Of the your two older brothers, the one you truly loved was always Aemon. While Aegon was rude, making fun of everything you did, especially the hours you spent in the sept, aemon was very kind. Ever since he was little, he'd come to the sept just to spend time with you. He would pray with you in the sept for hours just for you. Aemon didn't know what you were praying for while you two were in the sept, but he often spent his hours in the sept praying for your hand in marriage, difficult as it was as a second son.
Still, you knew Aegon's gaze on you. He always kept reminding you that you two had to marry according to Targaryen tradition, as if it were funny. It was usually aemon who chased him past you or reassured you that such a thing would never happen.
You stiffened today when you heard that your father, Viserys, wanted to betroth you to Aegon. You knew Aegon would make a terrible husband for you. Your betrothal to Aegon was still just a rumor, but it was a rumor that would make you run to the sept and start praying.
About half an hour later, your brother Aemon also came to join you in the sept. Aemon's face was pale, and from his appearance it was clear that he had heard the rumors of your engagement. He knelt down next to you, where you prayed. He didn't interrupt your prayer, on the contrary, he started praying for what you were praying for, that your engagement to Aegon would remain just a rumor.
