The afternoon was peaceful. The only sound that broke it was the sound of giggling. Two figures rested against the golden side.

"Okay, that was funny, Dream." The human said. The skeleton grinned.

"Thanks! I've been having a dream of a time with you." He said. Frisk giggled, not noticing an jealous glare come from the dark side of the tree.

Nightmare sat curled up, listening to his brother make Frisk laugh. Jealousy was an ugly snake. It had bitten him before, but ever since him and Dream had met Frisk, the bites were tenfold.

It wasn't fair.

Frisk preferred Dream over him, just because of the side his brother protected. Nightmare could be funny. Nightmare could be gentle.

Nightmare could...

His eyes landed on the golden apples.

A smile appeared as an idea wormed through his head.

~'~'~

He picked the apple when Dream was asleep.

Nightmare waited until he saw the golden bubble that signaled his brother's sleep. Then, carefully, he moved into the golden canopy. The apples were brighter than his own, sending another spike of jealousy.

But, this would prove everything.

One large one caught his eye. Nightmare grinned, reaching out...

And picked it.

It glowed in his hands, before puddles of black started to spread where his hands touched.

~'~'~

An entire world was destroyed for the love of a girl.

Nightmare stared at the tree that had created him, and at all the black apples. It stood in a land of drought and hunger, where a land of plenty had been.

Dream and Frisk had disappeared. A skeleton that looked like him and his brother, except with a giant paintbrush in hand and different clothes, had appeared and offered Dream to take him to a new dimension.

Frisk had gone with them.

Nightmare growled at the memory, before reaching out and taking a bite.
