So clearly the real killer is some dude with a fatal disease... Someone aware of Do Hyun's father's methods of killing... Either was an accomplice or was able to find out somehow...
Perhaps related to Moo Jin? It seems like he may have some connection to the original serial murders. Maybe he even has some recordings of it?
I don't think Do Hyun killed the village foreman either. He seems to have some trauma that prevents him from actually killing people.
This leads me to believe two possible scenerios:1. That there are two killers. The killer in World A knows their…
Maybe the two killers are aware of each other... World A version has been helping World B commit the killings (hence, there never being evidence of himself committing murders).
Meanwhile, World A version (who also does the world crossing) commits killings he cannot technically be tried for since he's not a resident of world B where he is committing the killings.
Both get there murder fixes satisfied. (Maybe they even take turns)
Eps 7 and 8 are amazing. I'm not ready to lose Do Won B. I believe in the end he will die, but this quickly. I'm…
In the end both Do Won's have very different destinies...
World B Do Won was always destined to save his father and it repeats itself again this round... World A Do Won was always destined to arrive too late and witness his father's death and in this case, it repeats itself again with World B's version of himself and his father...
I have a new theory after watching the preview of episode 9:
There are two killers, both are versions of the Psychiatrist.
One, from World B, doesn't know about the two worlds (or at least that is as far as I can tell since he's surprised to see Do Won alive).
The other, is actually from World A but has been crossing over to kill people in World B and tossing their bodies in World A (this way, he's always free from being implicated).
Of course, there is a flaw in this theory:
Sung Wook has clearly been helping kidnapping victims and it seems the killer is also World B Psychiatrist.

My second theory is that the World A version of the psychiatrist was in the car accident that disabled World A version of Sung Wook and has been either dead or comatose ever since.
World B Psychiatrist is only surprised to see Do Won still alive since he didn't imagine that World B Do Won having traveled back to this world.

Now I'm kinda worried for World B Seo Kyung...
Kinda feels like the big villain reveal has happened too quickly

What I'm really curious about is Baek Hee Sung's parents. Who are they? Why are they covering for Hyun Soo? Where is the real Hee Sung?
