Things had been relatively calm these last few weeks. Although there was a feeling of negativity over and over again, he figured it was just a Frisk or Chara that preferred genocide runs or something. Nothing new, per-say.

The difference here, was that the negativity felt different than normal. Usually, the negativity is from one of the humans, but this seemed to be from a monster. Not only that, it seemed to be specifically from a sans, and there was a lot of negativity constantly coming from him. At first, he wondered if it was an au where the roles were changed, but that didn't excused the strange negativity. So, one day, he decided to check it out.

"I'm heading out!" Nightmare yelled out, heading to the main doors. "Where going?" Horror asked, and Nightmare turned to see him sitting on one of the chairs, chewing on a fat wooden stick that he probably got from the castle's 'garden'. There were a few plants, but it didn't scream 'royal garden' at all. "I've been sensing some strange negativity lately, so I'm going to check it out." Nightmare stated, and Horror's eye brightened in response. "New family!?" Horror exclaimed. Nightmare sighed, and was going to refute by denying it, but Horror had his puppy dog eyes up, which, to normal people might looked like Horror was looking at them like they were prey, but to Nightmare who knew what the eyes meant and who has been living with Horror for a little while... he couldn't help but feel the effects. "I.. don't know. Maybe." Was all Nightmare managed to say, looking away from Horror. He seemed to brighten at this, and went back to chewing on the stick happily.

Nightmare left through the castle's doors, letting out a sigh. He didn't need to leave through the doors in order to go to other aus, but it let everyone know someone has left, as the doors were quite loud. Plus, it was just polite and common courtesy to leave before teleporting away... maybe Bones was rubbing off on him, Nightmare thought, before leaving to go to the strange au.

When Nightmare arrived, it was near the end of a genocide route, and the sans was killing the last few monsters. Nightmare followed his surging negativity, and found him killing the final monster, before looking up at the dust-filled sky. A button shone in front of him. "Again." Was what he said, before the crunching of snow was heard. They whipped around to see Nightmare, who was not even trying to hide. Nightmare got a good look at him, and quickly understood the strange negative feeling. His SOUL didn't even seem monster anymore, it was mixed in with determination, and negativity was leaking from his eyes. If he, no, since he killed these monsters so many times, the determination must've only gotten stronger, and so had the HATE. Nightmare was negativity, while HATE was a subcategory. Even so, Nightmare wasn't just HATE, and his negativity didn't control him either. Here, the sans seemed overcome with HATE, and wanted more, or, at least, he seemed to crave for something. What that something was, Nightmare could probably guess, looking at the Chara hovering over his shoulder.

The hate-leaking Sans hesitated, taking a step back, he could tell Nightmare was strong. Chara's grin widened, and the SOUL(?) brightened. Then, the sans' smile widened as well, as HATE continued to pour. "A new plaything?" Was what they said, Nightmare's nonexistent eyebrow raising at the comment, or, it seemed to be more like a question. "I am sans." The sans said, grin widening, and getting into a fighting stance. They were excited, Chara telling him to hurry up as they sprang towards Nightmare on command. He couldn't help but politely answer back. "And I... am Nightmare." Nigthtmare said, his tentacles sprouting from his back as his did so. The two's grin widened even more, somehow.
