* spoiler * WHO IS THE CURRENT SERIAL KILLER?

@Minarii I guess Head Hunter wants a father-son reunion in jail LOL. Remember when Han Seo Jun said to Sung Yo Han, "It's just that I'm curious how's my son been doing" I think he didn't refer that to Sung Yo Han as his son but more like a command or a statement.

 Max:

I don't think the Doctor is the Serial Killer, those pictures on his wall felt more like he was investigating the cases himself like a detective would. More than some kind of trophies.

When he was chasing the Granny, I don't think he had a murderous intent, he seemed more worried about her.

Maybe the reporter secretly got him some of those images.

I definitely think so too,  Also in one of the scenes, Yohan was talking to his mother about being the son of the headless hunter, and he had a very upset tone. I agree with what your saying, he might be chasing down people like his father, or solving it. And I don't think they would reveal the serial killer so easily.

I think JBR did kill in his past, but he's not the crosskiller. At least I don't think so, he's not a lefty either. Same as Jae hoon ;);)

Me too. The priest was my suspect number 2.

JBR is a psychopath he killed the bird and HH's ex-wife was afraid of him even she recalled the incident she almost killed her son when she saw JBR.  If you remember in episode 2 when JBR was on duty there was a cat that was cruelly killed and his colleagues said that the incidence of dead cats has recently decreased.  Maybe JBR had fulfilled his desire to kill by killing the cats in the neighborhood but now that he could hunt humans he didn't need the cats anymore.  But I still doubt whether he did it consciously or not.

I agree. So, my theory is that 60% sure from my gut. Ok, JBR is the son of HH, and Yohan knows that which is why he is investigating and following BR anywhere. BR is the killer from the get go. Maybe, he kills consciously and unconsciously or he has a dual personality. That I'm not sure. But, considering how smart and ahead of 3 steps the killer is, BR fits perfectly. YoHan has photos for investigating BR, that's why BR rush to his place. They had a confrontation and BR plays the weak, to fool everyone and clean his image. BR is both a genius and a psychopath. The bird from the beginning was just for us---the audience to look at BR as a good person. Now, HJ is pregnant and she'll have to investigate the truth behind Yohan's death. Y'all we have 10 more episodes left. It will be a hell of a ride. What I'm sure of is that the killer is not easy to play with.
