Soulmates

One

A dark rimmed portal opened up in a dead AU. A black skeleton jumped through the portal and landed in the Snowdin area. The snow having a grey tint to it due to all the dust.

Nightmare looked around the AU, feeling confused for a moment. He had felt a large amount of negativity in the AU and decided to investigate but.... there was no one?

He looked around and spotted the skeleton's house and went there. He turned into a shadow and snuck inside, looking around.

Killer squeezed his eye sockets shut tightly, shivering in pain. He whimpered quietly, clutching his shirt just above his Soul tightly.

His Soul hurt so much.

Nightmare's eye sockets widened when he saw someone and turned solid. He stepped forward, gaining the skeleton's attention.

"Are you alright?" he asked the skeleton softly. He couldn't let this skeleton suffer. Maybe... maybe he could give mercy? There was no one around.

Killer gasped in pain as he looked up. A dark skeleton was standing there, one blue eye glowing brightly in the darkness.

"It hurts..." He gasped, his voice laced with pain as he held his shirt tightly.

Nightmare flinched. He didn't expect the skeleton to say that when he was not doing anything. Maybe... maybe he could help? Help someone for once. He couldn't... he couldn't let this skeleton be in pain.

Nightmare ignored the burning pain on his arm as he walked towards the skeleton. "Hey, it's okay. It's okay. Tell me what's wrong?"

"Please take it away, please, it hurts so much." Killer said, his arm hurting a bit more than normal.

He choked on a sob, curling in on himself.

Nightmare approached the skeleton, talking calmly in a soft kind tone. "What hurts? What's wrong?"

Killer sobbed, tears rolling down his face.

"My Soul hurts..." He cried out in pain, shivering harshly.

Nightmare paused at that. His Soul? There was no sign of any physical or magical problems. So...

But... it was risky. He couldn't-

"Argh!" Nightmare yelped when his arm burned, holding the area in confusion and pain. What's happening?

Killer sobbed as his arm burned harshly, overshadowing the pain in his Soul.

He dragged up his bloody sleeve. Had some scars opened up again?

He frowned when one of the sentences was finally gone. Had he finally succeeded?

Nightmare hissed and pulled back his sleeve and watched as one of the sentence glowed and slowly disappeared like it was being burned off. It was.... disappearing?

W-what? Why? Had his Soulmate died? Or...

Nightmare looked up and saw the skeleton doing the same thing he was doing. He was also holding his arm. He had... three sentences. Just like him....

Was- was he-?

Killer winced.

Why was it disappearing? Why that sentence? It had helped him so often...

He stared at his arm blankly as it burned, some of his self-inflicted injuries still bleeding a bit.

Nightmare watched, transfixed as the mark on the other skeleton slowly disappeared. He ignored his own pain, directing his attention to the other skeleton.
