Spoilers, as usual.

Have to say that so far I am not digging the whole OZ secret organization plot line, even though it was integrated into the show from the beginning. It’s sounding like the government is basically continuing Dr. Daniel Lee’s experiment, and trying to determine if Nature or Nurture is the cause of psychopathic murders. Of course they don’t see the irony in allowing and even encouraging test subject Ba Reum to kill people. This is likely at the end of the episode why Ba Reum declares to the government official that Dr. Lee asked him to kill her. From a certain perspective, what she is doing could be considered worse than being a psychokiller.

The biggest shock this episode was that Yo Han could have lived and OZ his supposed father insisted on using his brain for the surgery. Wow. The Headhunter is truly despicable.

Everything now makes sense as far as PD Choi and her baby. The baby is not the biological grandchild of the Headhunter, but since his wife raised Yo Han as her son, she considers his child to be her grandchild. PD Choi, we find out is the missing daughter of Detective Park, who was assigned to the case of the Headhunter. With her altered mental state, his wife recognizes the baby as her biological grandchild, which is why she kidnaps him. Interestingly, PD Choi has known this whole time that she was Detective Park’s daughter and was too afraid to approach him or her mom. Again, wow.

Now everyone is suspecting Ba Reum, and with good reason. Detective Go and Bong Yi both exhibit a lot of alternate denial and anger, which is totally understandable. It may be a good thing that Ba Reum is going to die in short order from his brain surgery, as I’m not sure how the three of them will or would deal with all of this. He’s a “good” guy now, but he still wants to murder people, just those considered bad. But that’s who he killed before, those people he considered bad. Not a moral improvement, though I admit he is saving some innocents.

Great scene with the Headhunter and his wife. He is creepily charismatic and she doesn’t seem like the kind of woman who would fall for that, but maybe she was much different when she was younger.

The murder of Detective Shin was the worst! He’s only a minor character, but the kid has grown on me. A chaebol, or son of a wealthy family, who has a good heart and a good work ethic. They had to kill him when he’s on his way to see his wife and their new baby…just awful. But it did give Detective Go a chance to freakout with his emotions. He’s going to need to do that a lot in dealing with Ba Reum, OZ, and the Headhunter.

Except for the OZ stuff, looking forward to episode 20. I am not sure if this is the last episode or not. We’ll see.
