That's the problem with the people around her. They prefer to speculate rather than just straight asking lol...you know, I think this is one time that even if she explained people would also approve her mindset all the same.
Making someone she already expects to be a genius (as long as she does not say why she thinks so) be taught in her land, and thus getting his loyalty. As long as she did her best in his education, and if she expects him to be brilliant she will.
