What's wrong with Alicia?

Would he really sell her if he felt that she wasn't needed anymore?

The only that was in her mind was that question, even when she was sitting in her classroom, waiting for the bell to ring. There was nothing else. She didn't mind the witch with red-hair that didn't match the description of the rest of the city, which meant she was an outsider. She didn't mind Alicia that had her eyes on her the whole time as if she wanted something from her.

If she was sold again, could it be she would be killed quickly?
