CHAPTER 1:
Hell's highway
Whatever Petunia thought death was, it wasn't that. Not a full void of... nothingness. She was "floating" in it, merging with it. There was no up and down, no sensations, no body, only her thoughts, her conscience. And her pain.
Her mind, now free of external distractions, was running like wild horses. One thought pulled another, an another, mixing them without any kind of order or logic. One memory brought another, and then another, without apparent connection. She couldn't speak, couldn't do nothing to stop this maddening stream of memories.
Dudley throwing a tantrum, Vernon asking her to marry him, she slapping a teen Severus, Lilly saying how disappointed was with her...
One moment... Petunia concentrated on that memory. Lilly never said that to her! It was no real!
And there was she, Lilly, her beautiful sister. Her green eyes were looking at her with compassion and disappointed. The perfect Lilly, the bitch!
"Why, Petunia? Why did you do it?"
Petunia was at loss for words.
"If our roles were switched I would have raised Dudley like my own son."
Something inside Petunia snapped:
"It's your own fault!", she raged. "You, and your freak husband! Blown up by a maniac! A maniac that cost us our very planet! Freaks! Monsters!"
There was sorrow in Lilly's eyes.
"Two bedrooms, Petunia. You had two free bedrooms and my son was "forgotten" in the cupboard under the stairs. He was only a baby, Petunia. Who is the freak? Who is the monster?"
"It's all your fault!" screamed her, at the top of her lungs. "It's your bloody fault!"
Lilly vanished and was replaced by her mum, freezing Petunia rant.
"I am disappointed in you, Petunia. We raised you better than this."
"It's your fault!", repeated her in denial. "It was always Lilly, the perfect daughter! Lilly, the witch!"
Her mother watched her with pity.
"And you transferred your petty jealousy to an innocent boy. Family matters, Petunia, or did you forget?"
Speechless, Petunia could only see how her mother changed into Dudley.
"Dudders...", was all she could say between sobs.
"Harry was neglected but you mistreated me more..."
"Dudley!," screamed Petunia flushed. "That's not true! I love you more than life itself!"
"Yet you never tried to teach me right from wrong. You never reprimanded me, always putting the blame in other people."
"But you grew up to be a good man!", protested Petunia sobbing.
"No thanks to you. Sandra was the one who did it. And you tried to break us apart."
"She was no good enough for you!"
Dudley didn't respond. He simply banished in the nothingness, like a ghost.
"Why!", screamed Petunia in the void. "Why are you doing this to me!"
"Because they love you, you stupid fool!", answered a known voice. A young Severus Snape appeared in front of her, looking down at her with contempt.
A speechless Petunia could only gawk.
"I don't know why they try to save your soul, you pathetic worm! You only reap what you sow. And you only brought misery, for your nephew, your sister and your son, you brainless jealous tart!"
He sneered at her and Petunia broke down crying, hiding her face in her hands. No, it couldn't be! It was not her fault! It was all a nightmare, a bad dream!
"Behind all the farce of normality that was your life, Petunia, there was a hateful marriage, a bully for a son and a slave for a nephew. That is what monsters are, Petunia. Freaks are people like you, who hides behind a proper look of normality to do harm." The voice of her father brought her back to the reality.
She looked at him, seeing his disappointment. It hurt more than anything. She tried to speak, but could only let out a strangled sob.
"But you don't understand, do you?" His voice was only a whisper, but Petunia heard it anyway. "You will not accept it, even when you know it is true."
"Dad, I...". She tried to speak, but her father silenced with a warning look. With a sigh, he seemed to give up.
"Wait!", screamed her. "Please! I am sorry!"
He re-appeared, his expression soft.
"Would you suffer the consequences? Would you amend it?"
"Yes! Please!", she cried.
He looked at her with his green eyes, Lilly's eyes.
"Let the punishment fit the crime," he said, full of sorrow, before disappearing.
"Let the punishment fit the crime," repeated a ghostly Lilly, looking sadly at her.
"Let the punishment fit the crime!" The voices of her mother and Dudley seemed to break the void.
"Remember, Petunia. You must amend it!", her sister told her. "Some who died will live. She can help you."
"Who?", asked Petunia shaking and sobbing.
The silence was maddening. The voices seemed to vanish.
"Wait... Who!", screamed Petunia at the top of her lungs, feeling alone like she never felt before. Even in the abandoned London, she didn't feel like this.
And old woman materialized before her. Her eyes full of regret, hurt Petunia more than anything. Her musical voice brought some comfort to her tortured soul.
"You must find me. Find me and I will help you."
And Petunia woke up creaming.
