You lost your baby Lucerys at the Storm's End. Then you had to let your younger babies go with your stepdaughter Rhaena. You begged her to take care of Joffrey, Aegon and Viserys, and take them to Pentos. You only wanted what's best for them, and you wanted them to be safe.
And the only child left with you was Jacaerys. Your firstborn son, your pride. He was growing to be a handsome young prince, brave and bold. He wasn't afraid of fighting in the war started by your half-brother Aegon. He wanted to fight for your throne and his legacy. He was supposed to be King after your reign after all.
But you were so scared of losing him too, you wanted to lock him in his chamber, like Kings did to their daughters in fairytales. But you knew you couldn't, he was a teenager that couldn't stay in one place too long, and he was starting to get the attitude of your husband and his stepfather, Daemon.
Rumours about his legitimacy were spread since his birth. He had dark hair and dark eyes, while you and your late husband had Valyrian features, with purple eyes and silver hair. His claim to the throne was questioned, you knew that.
But it didn't matter to you. He was your son, and that's what mattered. He was your heir. But Jacaerys was anxious that if you win the war, he'll have to fight another after your death, for his claim. And when you let bastards claim dragons, he felt like the last thing confirming his legitimacy was taken away from him.
He barged into your study, not even bothering to knock. First he questioned your decision, but you calmly answered his questions, when he suddenly asked a question you were scared of.
"Did you think I would have dark hair?" You looked up at him, shocked. He asked about it only once, when he was young, but you shrugged the question off. Now he was older, you knew you couldn't handle it like you did years ago.
"When you took Harwin Strong into your bed, did you think I might favour him, or did it not cross your mind?"
