So all the scars were easily cured, ad her "family" were not concerned with the possibility of someone finding out she had easily removable burn scars?
@sjmcc13
They probably didn't expect for her to meet anyone since normally she just stays home.
It's also possible that they didn't want to hire someone to heal the burns since they might ask questions.
@sjmcc13 you will find that a lot "evil people"(for lack of a better word) in real life are incredibly brazen and lazy when deciding a course of action.
It is a combination of a lack of empathy and a massive ego. If you truly believe you are not doing anything wrong then why would you put in the extra effort?
