Well, well...
A comment from me that should have been made a long time ago. As we talked before, this is a story without heroes. All the characters are "purely" human. With flaws, desires, hopes and dreams. Each of them has something that makes you hate and love them (except my "hated" one (you know who he is).
Despite the fact I see a Nick that is too broken. He was used and abused. Taken for granted beyond repair. Until he had to snap... In the most violent way.
Then we have Bobby. A kid hunger for affection, that took the scraps that a psudo-father gave him.
Two broken and abused persons that found on each other the strength to carry on.
