– Inspector Koo episode 3 recap contains major spoilers –

Inspector Koo episode 3 starts with Kyung-yi questioning K about the death of the janitor in the hospital. The former mentions that a school student had gone to meet him just before he died and K acts shocked, mentioning that that’s highly suspicious. Kyung-yi continues questioning her and K continues to be confused and shocked, although the inspector looks unconvinced. However, she does mention that they are very similar.

Back in the present in Inspector Koo episode 3, Kyung-yi asks K why she is pretending to not know her since they met at school all that time ago. K acts all shocked and gleefully exclaims that she’s Mr. Jang’s wife, the lady cop. Her overreaction is a bit much and Kyung-yi gets a panic attack when K mentions to her about her husband and says that he’s probably in a better place.

Going back home with Santa, Kyung-yi hallucinates that her husband is there in the car with her. He gives him medicine to soothe her anxiety and tells her to try and work with others so that her anxiety doesn’t get so overwhelming. She asks him to stop and Santa looks back and sees that she has jumped off from the car. K, who was following Kyung-yi, sees this too and takes videos of her having a meltdown as Santa follows her.  

In the midst of a press conference, Yong Sook meets Je-hui and the latter tells her that she should go through her in order to talk to Kyung-yi. Yong Sook praises her, saying that she must be ambitious to put up a chain of command like that, and promises to go through her from now on. She also advises her to chase power and not money – that way, the money is sure to follow.

The team is later seen setting up an office space inside a storage unit. It’s a bit messy, but it’s better than nothing. The general is very happy, thanks to Kyung-yi, who is up to her usual antics. However, in between all this, Gyeong-su is confused regarding what exactly they are doing. Je-hui tells him, secretly (which was hilariously weird), that Team B is now a task force and they are going to catch a serial killer named K. Gyeong-su looks excited but depressed and says to himself that he knew that this day would come.

The four discuss why these people, who are not connected in any way, shape or form, were killed in the first place? How are they connected? Je-hui crosses off several options, and Gyeong-su says that maybe he has an office and accepts cases… like a PI but more murdery. Kyung-yi, however, is unconvinced.

Meanwhile, K’s aunt mentions how a med student who leaked a video of his girlfriend (presuming private content) got a light sentence – she says that it’s unfair since the victims are probably still suffering. One of them took their own life because of it. K looks really interested in him – setting him up to be her next target. She then hallucinates these really creepy things that I can’t even put into words and I am unsure how she just sits there seeing these things as if nothing is wrong.

The next day, K and Gun-wook hack into the WiFi of the café that the Park Gyu-il (the revenge porn guy) is sitting at and “copies” his phone to theirs because of which they start getting all of his text. I know it sounds confusing and is probably not as easily done, if at all. Anyway, K and Gun-wook are both disgusted at the congratulatory messages that he is getting.

K goes home and creates an unholy concoction. The scene between her and the delivery guy is mind-blowingly tense and will make you wonder whether K is ok (I mean, she isn’t, but you get it). We then see several people getting the message “it’s your turn”. We don’t know what’s going on yet, but I am getting it’s going to be epic. All of these people have the same keychain, so they are connected to K in some way.

The entire thing is a huge plan, one that takes up nearly the entirety of the second half of Inspector Koo episode 3. All that I have to say is that it’s elaborate and interesting to watch. It’s a little fantastical to think that K was able to pull this off and the number of people involved pushed it off without a hitch. But whatever, I can keep that in the back of my mind as I enjoy the clever absurdity of it all.

However, what’s more absurd is what happens after the Gyu-il dies – a woman, one of his victims, comes up to him and asks him to delete the video. However, when he doesn’t reply (because he’s dead) she stabs the bloody guts out of him. Poor thing is then taken into custody. K feels bad for her and the next day gives off a cryptic video that basically says that the girl who got arrested wasn’t the one who killed him.

Kyung-yi sees the video too, along with everyone else on the task force. They discuss whether K has done it, and Kyung-yi is pretty sure that it was him. Gun-wook is also extremely angry with her for putting them in danger and threatens her that he won’t keep her around if she keeps this up. K threatens back, saying that he isn’t helping her or anything.

Meanwhile, in Inspector Koo episode 3, Kyung-yi is at the morgue checking out the dead body and realises that a small girl couldn’t have simply stabbed him without Gyu-il having some defensive wounds. She also finds the camera cap and is able to deduce with the help Gyeong-su that there were different compounds used to kill Gyu-il.

The team is able to find the guy who brought the balloons and through some clever manipulation on Kyung-yi’s part, she gets a hold of his devilish keychain. Kyung-yi follows him around and catches him selling his camera to a woman who also has the devil keychain. However, she goes one step over Kyung-yi and leaves her on the train. However, she does send pictures of Kyung-yi and Santa to K.

That night, in Inspector Koo episode 3, Kyung-yi becomes a “lawyer” to talk to the girl who stabbed a dead Gyu-il. The two talk about her guilt and Kyung-yi assures her that she did not kill him. However, she did stab him and she will have to live with that for the rest of her life. She also asks her to call her if anyone calls her to help her in the future. The girl asks Kyung-yi whether the person who helped her is good or bad since they only kill people who deserve it. Kyung-yi doesn’t answer.

In a flashback, in Inspector Koo episode 3, Kyung-yi is seen giving K tips on how to be the perfect murderer. It’s an absolutely appropriate discussion, one a police officer should not have with a student, but here we are. K, thus, is following every suggestion that Kyung-yi had given her all those years ago and is thus so difficult to catch.

In the last scene in Inspector Koo episode 3, Santa is seen in a vacant parking lot being followed by a disguised K. As the ending hangs on a thread, we are left with the dread of Santa being possibly hurt in the next episode.

Final Thoughts: Inspector Koo episode 3

Inspector Koo has been an intriguing series from the first episode and episode 3 is nothing short of extremely interesting. Every moment you wait with bated breath as to what is going to happen next and that is only possible because of the horrifying antagonist. The protagonist and the supporting characters are great too and episode 3 had some funny moments and moments of emotion. However, the moments where K is plotting her next move are the most interesting, and so are the executions. So, does Santa get hurt? I really hope not!

Inspector Koo is streaming on Netflix.
