
