Killer POV:

I woke up in the middle of the night. I immediately realized I was overheating. I sat up and pulled my blanket off. It didn't help much. I checked the time. It was just before Nightmare usually woke us up for school. I was sick. I laid back down. I was not comfortable at all.

"Killer, It's time to..." I heard Nightmare open the door and begin speaking. He must've seen how I looked when he trailed off. "Are you sick?" I weakly looked at him and nodded. "I'll get you some medicine after I get Horror and Dust off to school." He closed the door and left me sickly sitting on my bed, overheating.

~Time Skip~

I had wandered out to the living room because of boredom. Cross was still sleeping. I was watching cartoons and nibbling on some chocolate that was probably Cross's.

"Still want some medicine?" I jumped when I heard Nightmare's voice.

I looked up at him and nodded. He walked off. I yawned. I just wanted to keep watching cartoons. He returned a moment later with a bottle. I watched him pour it into a tiny measured cup as I sat up. He handed me the cup. I looked up at him.

"It's medicine. It'll make you feel better." Nightmare said.

I drank it. It was sort of thick. I swallowed it.

"That was weird." I commented.

"You should feel better though." Nightmare replied.

He sat down beside me. He grabbed a blanket and wrapped it around me. I was a blanket sushi. I giggled. Cross came out and joined us a few minutes later. He became a sushi too.

As some time past by, I didn't feel any better. I just felt more sick.

"Hey Nightmare?" I asked. He looked down to me. "I feel worse than earlier."

"Do you feel like your going to throw up?" He asked.

"I don't know." I honestly replied. I didn't feel good, that was for sure.

Nightmare POV:

I didn't know what to do. I've never encountered anyone getting sick before. I can't get sick, Error can't get sick, Passive is dead, so he can't get sick. But he has been sick before. 'I need to ask him.'

"I'll be right back." I told the kids.

I got up and walked to my room. I went into my bathroom. I turned on the water and splashed my face. The right side, specifically. It stung. I waited until it was completely gone before opening my eye...s.

"Oh. Did you need something Terror?" I heard Passive's voice echoing through me head again.

'How do I take care of a sick child?' I asked him with a thought.

"Why?" Right. He's probably been in the library this whole time. I put a towel against my aching head.

'Killer is sick, and I have no idea what I'm doing. The medicine also did nothing for him.' I explained.

"Huh. I'd have to see him. Maybe I could help you then." He said.

'Your vision makes everything look like blurry potatoes.' I reminded. He laughed.

"Right. I still need to try and hear him at least. There's colds, flu's, and fevers are the most common sicknesses." He explained.

I started walking back to the living room. I arrived and leaned over the couch.

"Hey, Killer." I said.

"Need anything Nightmare?" He asked. He started coughing a moment afterwards. He stopped after a few seconds.

"Oh..." Passive remarked

'So? Which one does he have?' I asked with a thought.

"Either a cold or a flu..." Passive trailed off.

'But he's overheating too.' I reminded.

"Nightmare?" Cross's voice snapped me back to reality. "Why'd you show your other eye again?"

"I needed to ask my ghost something. I can only hear him like this." I explained.

"I don't know!" Passive suddenly shouted. "Granted Dream only got sick once and healed super fast. I also got sick once. Mine lasted a whole. Dang. Month."

'Don't start rambling.'

"Sorry Terror." Passive apologized. "Still, most likely for Killer seems to be a flu." He continued.

'Okay.' I thought 'Can you leave now?'

"Nope. You're stuck with me until your goop decides to return."

'Great. But I did give Killer cold and flu medicine.' I thought as I sat back beside the kids.

"Huh. Now I'm lost." Passive admitted. "I'm not an expert on sickness. Since I did kinda die when I was six. To someone."

'Shut it.' I thought, annoyed.

~A Week Later~

Killer had gotten worse. We were all worried. Horror hardly left Killer's side. I scheduled Killer an appointment with Sci, and it was fast approaching. I walked into his room. He just sat asleep in bed. I shook him awake. Killer barely woke up and looked at me.

"Doing okay?" I asked. Killer nodded at me weakly. "We gotta go to the doctor." He groaned.

I scooped him up. I had splashed water on my face again earlier so Passive could talk to me. To be honest, I wanted his advice.

We arrived a few minutes before. Killer was asleep again against my chest. I was getting worried. He wasn't doing well.

"It'll be okay." Passive said gently in my mind.

'You better be right.' I told him.

Sci pretty much told me Killer had *insert illness*. He prescribed Killer some antibiotics. As long as he took them, he should be okay. I thanked him and took Killer home.

I needed to be sure Horror didn't develop any symptoms either. I had Killer take the first dose of his medicine. He had water near him to wash down the taste.

"You should actually get better now." I told him. He nodded. I rubbed his head.

"Thanks...Dad." He said rubbing his eyes.

"I-uh..." I had no words. He called me dad.

"Oh! He considers you his dad!" Passive suddenly squealed.

Killer seemed to notice his mistake and covered his face in his blanket. I chuckled. That made me happier than I think he realized.

"Just ask me if you need anything. I'll come back when it's time for your next dose." I told him, getting up to leave. "And thanks. The dad thing was nice." I left quickly.

~Another Time Skip of a Week~

Killer was getting better and Horror didn't seem to be getting sick. That was good. We hadn't told anyone about the dad-thing. That was just between us right now. I was making lunch for Cross and Killer right now. Horror and Dust had brought back the homework Killer had missed, so he was doing that.

"I finished-" that sentence was interrupted by a cough "-It." The forever-crying skeleton finished. I chuckled.

"Someone's feeling better. And good job. That only took you about an hour." I congratulated. He smiled proudly. "You should be able to go back to school soon." He glared.

"Why must I?" He asked

"Because it's not fair to Horror and Dust. And you can't move one to First Grade with them." He gasped.

"Okay I'll go back!" He said before running off. I laughed. Kids are silly.

I am very glad that Killer is okay now though. The kid scared me there for a moment.
