That honestly bothered me too, but i think it was because the girl who bit her was still human and wasn’t turned…
well the school nurse got bit right after On Jo and she turned so it wouldnt have mattered if she was in the process or not. I honestly think they just forgot about it. Because when the friend came back from the nurses office she said that On Jo got bit and had to get treated but she never turned at all. So either they forgot about it or she is immune to it like someone else mentioned.
I don't get why everyone keeps thinking that the profiler Eugene is one of the main guys sibling? I swear in one of the episodes, the dad told the Doctor that he was going to be a big brother to a little brother. That his mom was pregnant with a little boy not a girl?! Or did they translate that wrong? I'm really confused on that part.
That's why I think that the two male leads are siblings.
What I'm thinking is that the main lead had an older sister that died in the fire but the mom was saved. She got pregnant again or she was pregnant with the male lead but felt guilt for losing her daughter and tried to commit sucide and then the cop found her and saved her and took care of her. That's what I'm thinking. I dont think any of the characters are related blood. Instead they are connected through the incident that happened back in 1984. i.e. the doctors' dad got blamed for being chimera, the police guy's connection to 1984 with the old man and I'm still figuring out why the female lead is connected. Anyways, that's my two cents. Lol!
