No one spoil it for me yet, but I think I know where they're going with the story of the kid with PTSD - I have a very strong suspicion that he's going the route of Joe from the one-off Punisher comic, "Do Not Fall in New York City." That issue is easily one of the saddest, most heartbreaking comics of all time, and if you're not familiar with it, then look it up. It was also adapted into an animated short by a fan.
