It's not officially confirmed but probably the most popular theory about how Hambies are created is this: Remember how the Teacher made the virus based on fear? So to become a hambie, you have to be lacking fear and be determinated to something else to the point you don't care or even forget the danger you're putting yourself into. With Gwi Nam it was his determination to k*ll Cheongsan that made him lose fear. With the bullied Girl, she was determinated to get the phone, even while she was being bitten. And as for Namra, it was her determinaton to save Suhyeok, so she didn't care about the danger she was putting herself in. So essentially you have to have an emotion that overpowers your fear.
@@paulamuniz282 In that theory, yes he would be a hambie just like Namra, meaning he's alive. However because it's just a theory and not confirmed by the writers, we don't know for sure.
Rewatching this I realized something. It's mind blowing how the entire class was more or less fine with pink vest killing the guy just to prove herself right and the only reason she decided to leave was because she couldn't handle them calling her out. Why his friend (which has the personality of a piece of cardboard) was ok with that is super weird. If some chick killed my friend over a dumb reason like that her little ass would have got picked up and yeeted out the 2+ story window.
