Just a quick warning because this chapter will contain Foreshadowing, mainly about Chaos's past, before she met Error. Enjoy!

----------------------------------------------------------------------------------------------

Chaos stared at the mirror. "What the---" She began to walk up to the mirror. Error had found this interesting AU and instead of destroying it, and he didn't need to, he decided to check it out and bring Chaos with him.

She had wondered off on her own and found a mirror tucked away into a corner. The mirror seemed to be empty, so she had wondered over to it to see why it wasn't working properly, only to see something impossible.

She placed a paw on the mirror, right where a human hand rested. This human was skinny and while her clothes were rags, everything else seemed to be okay. Chaos could see a Frisk and a Sans in the background, along with their friends.

"Who are you?" Chaos asked, taking in the human's familiar brown hair and blue eyes. The human looked like she was about to answer when Chaos heard Error speaking.

"Chaos, come on! It's time to go!"

"Okay, I'm coming Dad!" Chaos removed her paw from the mirror and she left the room behind, never noticing that the human in the mirror followed her movements.

But she never stopped asking herself about what she saw that day, that human, who was she and did it feel like Chaos knew her? She didn't remember anything before she woke up to find everyone asleep in Axetale, so, who was that human?

And why didn't she see her current form in the mirror?
