Well, if they're referring to the Numbers, they'll always use numeric ("001"), whereas this new One guy will be spelled out (even in the raw).So many "one" that I was confused which one is the "number" or "name".
Might be better if there's a quotation mark if it's referring to name.
From what I understand, if even Mad Dog is afraid of him, we can say that he's something far worse than Mad Dog. But I imagine he has the mentality of the "Camp," so he protects those who were part of it. That's why 003 and 005 were preserved; otherwise, IJin and the rest of the "Numbers" would have already gone after "One."For the first look. I think he is 002. Cause they're look alike. And the plot he's 002's brothers. Idk he will be their enemy or friend .
