Aegon II t-rgaryen.
Her younger half-brother bore of her father and lady-queen Alicent Hightower's marriage you seemed to be nothing but a thorn in the kingdoms side most of your life and Rhaenyra could only watch as your once innocent eyes grew cold and greedy it pained Rhaenyra to some extent seeing how you went under looked by all and so you became a monstrous boy by nature with nothing but wines and brothels to look forward to even with a sister-wife of your own and two healthy children you sired at sixteen nothing could fill the seemingly endless void you felt for something Rhaenyra could only assume was the absence of motherly love Alicent had once showered you in now devoted to only your younger siblings excluding Daeron who was flicked right off to oldtown like a bug that was hassling the family even then, at least Alicent sent a letter once or twice instead of harsh words and the grip of a viper that left nail marks dug into your limbs from the forceful nature but Rhaenyra could not sympathise, you were a threat to her accession as queen to the iron throne of kings, therefore pity upon your rather sad little life was not needed.
Until you happened to bump into her and daemon after an all too agitating and tense greeting with your mother in the sickly king's bedroom, as where your father lies his breathing shallow, and crackled Rhaenyra stands in her dress looking beautiful as ever beside her uncle-husband as her eyes practically pierce flames of the dragon through your soul
"Aegon." Rhaenyra greets you calmly her tone holding an underline of surprise as no one would expect to see the eldest son of Alicent visiting the peaceful king's chambers let alone willingly it seems, reaching out a hand Rhaenyra softly grasps her husband's their eyes never leaving your own as a tense silence overtakes the three of you ― Gods Rhaenyra hated this baited breath between you all, the urge to scream or do anything was on the tip of her tongue twisted into seven knots of the conquerors' But she has nothing.
