Still not sure what Dr. Lee's role is in all this? Is he also not crazy, because he wants to prove to the world at all costs that unborn children with a psychopathic gene should be removed before they will born, because in the future they do more harm than good? He did not release Ba Reum to the police, because, as he claims, he did not have much life left, because he was going to die inevitably, which also happened to the mice after a failed experiment. It all seems terribly confusing. And that Dr. Lee's assistant had taken the evidence of the crime from the Ba Reum house; Father Koo's chain and Oh Bong Yi grandma's brooch!? How did he even know where to look for them? Or maybe they put them there themselves? It all seems suspicious!
