Why do you think in the books there are mentions of Harry looking scared of Harry? Does Harry believe she is scared?

I don’t think she is truly afraid of Harry but some quotes do stand out to me like when she steps back after he roars in frustration when they are arguing about whether his vision was true or false. She still refuses to back down but in this book you do see mentions of her looking nervous and carefully choosing her words. In book 7 at one time, it says she seems worried he would curse her with his own wand.

I don’t think she fears him but there are some passages which do seem to some apprehension. I think most of the time she is worried about him, his emotional wellbeing and she worries he will do something really reckless. However it is isn’t pleasant for her when he is mad at her and when angry he can be intense. Yet she is never a pushover
