I remember scrolling on the internet and reading some discussion of characters being gentle with kids and I thought about how Harry would deal with kids in similar situations like his.
So here is my take on the idea. Enjoy!
Of all the missions Harry could get as auror, this was his least favorite. For it always served as a painful reminder of his childhood.
Knocking on a house's door in a plain-looking muggle neighborhood, Harry could only frown when a stern-looking man opened the door. He looked at Harry, who was dressed more like a muggle cop, in disdain.
"Can I help you?" His gruff voice asked.
Harry took a deep breath before answering, "As per your request, I'm here to take Timothy Louter-"
" It's no Louter."
It took every bit of willpower in Harry not to throttle the man. Though Harry did not mind letting his magic slip a little and cause the muggle to step back. Harry heard a crash in the background and Harry hoped the wife broke something.
"I am here to take Timothy to his new home." Harry stepped into the house. "Where is he?"
"Listen here you freak! I won't-"
Something in Harry snapped as his wand popped out of his sleeve and into his hand. The man found himself silenced and petrified. Only the rapidly shifting eyes showed his panic. Harry snapped his wand to the wife and similarly had her silenced and petrified.
As much as Harry wished to let out his magic and just scare these two muggles to death. There was someone that took higher priority. Waving his wand, Harry found a small red light in the basement.
Everything in Harry screamed to blast this house and its owner apart. Yet, Harry did not give in to that impulse. Instead, with careful quiet steps, Harry found the door to the basement and began to descend. In the corner of the basement, there was a door that had some light peeking from underneath it.
Standing in front of the door hand raised to knock, Harry found himself hesitating. Squeezing his eyes shut, memories Harry would prefer to forget raced by. Forcing his eyes back open, Harry knocked gently on the door.
"Come in…" A small voice quivered.
Slowly Harry opened the door and stepped into the room. The first thing that stuck out to Harry was how empty it was. Just the bare necessities to get by. Something shifting in the corner caught Harry's attention.
Harry felt his heartbreak a little when he saw a small thin boy hiding in the corner with the thinnest blanket. The file said the boy was eight, he looked closer to six.
With slow and obvious movements, Harry kneeled in front of the boy. The boy watched closely, his eyes following even the smallest of twitch.
"My name is Harry Potter," Harry said barely above a whisper, "I'm here to take you to a new home."
The boy said nothing as he just stared at Harry. The blatant fear and distrust in the boy's eyes were all too familiar to him. The same eyes he had when he was just a boy too.
Harry shifted so he was sitting cross leg infront of the boy. The boy watch closely as Harry put his hand behind his back and when it reappeared holding a stick.
"This is a wand, with it I can do magic. Would you like to see?" Harry asked still speaking softly.
When the boy nodded, Harry held his wand high above the both of them and began to twirl it in the air. At first, nothing happened until, a twinkle. Then another and another. Soon the room was filled with twinkling lights as a dark expanse spread out behind them. As the starry night sky continued to spread across the room. Timothy's expression changed to one of wonderment.
"Can I do this too?" Timothy asked in a soft raspy voice.
"One day you can do this too. It might be hard to believe. But I was once a lot like you." Timothy stared at Harry with disbelief. "It's true, had a little closest underneath the stairs where I slept. I was a lot older before someone finally took me away from there and told me I could use magic. Today, I want to be the one to take you away from here."
"Can you really?" Timothy asked dropping the blanket.
Harry simply nodded his head and held out his hand. Timothy tentatively reached out and took hold of Harry's hand.
"It's warm," Timothy whispered to himself. The broken parts of Harry's heart shatter some more at the small innocent admission.
Harry slowly stood and helped Timothy stand as well.
With a gentle smile, Harry led Timothy out of that small bedroom. While Harry hated missions like this, they were also his favorite for Harry got to be the hero he never had.
