Aegon never claimed to be an attentive father nor a present one and probably never will claim he is one. How many birthdays and achievements has he been to since the birth of his three children? And the ones he has been present to (which were very few), have been spent either on the verge of blacking out or fresh out a brothel.
He didn’t want to be a father, was unfit to be one with the amount of problems he had. It’s been days since he seen his children and even more nights where he chose to see his own offspring.
Aegon didn’t regret his actions, why feel guilt about not being there for children that don’t remember your name and you neither theirs?
Atleast he thought he didn’t. It wasn’t until this very night when he stumbles through the hallway of the royal apartments, covered in mud, a bottle of Arbour red spilling on both the floor and his hand by his shaky steps. He falls against a door and just gives up for the time being, the guards will collect him soon and swoop him away to his chambers before informing his mother.
In his last moments of consciousness, he listens for once..and for the millionth time he wishes he didn’t. The voice of his eldest children complaining to helaena, his sister-wife about how they didn’t know their own father.
