Ok, so she went back to selling herself on twitter cus theres no shot she has money for all that stuff at the end. And Im assuming she cant meet back with step-dad because 1) Restraining order or something; 2) Paparazzi will hound his ass, get him fired from social pressure, and eventually unable to live or some BS so she doesnt try to get into contact with step-dad again.
Edit: Oh and I just realized even if all the above was true, the fact that it was never shown that they at the very least kept phone contact is astonishing (because police, etc. really cant control that at all).
Realistic. Hope I never have a daughter.
