I don't understand your post. AN was nineteen when she willingly walked into a Montana police station and requested to be taking off the "missing persons" list. That is legal adult age and, as I already mentioned, I do not think it's been established that ED held AN captive or confined her to the house, or prevented her from seeking dental care or anything else.
I could always be wrong, though. If you have information that ED held AN captive, confined her to the house or prevented her from seeking dental care or other care, please link to a source. I'm not trying to be argumentative, I just don't think there's any point in having a discussion with factual inaccuracies.
I also don't understand stating things as fact when they're not (at least, not to my knowledge) then adding "IMO" or the like afterwards. Does that mean it is really just your suspicion that ED may have done those things, even though you stated them as facts? If so, that might be where the misunderstanding/confusion lies. Thank you.
