Rhaenyra had already lost her sons Lucerys, Jacaerys, and Viserys. Even though She had now taken the Iron Throne, but only you, Joffrey and Aegon were left to her. Her three children were a price the queen was unwilling to pay for the iron throne.
Now, you and Rhaenyra were arguing. The people were hungry and that's why they started to hate your mother. Rhaenyra didn't care if the people hated her. But you wanted to go to the people and talk to them, at least shake the hands of the old people, hug the children, and distribute some of the palace's food supply, hoping that the people would love your mother Rhaenyra again.
But your mother was strongly against this idea. The queen, whose paranoia was increasing, was absolutely against you going out in public. Rhaenyra looked at you, a hint of resentment appearing on her face. She raised her eyebrows as she looked at you. She would let people starve to death if her children would be safe. She spoke slowly.
"Do you think I'm cruel?"
The Queen vaguely shook her head no. She sighed. She was too worried about you and wouldn't let her only daughter do something dangerous like that. She fixed her gaze on the wall and spoke.
"I am a mother."
