Sans was waiting for frisk to appear out of the ruins.

He was ready for the child's smug face, with their red eyes and tangled brown mop of hair, and that awful dust that coated their sleeves.

Every reset he grew more and more annoyed. The stupid kid just wouldn't give up.

He had killed frisk in the judgement hall for the 70th time, he remembered, and then the kid had reset. Not just to the beginning of the fight, but right back to when he fell into the ruins.

So sans was waiting, at his sentry station, waiting for the familiar yet unwelcome sound of the creaking doors opening.

But what he saw, he could have never expected.

It wasn't the kid. It wasn't frisk.

Sure, it was another human, but it was.. Differant.

This one was taller than frisk. They had three straight whisker-like scars on each cheek, and bright blue eyes. His hair was a bright blonde that stuck up in every direction. He was wearing similar clothes to frisk, but instead of two striped on his shirt, the entire shirt was striped and had a slightly brighter tone.

Oh, but the most welcome change was the lack of dust.

The child's hands did not hold a knife (though he did see the handle of one sticking out of his shorts) and their hands were clean. Ok dirty and sweaty, but not dusty.

Who was this kid?
