국두 yells '이 새끼야!' — 새끼 (saekki) literally means 'offspring of an animal' and is one of the harshest all-purpose insults in Korean, roughly equivalent to 'you little bastard' or a stronger expletive. Hearing a detective shout it signals the scene has crossed into raw, unscripted fury rather than professional conduct.
The show treats Bong-soon's super-strength as a hereditary gift that runs exclusively through the women of her family line (혈통, hyeoltong — bloodline). The father explains that because the daughters absorb all the family's strength, the sons have historically been sickly, which is why the mother fussed over Bong-gi so much. This logic echoes Korean folk beliefs that certain gifts or fates can be 'carried' in a family's blood.
Bong-soon says she'd been secretly squirreling away part of her salary to buy her friend a dress. The verb she uses, 꼬불치다 (kkobulchida), is vivid colloquial Korean for hiding money from a joint pot — the image is of folding or curling cash away so no one sees it. It's the kind of word a Korean listener immediately recognises as warm and slightly mischievous.
Do-dol-ppyeo shouts 'Run! Do Bong-soon, Run!' in the rhythm of the famous line from the 1994 Hollywood film Forrest Gump. K-drama villains and comic sidekicks frequently drop English-language movie quotes as a way of being theatrical, and the joke lands here because a powerless Bong-soon is struggling to carry paper boxes that she would normally flip with one hand.
The monk raves about the bathhouse's 소고기 미역국 (sogogi miyeokguk — beef seaweed soup) while quickly clarifying he does not eat meat. Miyeok-guk is one of Korea's most iconic soups: seaweed simmered in a savoury broth, traditionally eaten on birthdays and after giving birth because seaweed is associated with recovery and nourishment. It's a running gag that even a vegetarian monk can't resist talking about it.
The on-screen text reads '역량기' (yeongnyanggi), a personal record book Bong-soon has kept of her powers. 역량 means capability or capacity, and 기 can mean a record or chronicle. Seeing the notebook now — just as her strength is gone — underlines how completely her identity has been tied to abilities she has had since childhood.
Jang-hyun tells Bong-soon she promised to marry him, and frames the bomb threat as punishment for breaking that 'promise.' Korean thrillers often use twisted domestic language — marriage, family, loyalty — as a way to make a villain's possessiveness feel even more unsettling, because those concepts carry heavy cultural weight around duty and keeping one's word (약속, yaksok).
With the bomb ticking, Bong-soon prays desperately for her strength to return so she can save Min-hyuk. The prayer is not addressed to a specific deity — it is the kind of instinctive, non-denominational plea that appears throughout Korean dramas regardless of a character's religion, reflecting a broad cultural habit of crying out to 하늘 (haneul — the heavens) when all other options are gone.
