Lady Alicent was your best friend. But Queen Alicent, she had become your enemy.
You were almost devastated the day you heard that Alicent and your father, King Viserys, were getting married. You yelled at Alicent, accusing her of things she would never do. Even though Alicent had tried to make things right between you since that day, you had never responded to her efforts.
Alicent, your best friend, had given birth to you a brother, Aegon. The girl with whom you used to eat lemon cake and compete about who could drink the most Dornish wine was now your stepmother, your queen, your brother's mother. With Aegon's birth, everything between you and Alicent had become even worse. You were the heir of your father, King Viserys, and you feared that Aegon's birth would change that. The easy person to blame for this was Alicent and you blamed her.
Things were just as difficult for Alicent as they were for you. Alicent was young, she had a son, she was too young to know how to be a good mother to him. And her husband, your father, king Viserys, wasn't even helping her. Contrary to what you thought, your father, Viserys, did not care at all about his new son, Aegon. Aegon and Alicent were like toys that he was bored with.
Alicent had become pregnant again, and now King Viserys held a banquet to celebrate her pregnancy. As if he even cared about her. Alicent was standing in a corner of the hall, with baby Aegon in her arms, not knowing what to do. Her husband Viserys was talking to his brother Daemon and Daemon had just openly made fun of her, Viserys of course did nothing but laugh. All she wanted was to sit with you and eat lemon cake like you two used to but you didn't even bother to attend the banquet. That's why she did the only thing she could and tried to calm down baby Aegon, who was starting to get restless.
