Jaime was your uncle, you were born to the Lannister family with Cersei as your mother but you were the only true Baratheon.
Nothing was ever really the same after your father, King Robert, had died. With Joffery on the throne and your mother constantly whispering in his ear, you found Solace in confiding with your other siblings. That was until Myrcella was sent to Dorn and Tommen grew distant. Tyrion had yet to come back to Kings landing and Jaime was still a prisoner of the Starks.
It had been weeks since you had any sort of meaningful interaction, except maybe talking to your mother about potential suitors but that didn't interest you.
It was late and most of the Red Keep was silent, it was an almost eerie contrast to how busy and loud the days were around the castle. You sat in your room, surrounded by candlelight as you brushed your hair in front of a mirror. Everything was quiet until there was a knock at the door. The door opened before you could even get up, it was Jaime.
