"Are you feeling better now?" Papyrus asked, looking over at Silky.

"Quite," Silky said, "Once again, I apologize for my outburst. I am usually more in control of my emotions."

The two were standing over the sink, both working on cleaning the dishes from lunch. After Toriel had managed to calm Silky down, both Papyrus and her worked on installing the new window before Silky went around to do chores. She said that chores helped keep her calm.

"It's alright, everyone loses control of their emotions sometimes," Papyrus said.

"It's okay for people like yourself to lose control, yes," Silky said, looking at him. "But we cannot. My species is supposed to have control over our emotions generally, especially myself and my Father."

"I was wondering," Papyrus said, putting away a cup, "You keep saying your species, but what do you mean by that?"

"Ah, that is difficult to explain," Silky said, "But I promised you full information, so I will try. You know my Dad, Sans, your brother. But my Father isn't of this world, exactly. He is not an alien, per say, but he's not a natural born earth creature either. He's an entity that came into existence through the void, along with his three brothers. Our species don't exactly have a name, but we are natural born CreepyPasta. Unlike the others, who end up as CreepyPastas, we are born that way."

"It's been such a long time, but I still don't understand what CreepyPasta are," Papyrus said, looking at her. "I know it's horror stories online, but how does that happen?"

Silky paused for a moment, thinking over it. "We aren't exactly sure."

"You aren't?" Papyrus asked.

"I know how my species was born, but CreepyPasta overall is just a name given to us to explain and classify what we are. Uncontained killers."

"But why not be called normal serial killers then?"

"Normal serial killers are humans and monsters who kill just for it, who just so happen to be serial killers," Silky said, "Creepypasta are more unique. People who don't fit in at all, who don't belong on the earth. The unexplainable killers. Children who don't die, monsters who aren't monsters. Creatures with no souls who kill just to feel, people who lived the worst lives and want revenge on the world. That's a CreepyPasta. We aren't normal serial killers, we're much more than that. More complicated and powerful. We have stories that scare people, we're the people who makes even the government shudder. Normal serial killers don't amount to our levels, and we pride ourselves on that. And normal serial killers don't know others, while we're all a family. CreepyPasta are always in it together, even if they hate each other, they're always on the same team. The world screwed each and everyone one of us somehow, and we wanted revenge."

"Then how are you a CreepyPasta, if you have no revenge?" Papyrus asked.

"I'm the part of CreepyPastas that were born into the roll. My Father, SeedEater, things that kill that shouldn't even exist. There's multiple ways to become a CreepyPasta, birth one of them. All of us are CreepyPasta, as we were all born into the roll. Sans, on the other hand, became one. He wanted revenge on the world for hurting him, and that resulted in him killing people."

"After I abandoned him, I know," Papyrus sighed.

Silky looked at him again. "I said I would be completely honest with you on information, so I will. Papyrus, Sans was a Creepypasta before you were even born."

Glass shattered against the floor.

Papyrus had dropped the glass cup he was holding, the glass effectively shattering onto the ground below the two. The sound of the object breaking was deafening, before silence fell upon the conversation.

"Is everything alright?" Toriel called from upstairs.

"Yeah!" Papyrus yelled back quickly.

"You said what now about Sans?" Undyne asked from the living room, Alphys perking up.

Silky looked around, her hair on her head lightly dancing around her face from the movement. "I find the surprise rather unusual, I thought that was rather obvious."

"I don't... what?" Papyrus asked, "How did he... since when...?"

"Dude's been killing since he was younger than Addy," Cole said from the living room.

"Yeah, something about a lab or something." Leonie's teeth smacked loudly with each chew of her blueberry gum. "Took us there I think."

"He did," Silky said.

"W-What lab?" Alphys asked, voice wavering with uncertainty and fear.

"It has nothing to do with your studies, but I did read some of your old papers," Silky said.

"Underground? Y-You mean my notes left underground?" Alphys asked.

Silky stepped away from the sink, carefully navigating her way over the broken glass. "It couldn't even fall in an even pattern," She muttered to herself before she turned to Alphys. "And yes, Mount Ebott. That's where we lived. After living on the surface, the CreepyPasta realized they could utilize the undergrounds lack of life and simply moved down there."

The white haired boy glanced over again. "It's where we grew up, pretty much."

"I-I don't... wha..." Papyrus stuttered, at a loss for words.

They had been there. Underground, no barrier or anything. Papyrus could have drove there, he could have found Sans all this time and-

That was the point. It was such an open and obvious spot that no one would check there. After all, why would anyone want to go back underground? No one thought to even look there, least of all Papyrus. It was the perfect hiding spot for someone running from their family and the police. Already housed, already farmed, already furnished. All it needed was a few hands to maintain the core and a small group of people could essentially live down there forever and never come to the surface. It was a perfect place.

That Papyrus never even considered.

"He took you all underground?" Undyne asked Jeff.

"Yup, it was right after you had healed him," Jeff said, gesturing to Undyne. "Our place had burned down and then he said he had been thinking of it for awhile. He took us all there, showed us around, then we set up our homes and boom, that was it. We came out every once in awhile to do things, but really we stayed there most of the time."

"The underground was our home overall, it was how we managed to avoid the police for so long." Silky grabbed the broom and started sweeping gently at the glass shards. "It was also where we were attacked."

"But what about S-Sans and the lab? About him being a C-Creepypasta?" Alphys asked.

"I don't understand... I thought..." Papyrus said.

"I believe it would be best if we went and simply showed you what happened, just as he did," Silky said, "He took us there one day and explained to us what happened, and it would be helpful if you saw as well. We could also explain everything else, and possibly find more ways to track our siblings and family."

"Yeah, BoBo's down there." Leonie continued her loud chewing.

There was a pause as Silky looked over at her sister. "Excuse me, but what?"

"BoBo, he's underground. Said he's been hiding out there with a few of our parents that managed to regroup," Leonie said.

"And you never said this before, because?" Silky asked.

"We're playing bedwars right now," Leonie said.

Sorry for the shorter chapter, I imagine the next one is going to be longer so that one should make up. Testing is happening this week, so we'll see how my schedule changes. 

Also, this video is how I think Slenderman and Silky's skin pulls back:

Basically it's how they eat, and Slenders looks like that. Silky's is a little bit more different, but you get the idea.
