Frisk got to play around with her new camera that she got as a birthday present from the day before. Taking pictures of herself with all the monsters in Snowdin, and having a nice cinnamon bunny on top of it. It seemed like a normal day, until Frisk remembered what Gaster said about Sans's room. She walked back to the brother's house for dinner, coming up with a plan. That evening, while Sans was reading Papyrus his bedtime story, she went to check if San's room was unlocked. She went to his door and saw, lucky enough, that it was. Frisk sneaked inside, careful not to alert the two brothers. She was quick with navigating the room, stealing the silver key, and leaving without anyone noticing. She had a lot of practice with Papyrus's many puzzles. As she made her way downstairs, she was suddenly told to stop. "what are you doing up so late, kiddo?", it was Sans. He was on his way back from Papyrus' room. "I was uh, just getting a glass of milk before bed. I was so excited about all the things we're going to do tomorrow, that I couldn't sleep!" Frisk improvised. "fair enough. just make sure not to make too much noise. m'kay?" Sans replied. "I got it." Frisk answered, relieved that Sans believed her. "thanks, 'night Frisk" Sans finished as he calmly strolled to his room. Frisk let her sigh of relief go. Even though she was rarely one to lie, she was always afraid of the kind of punishment she would get for lying. Even when the brothers never got really mad at her. She wondered if going to sleep now would let her see Gaster again. After a bit of mental bickering, she decided not keep her hopes up for now and find these "clues".
Snowdin must be very cold at night, Frisk thought. So she changed from her pajamas to her purple and blue sweater, black trousers, and black sneakers, as she made her way outside. It took her a while to figure out that the basement was behind the house. And when she found the door, it was a circular hatch, rather than a normal cellar door. It took a lot of strength for Frisk to open the door. Probably because it was rusty from lack of care. As she slowly climbed down the basement ladder, she could see more and more of the room. Which looked a lot more like a laboratory or a workshop than the kind of basement she'd expect the brothers to have. But the strangest part was what was inside the room. There was a side counter with drawers and blueprints written in handwriting Frisk couldn't understand. there were also different items in each of the drawers. Like a badge that looked more like a compass, a photo album of people that Frisk didn't recognize, and a poorly drawn picture of three smiling people with the written words "don't forget". This was all very confusing to Frisk. Why did Sans own these? Why didn't he tell her about it? What made Gaster think that she would learn more about sans by finding this room? Frisk was about to leave before she noticed the large, purple curtain. She edged closer to it, with a feeling of dread building inside her, before nearly ripping the curtain off its hinges.
What Frisk saw, or at least what she think she saw, was one of the single most disturbing things she would ever know.
It was covered with blood. The Machine was cracked open, much like a skull, with what seemed to be rotting entrails inside, along with several broken bones strewn about. The stench of death filled Frisk's nostrils, and it was enough to make her vomit. As she stared at the scene before her, it felt like everything in the world was wrong, that the world was a terrible place, that she couldn't trust the ones she thought was family anymore, all in one moment. Then, she realized that the blood was... moving, reaching out to her. She could hear a faint, raspy voice calling her name. It became louder, and louder. The blood covered the entire room, even the walls and the ceiling, as it reached up at Frisk. The voice seemed to screech in her ears, as if it was intending to make her ears bleed. Frisk screamed her lungs out and she fled the workshop, a waterfall of tears streaming down her face, screaming into the night. As the horrific image dissipated into a black goo.
