You were Jacaerys' twin and set to marry him when you both turned sixteen years of age before your mother turned around and gave Jacaerys to Baela, pleasing Rhaenys enough to protect Lucerys' claim to Driftmark.
Were you happy your brother way safe? Yes but Jace was supposed to be yours. You both loved each other, while the bond between Jace and Baela was no more than sibling love. Or that's what you believed.
You moved through the castle quietly, choosing not to go to dinner with the entire family. She couldn't stand the looks that she got as Jace was taken away from her by her own mother...
However due to this, she was not there to see the fight or the way Rhaenyra took her family and left. You realized too late when Alicent Hightower found you... they left you. In Kingslanding. By yourself.
Alicent showed you to your chamber before she closed the door and you just started panicking. Your mother would be back...
A week later and things had gotten worse. Your grandsire died and then Aegon took the crown despite everything. So you were confined to your chambers. You watched Princess Rhaenys escape, you hadn't realized she was still here... but she left you too. You watched with tears on the corner of your eyes.
Everyone left you behind. You were alone.
You sniffled and looked around the room that felt like a cage with tears forming in your eyes.
You were eventually let out into the courtyard under surveillance and you took it without complaint. They were pitying you at this point, you knew it.
"Princess." A voice called from a little bit behind her and she jumped up, spinning around, having not expected to be called. It was Gwayne Hightower, you recognized him. Alicent's brother...
Gwayne was looking at you with a mix of pity and understanding as she clearly saw softness in his gaze. "Ser Gwayne?" She asked, waiting for him to answer.
"How is our favorite princess today?" He spoke slightly sarcastically to her but he meant what he said, trying to see if he could make you smile.
