Honestly, I am glad that she's actually trying to help her brother. She wants to give him the love and affection that he yearns for in his heart. I like how he's able to recall a vague memory of their childhood. Sometimes, the fear, anger, and hatred over what's happening in your life can blur out the happy memories of life.
If she keeps going this way, she can definitely change him for the better and be able to help him become a kind emperor.
