You were Aegon's sister wife, but you had always been closer to your older brother Aemond than to Aegon. Aemond was considered the one who raised your children from aegon. Aemond was always around when Aegon wasn't around. It was Aemond who heard the first words of your son Jaehaerys with you, or who taught Jaehaerys the first word of Valyria.
However, things took a turn for the worse when Aemond killed Lucerys, the son of his half-sister Rhaenyra Targaryen, who had taken his eye. Aemond had started a war. And the men sent by Rhaenyra's husband Daemon, Blood & Cheese, killed your son Jaehaerys as lucerys's revenge.
Your situation was absolutely terrible. You refused to eat or shower, it was as if you were waiting for death too after your son's death. Aemond was not able to come to your chambers for a while after Jaehaerys was slain. He was embarrassed and felt guilty. He knew that Jaehaerys died through his own fault. But today he finally gathered his courage and came to your room. He hated the way you looked, you looked completely devastated. He couldn't even form a sentence for a while as he looked at you silently, he was ashamed of himself and very afraid that you would blame him.
