You know what I'd like to see? A preview to Robert's Rebellion, about the reign of Aegon the Unlikely and the Tragedy of Summerhall and in this I would love to see how Aerys II changes. I want to see Aerys start out as this somewhat charming, generous, ambitious, if quick to anger, quick to love, and quick to lose interest man, and end as the absolute fire-obsessed, abusive, sadistic monster he became.
I want to see the inseparable childhood friendship between Aerys, Tywin Lannister, and Steffon Baratheon. I want to see Aerys fighting in the War of the Ninepenny Kings and in the Stepstones. I want to see Aerys's reaction to the Tragedy of Summerhall. I want to see Aerys's early reign as king, starting with him making arguably good choices as an active ruler, and the prosperity that came from his and Twyin's actions. Aerys and his friends had the idea that Aerys would be a good king and become known as "Aerys the Wise" or "Aerys the Great," and I want to see that happy, energetic optimism.
I want to see the "inseparable" friendship between Aerys, Tywin, and Steffon devolve as Steffon leaves for the Stormlands and starts his own family. I want to see Aerys and Tywin's friendship sour after Aerys's behavior at Tywin and Joanna's wedding and disputes between King and Hand. I want to see Aerys want to hang Tywin and name Steffon as Hand, and then see how he reacts to Steffon's death at sea. I want to see Aerys choose Jaime to be a member of the Kingsguard and how this impacts Aerys' and Tywin's relationship. I want to see the Aerys Jamie knew. I want to see how poorly the Defiance of Duskendale is handled, and Aerys' choices become increasingly worse as he descends deeper and deeper into madness. I want to see how Varys comes into the fold, and what his and Aerys' relationship started out as, and how it changed. I want to see Aerys's appearance transform from a handsome youth to a repulsive, corpse-like figure with matted hair, claw-like fingernails, whose mood swings worsen over time.
I want to see Aerys and Rhaella's relationship devolve. I want to see the relationship go from "we are siblings and don't really like each other" to "we were forcibly married by our father and are trying to make the best of it." I want to see the pregnancies, miscarriages, and stillbirths, and I want to see how Aerys turns from being "compassionate" and "comforting Rhaella" about it to becoming suspicious and hateful and paranoid, and see how it damages Rhaella and Aerys and their overall relationship. I want to see Rhaella gradually become increasingly afraid of Aerys as time passes, and I want to see Aerys' increasing distrust, paranoia, and sexual abuse of her and I want to see how Rhaella copes with it.
I want to see Aerys as a father to Rhaegar, who was his and Rhaella's only surviving child for a long time. I want to see Aerys obsess over his children, living and dead. I want to see Aerys order his son's wet nurse to be beheaded and torture his mistress and her family after blaming them for his son's death. I want to see Aerys's Kingsguard standing constant vigil around baby Viserys. I want to see Aerys and Rhaegar's rift after Rhaegar marries Elia, Aerys refusing to welcome little baby Rhaenys, and the growing rift between those who supported Aerys and those who supported Rhaegar juxtaposed by Aerys arresting and brutally executing Brandon Stark, his friends, and their fathers after Brandon demands Rhaegar to "come out and die" after Lyanna is taken/kidnapped/runs away with Rhaegar. I want to see what Aerys thought of the still unborn Daenerys, what little he could have known of her.
I want to see Aerys during Robert's Rebellion. I want to see Aerys become more obsessed with fire and wildfire, and using it. I want to see him and Rossart, Varys, and Pycelle. I want to see him become more and more paranoid and sadistic. I want to see his mental state be consumed with "burning everyone and everything" after Rhaegar is killed, with the belief that he will become a dragon. I want to see Aerys agree to Tywin and his forces into King's Landing. I want to see Aerys become the man Jamie knew and his death at Jamie's hands.
I want to see Aerys become a monster. I want to see the optimism and prosperity of his youth and early reign become horror and fire and blood.
