I think one of my favourite moments is in Pawn of Prophecy, where Garion and Polgara get into an argument about something. At the conclusion of which, after Polgara has naturally won, she concludes by saying "And Garion..." "What?!" "Don't even think about slamming that door."
You just know he does.
I've always envision that if that scene was played out of the screen. after the door slams. we would cut back to Pol who just has a wry grin on her face. Because she is seeing in Garion the kind of fire he will need to one day be king.
I think there is also a certain motherly love in the way that scene plays out. Garion in many ways is the child she could never have (though of course he is the latest in a long line) But since she at least suspects that he could be the one, she has a special attachment to him. She is always quietly prodding him in the direction he needs to go in order to be the man, father and king he will one day become.
But then the scene where she brings the ghosts of his parents back to see him always, and I mean always, makes me cry.
