A lot of weirdness with this show, but it’s all coming together. As Ba Reum sorts everything out about himself and Yo Han, the details are all getting filled in. However, I may be wrong in Yo Han’s motivation as a genius to stop killer Ba Reum: It appears there some shadowy organization called OZ behind all of this. An organization bafflingly covering up Ba Reum’s crimes, and also keeping tabs on him. Turns out they kept tabs on Yo Han. Dr. Daniel Lee, who is still inexplicably alive, appears to not be working with OZ, but maybe once was, and the suspicious detective I had my eye on is connected with OZ. OZ is either part of or just a nickname for the Ministry of Science and Technology. Possibly. We shall see.

The good thing is, that the other main characters like Detective Go (love that man!) and the ever spunky Bong Yi are now also coming to the realization that Yo Han may be innocent and that they haven’t got the killer after all. What both will do when they discover it is Ba Reum, I have no idea.

As for PD Choi, she has a new babysitter for her child, the wife of the Headhunter serial killer, and, if Yo Han is really her son, not Ba Reum, biological grandmother to said child. PD Choi herself is trying to show her former lover innocent, mostly so that people stop treating her kid so poorly, but I think also she feels it’s the right thing to do, to set the record straight.

We learn a bit more about Ba Reum’s past. AKA Jae Hoon, he may not be quite the out-of-control killer we all thought he was. That is, he’s not and has not just killed for no reason. At least one murder has been in revenge for the man who killed his mother. Turns out, too, that Ba Reum and Yo Han crossed paths as children and Ba Reum was impressed by the latter’s smarts and kindness, wanting to be like him.

Where is all of this going? For now, it appears the big twist is that Ba Reum and Yo Han were part of an experiment. True, we know they were part of Dr. Lee’s study, but this is something bigger, probably, quite probably a grand experiment thought out and orchestrated by a person who is real dad to one of them: The Headhunter, the neurosurgeon Han Seo Joon. I really hope that’s the case, because he’s got a creepy good presence and makes a great villain.

Hoping Go and Bong Yi take all the killers down, that Go marries PD Choi already, and that Bong Yi starts a completely new and better life elsewhere. Lab rats no more, let them live their lives in freedom! And Ba Reum, he’s got remorse and I do hope he finds redemption, though it will likely come with his death, as redemptions often are wont to do.

Still really liking the show, but there’s a lot of busyness that abounds, and I almost wish they’d do away with some of procedural stuff and get more to the heart of the matter: Are we dictated by our genes, or by what we do? Or both? It’s there, the question is there, just hovering in the background. Ba Reum now is governed by both things, though perhaps he wasn’t before his brain surgery. It has to be pretty awful to become self-aware and find out oneself is a psycho serial killer. The stuff of nightmares. But that is what sin really is, a nightmare, and it’s in all of us. And only by God’s grace can we overcome it.
