Well, the shot looked to be in the intestines area and kinda centered, not a fatal shot in most cases, the problem is the bullet could hit her spine and she would become paraplegic and she could get a pretty bad infection, but considering their money I'd say the odds of Julia dying are kinda low from a realistic POV, of course MrJet could kill her because it's how he wants to progress the story, but I wouldn't worry too much, I agree with most people that think this is going to be used to put the CPs in action as they are pretty much useless for now.
