What was around them was the remains of experiments. Wrong experiments, ones that had hurt Sans all of those years ago.

Experiments that Sans never told him about.

Not only was Sans and Papyrus created in a lab, Sans had killed someone. The fact of killing someone wasn't what bothered Papyrus, the scientist deserved it. What did bother him was that Sans never told Papyrus any of it. Didn't Papyrus deserve to know?

Or... maybe Sans had been protecting him. This kind of experience would leave someone shaken, there was no doubt that this knowledge would have made Papyrus second guess everything bout himself as a child. It would have interfered with everything, making him question his own existence.

Papyrus could only stare at the screen with an expression of surprise, no words left in him. What could he even say? Everything about his life and his own brother had been a lie, right down to his birth.

This entire situation made his head swirl with confusion and grief. Sans had been a murderer this entire time. He had been suffering in silence his entire life, and Papyrus did absolutely nothing to help.

If only Addy could talk to them. Papyrus wanted to ask her questions, but she simply watched them during the silence. Everything hurt for him, he felt like he was drowning in an ocean.

Everything was a lie. Everything.

Walking back felt longer than walking in, the doors taunting the tall skeleton as he walked past. If Sans hadn't done that, what would they be like now? Would he still be in pain, being tortured everyday by that faceless man? Or would Papyrus have stepped up, ending the man himself?

If Papyrus was in Sans' situation, would he have done the same thing?

As a child, Papyrus had always claimed that killing was wrong. No matter the situation, Papyrus would say there was an alternative to killing, that anyone could be a good person if they just tried. He had always associated killing with bad people, thinking that only bad people could hurt others.

But now, that belief had been thrown out of the window. There wasn't good and bad people, that was just a label people used. No one was truly good or evil, and not everyone had choices to be either way. What Sans did wasn't wrong, even though he had killed someone, he did it for self defense. It was obvious that the man wouldn't be swayed with words. If Sans had to ask permission to cry, then be denied of a natural right such as that...

If Sans hadn't killed him, Papyrus couldn't deny that he may of.

This also explained why Sans never really used his magic around Papyrus. It had always been small bits and pieces, never using any attack or defense magic. If Sans had been given that much determination, that meant he would probably be powerful. Just as his children confirmed. And if Sans had used that power without any known sources, Papyrus and other monsters would start pushing questions that Sans wouldn't be able to answer.

It all finally made sense. Why they never had any parents, why Sans never took any scientific jobs even though he was good at it. He had only taken one when Papyrus was in high school, and even then it was one over the computer where Sans didn't have to go to the labs. At the time, Papyrus had pegged it as his brother being simply too lazy to leave the house, but now he could see it was a more deep seeded fear of the lab.

Papyrus didn't have all of the answers. He had no idea how they had been made, or some of the things the man was talking about. He seemed adamant over some approaching deadline, and some other things he said made no sense. But he had enough to get a clear picture of the truth lingering under the fabric of lies the world had woven during his lifetime.

Just looking at the door labeled Sans made vomit build in Papyrus' lack of a gut.

That was where he probably spent most of his time. On the cold floor, with no one to hug or even talk to. That could have been Papyrus too, if Sans hadn't saved him.

All of that time, and Papyrus had owed Sans so much. His brother raised him, took care of him, protected him from the truth to their origins.

And Papyrus had turned him away when Sans needed him the most.

Addy must have noticed Papyrus' thought, as a small hand suddenly grasped his. And sure enough, there she was, quietly encouraging him with a large smile.

At least Sans had found happiness with a new family. That was something that brought Papyrus comfort.

"Heeeeeeellllllllooooo gays!"

Now, Papyrus wasn't really sure where this boy had come from. One moment the group had been walking out of Alphys' old lab in silence, and the next there was a tall boy with a big smile frantically shaking Papyrus' free hand.

The new person resembled Silky, with tall and lean limbs, his arms stretching down well past how long arms on a person should be. Pure white skin was pulled over his thin muscles and bones, and he was rather tall.

However, he had a different style from Silky entirely. His overalls were a bright blue with his shirt a mint green color, a bright red bowtie stuck to the front of his shirt. Colorful yellow smiley face pins were stuck to the edges of his sleeves, pinned in through the mint colored fabric. A large pair of round glasses sat on his nose, pressed against his large eye sockets. Glowing white eye lights barely even scanned Papyrus as the boy rapidly shook his hand, a pitch black mouth pulling back into a large smile.

"Hi, hi, hi!" The boy said, eagerly shaking his hand. "It is so fantastic to meet you that I'm going to throw up! Excuse me for one second because I'm going to do just that!"

He suddenly turned, grabbing a nearby trashcan stationed outside of Alphys' lab and pulling it into his chest before he instantly started throwing up inside of it. It was especially awkward for Papyrus, who the boy continued to shake hands with while he used his other hand to hold the trashcan. After he was done, the boy simply tossed the trashcan over the railing into the lava below before he turned back to Papyrus.

"Hiya Addy!" The boy giggled when he took notice of her, waving at her with his free hand.

Addy quickly let go of Papyrus' hand before running up to the new boy, pulling him into a hug.

"Aw, you look so adorable in your little new sweater! You have to let me braid your hair later!" He giggled before he glanced back up at Papyrus. "But hiya there, it's so fantastically great to meet you! You're Uncle Papyrus, right? I just know you are! You're also gay, by the way!"

"Are you BoBo?" Papyrus asked the boy.

"Yesaroo! You're so smart, it's awesome to be related to you!" BoBo said, finally letting go of his hand. "Who are these two lovely lesbains?"

"I'm Undyne, and that's Alphys..." Undyne introduced herself slowly, "She's my wife-"

"I knew it! Aw, you two look so cute together! You're practically soulmates!" Bobo gushed, his eye lights practically sparking. "You guys repressed your feelings towards one another, because you were both afraid of rejection! That is so romantic and cute, I can't handle it! I might throw up again!"

"P-Please don't," Alphys muttered.

"How come you can tell that all of us are gay and lesbain?" Undyne asked.

"Oh, sorry, sorry!" BoBo said, "I can tell sexuality on sight, it's just my thing. Anyway, would you like a smiley face pin? They're adorable and cute and shiny."

"I'm good," Undyne said.

"Aw, okay." He sounded disappointed. "But that's fine, because I already know that I'll be living with you guys because Silky told me so I'll just put them on while you sleep!"

"What?" Alphys asked.

"Silky told me everything just now, and Leonie told me some things while we were playing bed wars." Bobo played with Addy's hair as he spoke before he moved a hand up to his shirt pocket, pulling out a bundle of colorful bracelets. "I also made friendship bracelets!"

"That won't be needed right now," Silky said, appearing next to BoBo and Addy.

BoBo gasped, looking at his sister with offense. "Friendship bracelets are always needed!"

"It would be better to save them for a later time, such as when we arrive back at their house. Leonie has collected all of her electronics, so it would be best if we left as soon as possible. The demon proxies may have the underground on watch, so it would be best to leave quickly."

"Okay, but I have to tell you guys so much since I've never met you before!" BoBo said, clapping his hands together. "So, it started on the day of my egg hatching..."
