Ma Ri PISSES ME OFF!!! So it had Yoo Jins sisters DNA on it, that makes her guilty, please enlighten me with your logic- he had her bloody face on his wall, yeah sounds so guilty, now she wants to know if she displayed anyway psychopathic qualities ahhhhh the unlogicalness stuff is killing me. Yes I realise that the ending might support her theory, but to her it should be far more likely it was dna from her dead body, and how callous she treats Yoo Jin, does she have no sympathy, in any way??
I feel that the Subway killer is targeting people surrounding Yoo Ryung's sister- after she'd been abandoned... there was a brief clip of her when the police officer remembered arresting him. Dunno?? Anyway, so glad that the next ep is going to resolve the angst!
