Prison was cold.

Of course Undyne was sensitive to the temperature, she didn't like the cold. Going to Snowdin was torture for her, all of her warmer clothes burned in the fire she and Frisk had created. It should have been obvious that the stove was too hot, but the fish monster simply got caught up in the moment, as she often did.

They couldn't keep her forever, she knew the only evidence they had linking her to any crimes was some blood found on her carpet and the word of someone whose name wasn't disclosed to her. How the blood of one of the recently murdered victims get on her carpet? Undyne had no idea, it could have been that one teenage girl, but she never went to that side of the room.

Undyne wanted to talk about this to Asgore, to figure something out, but she couldn't. For some reason she was being walked down the hallway in a pair of freezing handcuffs, digging into her scales covering her wrists. Being the head of the Royal Guard, she gave no fight to the police, understanding just how hard their job was. It wasn't their fault someone had framed her, they didn't deserve to be attacked just because she was confused and upset.

There was already a woman inside of the room when Undyne arrived, sitting across from her on the metal table. With her thick brown hair pulled back into a ponytail, the sunglasses perched on her nose, and that fancy suit, this was obviously more than just a normal police woman. In fact, the people who had escorted her from her cell looked different than the police officers that had put her in there, with more expensive looking uniforms and more series postures.

"Please, have a seat," The woman said, gesturing towards the seat. "Oh, and please, take those silly handcuffs off of her now."

The men moved towards her, one of them pulling out a key to free her from her confines. With a confused glance at them, but not questioning their actions further, she sat down across from the woman.

"I apologize, we had to put you in handcuffs for show," The woman said, "But we are fully aware that you were framed by that blood."

"How?" Undyne asked, "Did someone testify for me?"

"No, but I work with the federal government, I'm a part of the FBI." A badge was pulled out and flashed to Undyne, the woman's hands quick in the movement. "This is a country problem now, and you, Undyne Swimmer, along with Papyrus Font and Alphys Code..."

The woman questioningly glanced down at the paper below her, Undyne trying to sit up straighter to see it as the woman directed her gaze at the two men at the door.

"Are these last names real?" She asked.

"Monsters like to go with simple last names, I know, my last name is kind of dumb," Undyne said, "The monsters picked out last names when they were sent underground, so our last names all a little bit unusual."

The woman nodded. "Ah."

"Mhm," Undyne hummed awkwardly, rubbing her wrists as she waited for the female to continue.

"Anyway," The woman said, "You all are now involved in this. We need your help."

"The human government needs... our help?"

The monster was understandably hesitant and naturally confused, taken aback by the request for her help. Why would the humans need their help specifically? What did this have to do with the blood on her carpet?

"On November 27, you were arrested for evidence and claims against you, along with Papyrus... Font and Alphys Code, as they shared a house with you at the time," She said, "However, you do live across from a grocery store."

The woman pulled out a printed out picture, her tanned hands lightly tossing it across the table for Undyne to see. The picture was light in her hands as she looked at the image, finding her house in the corner. The lights were out, and it was dark, the camera in night vision.

"The store owner installed it a month ago from the increased security needs of our country," The human said, "It has half of your house in sight, and, well, you can see for yourself it caught something."

There was a figure outside of her house, the window of her living room open in his hands. One of the figures legs was being placed into the house, as if he was in the action of climbing in. His back was to the camera, but Undyne could tell it was a male from the body structure, wearing some sort of hood.

"Someone broke into my house to frame me?" Undyne asked.

"It's not just that," The woman said, "You don't understand, this isn't just a country problem, it's global. Japan has lost half of it's wine from stores, people being murdered left and right. Deaths and disappearances are increasing, children are three times more likely to go missing now than 10 years ago. One out of six people have found or will find a dead body before they turn thirty. Mutilated bodies are hanging from trees, people's organs being ripped out and stuffed into bags back into their bodies. That person, climbing into your window, is linked to these murders."

The room started to spin around Undyne as she stared down at the picture with trembling hands. Why was it freezing? Her body felt stiff, her joints aching. The picture in her grasp was held tightly, as if it was her life line.

"Have you ever heard of CreepyPasta?"

Undyne almost fainted.

"I... a girl... told me about it..." Her voice was forced to muster, barely above a whisper. "That... it was a creepypasta... w-wasn't it...?"

The woman gave a remorseful nod. "It was. I had a feeling you were aware of their existence."

There was a CreepyPasta in her house.

There was a serial killer in her house.

Who targeted her specifically.

Sans was with a CreepyPasta before, multiple of them.

He knew where she lived.

He hated them.

He wanted them dead.

This wasn't bad luck, it was revenge. Sans wanted all of them dead, rightfully so, and this was his revenge. The blood came from this man, Sans sent him on purpose. But the government wouldn't know about it, right?

"Does Mr. Font have a brother?"

Undyne almost screamed, her throat dry and her hands too cold. The paper was digging under her scales, but it was long forgotten, instead replaced by the whirlwind of chaos in her mind.

"He... an older one..." Undyne said.

The woman nodded, looking sadly at the female in front of her. "And he's been missing, hasn't he?"

When Undyne's house had burned down, and she had to stay with Sans and Papyrus until they could move to the surface, Undyne had to sleep with Papyrus in a bed. After three nights, she moved to the floor, unable to sleep in the same bed with a skeleton. His bones would stick out, digging into her muscles in the most uncomfortable ways. That's how the metal chair she was sitting on at that moment felt, cramming into her from every angle.

"He has." She almost threw up.

"We believe he's been associating with them. Before he left, was he involved with them in any way possible?"

"W-We saw a couple with him."

Nodding, the woman pulled out another folder. Undyne felt guilt about the past year creeping up her back, almost consuming her whole. She was dumb, so dumb, she had made so many mistakes. Maybe she could plead for Sans, tell them that Sans wasn't a CreepyPasta, he was just a normal guy. He never killed anyone, he was just with them.

"As we suspected," She said, "I'm sorry to say, but..."

Please don't do it, please don't do it, please don't-

"Sans was kidnapped by the CreepyPasta."

What?
