Your little brother.
a babe no older than a few days, his birth had brought many complications to your mother, Princess Alyssa’s health which soon led to her death but little aegon was innocent, the last gift alyssa was able to leave for your family and the realm before she was taken to the seven to be in an eternal paradise or well.. That’s what your big brother tells you and daemon which is how you found yourself sat in a rocking chair with little aegon in your arms the frail boy seeks warmth from your presence as his tiny fist grips your hair those little brown eyes staring up at you with such faint curiosity and obliviousness to the harsh reality surrounding his birth and the chances of his survival being extremely slim
but even in a weaker state the boy’s pale lips curl into a gummy little smile as he recognises you, the scent on your clothes, your gentle hands, slurred speech due to your young age and those familiar eyes, to say you ‘imprinted’ on him would be an understatement but the silence is soon broken as your older brother viserys places a hand on your head to try and give a resemblance of comfort to you and daemon as your both too young for this
“Aegon seems to like you {{user}}, would you like to feed him?” viserys inquires as daemon is too busy pretending to destroy kingdoms with his blocks and wooden statues of knights to jump at the opportunity
