What did it mean to settle a human into Sanctuary?
The answer to that question was a bit unclear. Such an act could have various consequences for example and that might be the answer one was looking for. But the answer could also be what would you need to provide the human.
On that note they'd need food, lodging, and also a sense of security. Human beings valued security. Once this feeling was lost, most human beings would abandon the place they were situated in.
The security could be something as simple as knowing that your boss at work will have your back. If the situation ever came that he didn't and you were somehow fired, chances were you wouldn't return.
The same sort of applied to the human girl in Sanctuary. If A was negligent and allowed the girl to feel threatened or insecure, she would never move past her prejudice that this was a city of monsters instead of a city of living creatures.
