A young woman crouched down on the nearest roof, watching as a young boy was made to pull weeds out from the garden, he was malnourished, and from the faint scent of him, he hadn't had a proper bath in weeks, ears twitching, the woman knew what she had to do, and she didn't like it. She raced back to her den, she couldn't stay here forever and if she was going to kidnap a kid in the dead of night, she needed to pack a few things.
She learned a few things during her years among the humans, she related to the Evans' Family and that Petunia Dursley nee Evans was an idiot, who didn't understand magic, who had no magic and didn't want anything to with that or any person, related to said subject.
She packed up her stolen goods, and left never looking back, she went and jump the fence to the Dursley property, she heard the boy, who was forced to sleep in the shed that night, she opened the door, her night vision located the boy, she placed a blanket over him, and lifted his bony frame up and exited the shed, jumping the fence with ease again, and leaving without a trance.
She looked down at the six year old in her arms, "I am sorry, I didn't find out sooner, but I will atone for your mistreatment."
