But which master would hide their identity even from the kid's parents?
This, she could not understand. She could not accept it either.
But she would not voice out this opinion either.
She can understand where her son was coming from.
As a student, he can't go against his instructor's words or promise. But as a parent, she can't leave this matter alone either.
But she would not discourage her son by going against her son's words.
She can see that her son trusts his so-called instructor very much.
Though she doubts the identity of that instructor, she also trusts the eyes of her son.
He is not a person that would warm up to any person. Hence there should be something in the instructor that attracted him towards that person.
And the way he solved the questions earlier showed that the instructor was being a good influence on her son. At least for now. Hence she wouldn't jump into conclusions yet.
