Damn, the dude is cold. He thinks she doesn't even need a name, just her job title is enough.
@BananowyJE The series would be very different if the dude was more mature. If he was older, yet it was still like this, we, as readers, would find it implausible and annoying. If he was an adult man, he would already, realistically, not want anything to do with a killer, being too afraid of the consequences (you are assisting a criminal by hiding them from the law enforcement). If he still did end up accepting her, for some reason, the balance would be different because an older person, with more life experience and common sense, would act more like a guardian compared to Shue who knows nothing of life, only knowing death. So, from this point of view the dude needs to be that young to have this kind of atmosphere and relationship between those two.
In fact I think no 16 years old would anymore run in front of a truck, but I guess the author didn't want to bother too much with the scene of Shue saving his life.
