Aberforth looked down at his sleeping brother, the pain potions and laudanum plunging him into a deep sleep after such a tormented birth. The baby in his arms was also asleep, wrapped in a simple blanket made by Lady Batilda.
"What shall we do with the child?" asked Mrs. Bagshot.
"I have a friend who is going to America," answered Aberforth, rather it was his former mistress, "She lost her baby, it was stillborn three days ago, we can give the baby to her.
The dead baby was Aberforth's, he looked down at the baby in his arms. The child of Albus and Grindelwald, Aberforth hated that manipulative git had managed to entangle Albus two years after Arianna's death at such a vulnerable time as his heat.
It was simple, an omega like Albus could so easily fall into the clutches of a narcissistic, self-important Alpha like Grindelwald. He used it and again he left, leaving his brother pregnant.
Aberforth must have poisoned him when he had the chance.
"What will we tell Albus when he wakes up?"
"The logical thing to do, some babies die within minutes of birth. Cot death" Aberforth passed the baby to Batilda.

When Albus woke up his body felt like lead, in an unconscious movement he ran his hand over his belly, it felt flaccid, less bloated. Albus's mind began to spin, his baby.
His baby. Where was his baby?
He got out of bed, his legs still sore, and carefully walked out of his room and into the living room. Aberforth was sitting by the fireplace smoking his pipe.
"Where is he?" asked Albus catching his brother's eye, he turned to look at him and walked towards him. - Where is my baby?
"You need to rest Albus. It was a long labour."
"I don't want to rest. I want my baby. "
"Come on, Albus," his brother gently took him by the arms and they went back into the room.
"What about my baby," Albus sat down on the bed. "Who has him, Mistress Batilda, did she tell Gellert of his birth?"
"Albus," Aberforth placed both hands on his shoulders, "You should know this is not your fault, it happens so often."
"What is it?" He looked him straight in the eye and knew, "No. No. No. No. No!"
Albus got up from the bed but was held by Aberforth in an immobilising embrace, he kept moving aggressively and let out a piercing scream, the mirror in the room shattered at the abrupt expulsion of magic.
"He was small, very small."
"But he cried. His cry, it was the cutest cry in the world." cried Albus, tears quickly wetting his cheeks "He was alive, I felt it. He cried, he cried."
"The midwife said his lungs were not strong enough. "
"My Aurelius, Aberforth. My baby is dead."
Albus mourned the death of his baby for days. He had hoped that with his birth Gellert would come back to him, they would be a family. He cried, looking at the little boot with all the baby clothes: sleepers, bonnets, little mittens and booties, all knitted by him.

Albus looked at his brother, he couldn't look him in the face. He lied to him for 30 years, years that he had been away from his son, from his soul.
"Why?"
"It was for the best."
"It's my baby you separated me from."
"And his father is a monster you used. That blood pact is your complete ruin. Did you think you and Aurelius were going to be the perfect happy family?"
"You had no right!" Albus shouted at him. "This is my son we're talking about. I don't know what kind of horrors he went through in his childhood, and now Gellert is using him as a weapon without knowing he's his own son!"
"And even if he knew it was his he would do it anyway, Albus," Aberforth replied.
Albus breathed heavily, he had to find his son and bring him home.

"I am not Aberforth's son? I am not a Dumbledore" Albus's soul broke at the sight of his son, his magic felt sick, weak, dying.
"You are mine and Gellert's," Albus replied, hugging him, "You were taken from me, they told me you died moments after you were born.
"I'm dying," sobbed Aurelius, Albus stroked his hair.
"Let's go home, no matter the time, let's be a family."
And so they both took the shuttle to Hogsmeade.
