History Series / Stranger

* PowerWalk: Two Power Walks in episode 2-3, as the police (including Yeo-jin) and the prosecutors (including Shi-mok) both walk dramatically to the conference room where they are going to have their big meeting. (That meeting, in the next episode, is a confrontational fiasco.)

* TheReveal: Episode 2-15 reveals that in fact, Park Kwang-soo wasn't cleverly murdered; he actually did die of a heart attack. The only thing is, he died of a heart attack at a vacation house where he was partying with Woo Tae-ha and three {{High Class Call Girl}}s. In order to avoid a scandal and embarrassing questions all around, Woo Tae-ha and his friend Choi Bit from the police put Park's body in his car, drove it out to a lonely stretch of road, and left it there to make it seem as if Park died while driving.

* JailBait: Literally. Dong-jae claims that Moo-sung's MO was to deliberately match up his VIP clients with underage {{High Class Call Girl}}s, so he'd better be able to blackmail them later. Ga-young, it seems, was one of his underage hookers.

* LeftHanging: The storyline about the cop who may have been murdered by his bullying colleagues at Segok police station is never resolved. The last reference in episode 2-16 has Shi-mok sending his colleague Min-ha the file and urging her to continue the investigation.

That power struggle between the police and the prosecution is a main theme of the season. Yeo-jin's boss, Chief Choi, is determined to win the power struggle, so she deliberately publicizes the case of the drowning at the beach. The prosecution for its part is looking for material to embarrass the police, so senior prosecutor Woo Tae-ha recalls Shi-mok to Seoul and puts him to work looking for cases that could be used against the police. Shi-mok investigates the case of a police officer who officially was said to have committed suicide, but who in reality may have been murdered by his corrupt colleagues. Another mysterious case concerns a chief prosecutor, who was found dead in his car of a heart attack that possibly wasn't.

* RedemptionRejection: A dying Sang-joon, clutching Dong-jae's hand, gasps that it's not too late for Dong-jae to redeem himself. With literally his last words he begs Dong-jae not to follow the same path to corruption that he did. Dong-jae then goes to Shi-mok and pleads for a second chance, which Shi-mok gives him, hiring him back to the prosecutor's office. All that is undone in Dong-jae's last scene, where he's shown hiding in his office and making illicit phone calls to some crook, just like always.

* AssholeVictim: The two college kids who drowned at the beach in episode 2-1. Turns out it wasn't an accident; the third college kid, Hu-jeong, lured them there, got them drunk, and murdered them. It's also revealed that the two victims were horrible monstrous bullies who had been persecuting Hu-jeong since primary school and were ''still'' bullying and persecuting him, even after Hu-jeong had gone to university and thought he'd escaped them. Instead, they tracked him down and commenced ruining his life, taking over his apartment while stealing from him and selling off his possessions.

* ChekhovsGunman: Kim Hu-jeong, the third of the three drunken college students who went swimming in episode 2-1, the one that didn't drown. He's shown at the scene, then basically forgotten about, as in fact the drowning at the beach case is eventually dropped for other storylines. Then in episode 2-13 it's revealed that those other two college students weren't Hu-jeong's friends; they were his bullies and he killed them. Then he kidnapped Dong-jae after realizing that Dong-jae was putting the pieces together.

* BlandNameProduct: In episode 2-12 Tae-ha gets a text with a location from "Geegle" Maps.

* DistantFinale: The ending of the last episode skips forward ten months to find Shi-mok, who was dispatched to the coastal province of Namjae, being called back to Seoul to investigate the Prime Minister.

* MathematiciansAnswer: Shi-mok suffers one of his violent migraine attacks and has to leave a meeting in episode 2-12. After Yeo-jin hurries after him and guides him to a stairwell, she tells him that she told the others in the meeting that he had a case of diarrhea. Shi-mok is startled.

* LibationForTheDead: In the last episode Yeon-jae visits her husband Sang-joon's grave and pours out a bottle of soju.

** In episode 2-9, a policeman wonders why on earth the kidnapper posed a picture of Dong-jae's blood-soaked tie, musing that "Things like this only happen in American movies."

* ThisIsReality: In episode 1-2, the video tech tells Shi-mok that there's no EnhanceButton in RealLife, and the grainy image of someone opening the shades in Moo-sung's window is all they're going to get.
