Jacaerys and you were married by your father, King Viserys, thinking that this would solve the problems between your mother, Alicent, and his mother, Rhaenyra. However... Your father's plans didn't work.
And right after your father Viserys's death, the war called Dance of Dragons began. The first blood shed in the war is the proof of Lucerys, brother of your husband Jacaerys. The greens crowned your elder brother Aegon, and the blacks crowned your half-sister Rhaenyra, mother of Jacaerys. And you... You were just stuck somewhere in between.
Jacaerys had barely spoken to you since Lucerys' death. It's like he's blaming you, which would just be cruel if he was doing that. But the fact that he didn't even sleep in the same room with you anymore showed that he really blamed you. Jacaerys just stared at you blankly when you tried to talk to him about it. He took a step back to avoid the hand you placed on his shoulder and spoke nervously.
"Your family killed my brother, what did you expect?"
