I love it when a plan comes together.
This episode starts grim, but gives us a big dramatic payoff. The team arrest Director Lee for ordering Han Byul’s murder, our central couple get some cute moments together, and finally—finally!—everyone takes a nap.
Well, everyone except Chief Moon, who never leaves the building and survives entirely on a diet of coffee and cynicism.
We start out with a big problem: special prosecutor Choi is supposed to get Chief Moon’s testimony. But Choi knows Moon has an alibi, because Choi was with Moon on the 19th and 20th of December. Choi turns off the recording devices in the interview room and has a frank talk with Moon. The result? The two senior prosecutors agree a battle with Director Lee would be ugly and hard to win. Instead, they’ll offer Director Lee something in exchange for letting Moon off the hook: they’ll close the Han Byul investigation.
Dong-Chi is furious when Choi suggests this compromise. He meets with Chief Moon himself to argue. The conversation reveals that Director Lee was behind a few of the coincidences that brought the Public Welfare team together. Lee knew Yeol-Moo was Han Byul’s sister and essentially appointed Moon chief so that he would muzzle her.
But, Chief Moon adds, Lee didn’t know about Kang-Soo. And why did Yeol-Moo come to this particular office? he wonders. Dong-Chi finally tells Moon something very important: that he was an eyewitness 15 years ago.
Meanwhile, Prosecutor Choi informs Yeol-Moo and Kang-Soo that they’re shutting down the case. He patiently listens to Yeol-Moo’s frustrated indictment of the system, and agrees that the system failed.
After he leaves, Prosecutor Lee comes in, agitated. He blames Yeol-Moo that he doesn’t have a job to go to tomorrow. Dong-Chi interrupts, looking defeated. No message has come from above, he says. The team is still officially disbanded. He delivers a line that Chief Moon said in an earlier episode: “You’ve all acted heroically. And let’s stop now.”
What a downer! Even Prosecutor Lee looks surprised and annoyed. Kang-Soo is furious. Yeol-Moo pulls at her hair in frustration, grabs her coat and leaves.
A few minutes later, Dong-Chi and Kang-Soo are leaving the building with grim faces. Chief Moon—now back to roaming the halls—wishes them goodnight and then, almost as an afterthought, he adds, “Did Prosecutor Han rush off somewhere?” The slight smile on his face suggests he knows the answer.
Director Lee brushes her off again and again, but as he grows more impatient he starts admitting to things. Yeol-Moo isn’t trying to be clever, but her blunt approach is perfect. Lee finally offhandedly admits to ordering the murder, mainly because he wants to prove his superiority to this annoying girl. As she curses at him, and he leaps up and grabs her arm, the office door opens. Dong-Chi, Kang-Soo and Special Prosecutor Choi enter. Dong-Chi tells Yeol-Moo to arrest Director Lee.
As everyone leaves the office, Yeol-Moo breaks down completely and sinks to the floor. Dong-Chi lifts her to her feet and holds her while she cries. After she betrayed him by giving up the sex tape evidence, and after he betrayed her by giving up Han Byul’s case, it’s a relief to see that they can still draw strength from each other.
At dawn they’re driving together and talking comfortably. She thanks him for following her to Director Lee’s office. He apologizes for letting her go into the lion’s den alone. And then Dong-Chi shares good news: the higher-ups finally came through. The team will remain together.
