She is saved

Frisk couldn’t move. Her body was freezing, she couldn’t see. All she heard is what was around her. “Sans, look,” a voice said. “It’s a human.”

“Looks like the kid is dying, Paps,” Another voice, most likely Sans, said.

“She’s clearly an adult,” Paps said.

“I’ve lived so long everyone feels like a kid to me…” Sans replied. “Let’s take her back home.”

“Yes,” Paps said. “Then I can give her off to Undyne and save monsterkind. Then everyone will know The Great Papyrus is the hero we needed!”

Frisk woke up in a large prison cell with wooden bars. She felt much warmer. She looked up to see a tall skeleton dressed in one of the most ridiculous outfits she has seen. “Who are you?” She asked.

“The Great Papyrus,” the skeleton replied. “And you are my prisoner, human!”

Frisk looked down. “How do I survive the snow? I hear the barrier prevents humans from wearing clothes…”

Papyrus shakes his head. “You will be out of here when Undyne gets here!”

Papyrus left, Frisk saw another, shorter skeleton, in the corner. He wore a blue sweatshirt, black shorts, and pink slippers. “Sup, kiddo,” he said.

Frisk blinked. “Who are you?”

“Name’s Sans,” Sans said as he stuck his hand out for a handshake.

Frisk shook Sans’ hand and there was a long, loud, fart. Frisk stood there in shock before Sans started laughing. “Gotcha there, didn't I?”

Frisk walked up to the bars, she then walked through as she realizes the size of the gap. “How do I get through the snow?” Frisk asked. “I need to get home.”

Sans nods. “Come with me, I’ll help you out.”
