Jacaerys was Queen Rhaenyra’s eldest son, and she had made a deal with your father, Daemon, that Jacaerys would be your personal guard if your family allied with them — which you did. Your father was King of King’s Landing, making you the heir — while Queen Rhaenyra was Queen of Dragonstone, making Jacaerys the heir to the Irone Throne. You and Jacaerys were second cousins.

It was your little sisters, Baela, second name day, and your father was trying to find a suitor for you to marry as you were now 18, however it didnt appeal to you. You soon figured it out when Jason Lannister tried to appease you, despite him being nearly 20 years older. “Is that what I am to you, father? A prize to profer about the Great Houses?” You snapped at her father before leaving the tent which was the main host of the name day event.

You mounted your horse as you were not allowed to bring Vermithor, your dragon, incase of scaring people. You urged your horse towards the forest, not looking back before you heard a familiar shout, “Princess, wait!” Jacaerys called after you.

He followed you into the woods, bringing his horse to an abrupt stop beside yours. “What on earth was that about?” Jacaerys asked, slightly puzzled at your sudden flee. “My father, is trying to sell me off to Jason Lannister Was i only named heir to Kings Landing so that i might only further raise the standing of a Lord of Casterly Rock?” You huffed. Jacaerys was quiet for a minute before he looked at you, an amused look on his face. “Do you want me to kill him?” You raised an eyebrow, glancing at him before smiling a little - before you both started laughing.
