No one P.O.V

Two people sat in a hospital room, a child sitting on a table who looked at his parents with a confused expression. The parents were disturbed and shocked, the doctor had informed them that the change in the childs skin color was permanent.

This child was no ordinary child...he was now an aubergine. As purple as a fresh and young plum. Maybe even described as an eggplant.

Why this change had happened? No one knew exactly but it's safe to say his parents reaction was anything but good.

Oh I'm getting ahead of myself, you dont even know the childs name yet. The child who sat their on the table was william Afton, son of Ms and Mr afton.

The parents of course got over their shock after a while, telling their son to follow them and get in the car after the Doctor had dismissed them.

Heeding his parent's instructions obediently he followed behind, marveling at his new skin, fascinated and amazed.

This was amazing to be young child and he was excited to live his life as a young little plum. Hee had so many plans of what could happen after this day, dreams, Hopes, wishes for the future.

However the young child did not expect everything to come crashing down on them, their happy mindset shattered as they were thrown from the warm car.

He landed on his back, his back stinging with pain. He looked up at his parent's car with hurt and betrayal in his eyes. "Your a freak now...we could never love a freak..." they hissed to him, his mother slamming the car door before driving off. 

The poor aubergine began to cry as he watched his parents drive off without a thought. He was hurt...beyond that. He was Heartbroken! He thought his parents had loved him and would have loved him even after this strange change.

Knowing he was wrong deep down inside hurt him like nothing else could. 

What he would do from now? He didn't know, but he would find someway to survive out here. He was in New York city for christ's sake!

And with that the newly aubergine child began to explore, looking from place to place for a home.
