Not all Nightmares are bad (Nightmare Sans X reader)

Chapter 51- Consequences

One by one.

Shattered pieces.

Slowly falling.

Slowly faded away.

Nightmare looked down at the mess he made. Fragments of glass, goo, and heartbreak. Things never go the way you plan now do they, Nightmare. Nightmare told himself. He's not necessarily upset just disappointed. Oh well, that's my life.

"Mom?" Nightmare turned around. That's right, Y/N. He teleported near her. She stated in the ground her nose and eyes puffy. Nightmare knelt over and hugged her.

"I'm sorry." He hugged her tighter. "You shouldn't have seen that." He looked up. Dream was getting up and the kids were baffled. The older ones seemed confused while the smaller ones ran over to him with excitement. His form slowly falling apart.

"Dad!" They shouted in glee. The twins ran over.

"Hi." They both smiled.

"Mom are you okay?" Y/N looked up at them. She smiled softly. She puffed lightly, she slowly started shaking as if she was cold. Nightmare hugged her tighter. "Mom-" Instantly she started vomiting, it was that black substance from earlier. Fuck.

Nightmare in a stride of panic carried her and looked down. He carried her close to his body. He started to head for the door. Nightmare's instinct kicked in. His chest puffed out. He opened his mouth and shouted. "Luna!" He yelled. The dog immediately showed up with the others.

"Master! We managed to regain control of th-"

"You were never told to speak!" He snapped. He glared at her. "I need a medical room, immediately!" Luna nodded her head. This time she kept silent.

"What's happening?" Asked Jupiter. Nightmare ignoring the question looked back at the other three.

"Dusk, get these three to safety! Leo, get two Nightfangs!" The other two nodded. "Mars get this place back in order." With that Nightmare teleported away.

"What's going on?" Asked Midnight as Dusk came over.

"Nothing much young mistress. If you can, please can you all follow me?" Dusk said helping Dream up. Dream flinched backward at the tension he felt, though he was quickly relaxing he felt unsure.

"Here I'll help him." Stated Jason. Having Dream rest on his shoulder.

Dusk nodded. He guided them away towards the door as the twins followed too.

Meanwhile, Nightmare's frenzy continued. Luna approached him, "Master the room is this w-"

"Move." Nightmare said walking past her. Luna gently moved over and followed. "Open the door." Luna quickly came over and opened it.

The room was a vibrant gray and black. The ceiling had a painted night sky. Nightmare quickly placed her on the bed. "Luna retreat."

It was only the two of them. Nightmare placed his boney hand on her head she's hot, not figuratively, actually. She absolutely doesn't have a fever. He touched both her cheeks. She's hot there too. He touched her stomach, there as well.

Nightmare pulled up her shirt to look for the wound. He found it on her right side it was a mixture of black a red. She's been like this for almost an hour. Nightmare quickly placed his hands on the wound. Slowly the light spring green like colors flowed lightly touching the wound. Nothing was happening. It wasn't healing, it stayed in it's cold black state. Nightmare panicked. What am I supposed to do!
