Sans awoke to darkness, It's probably midnight... he thought, rolling over. He didn't feel sleepy, but he didn't feel like getting up. He could see a little bit of the dark room that was cloaked in shadows. He closed his eyes again, trying to fall back to sleep despite not really feeling tired. Sans didn't really want to deal with Alphys lecturing him about walking around while he was healing. But something started nagging at him, telling him to get up. He sighed, and sat up, looking over the dark place. He got off of the bed, and let his eyes adjust to the darkness a bit better before walking around. When he got near the entrance area, he heard something that sounded like scratching. Sans didn't exactly know where it was coming from, he tried to listen, but it stopped shortly after his footsteps ceased. He decided he'd better go back before Alphys wakes up, he started heading back when he heard a whine. Sans turned around, it was coming from inside the walls. But how was that possible? Another whine echoed, he examined the room for an entrance of some sort. He saw a door, it looked like it was supposed to be a bathroom, but he walked over to it. The scratching was louder, he stopped in front of it, it whined again, then he heard footsteps, Sans waited until they were gone before slowly opening the door a little. It wasn't a bathroom at all, and he knew what this place was. It was the old secret lab, he looked around, hearing dripping noises. He was surprised that they didn't destroy this place after Gaster disappeared. Sans started exploring the area, having memories of his family, before it was torn apart. He was trying to remember where the hidden house was located. He knew it was somewhere around here, there were all of the entries up on the walls, some of the screens were shattered. Spider webs were in almost any corner, water was leaking from cracks in the ceilings and walls, the more he walked around, the more depressed he felt... The realization that the underground was really falling apart hit him, this place was old, it could collapse at any moment. When he came to a room with many worn beds in it. A few were missing blankets, others pillows, some having only the sheet, and the rest were bare.
Sans sighed, trying to find what was scratching at the door, he came across some open books that were left out, but he didn't bother reading them. Walking around for a little longer, studying the cracks in the wall, he came to one wall that had faded claw markings scratched on it. He carefully placed his hand on the wall, it opened up to show the old house. Sans's eyes widened at the sight, he hadn't been here in years, it was a mess. The wallpaper was slowly rotting off of the walls, the one soft chair Sans used to sit in was torn and it was on its side. Papers and many books with pages ripped out were scattered across the floor. Sans took a few step forward and heard a crunch from under his foot, he looked down and saw an old picture of Gaster, Papyrus, and himself. Sans took his foot off of the photo and crouched down, carefully picking it up and brushing off broken shards of glass. Gaster was hugging Sans and Papyrus with a warm smile on his face, Papyrus had his eyes closed while he was tightly hugging Gaster, and Sans was looking at the camera with a cheerful smile. He sighed sadly at the photo, he missed those days, when he didn't have to worry... Sans stood up and took the photo out of the broken frame, he placed the photo in his pocket and walked into the kitchen. Stains were splattered on the walls, Sans found some old pots and pans lying around on the ground or on the counters, and some of the cabinets were open. He walked back into the main room and walked into the workroom.
A computer monitor with a crack in the screen sat on the desk with a keyboard in front of it, the keyboard was dusty, but it had no keys missing. Beside the monitor, there was a sloppy stack of papers, and some of the papers were littered around on the desk in random places. Sans looked to his right and saw a filing cabinet, he walked over to it. It had three cabinets total, the bottom one was open and some of the files had been taken out, now on the floor, the rest sat in the cabinet in a disorganized pile. He opened the middle cabinet to find it was empty, with only a sticky note that said, "Missing." Sans opened the last one and found the names of monsters he recognized, he took a random file out. Sans saw that it was his, his eyes widened, he opened it to find it all scribbled out in pen, his age, his description, his birth date, his height, his weight, and even his guardian was crossed out. Sans put his back and grabbed another one, it was Ms. Hermosa's, he opened it and found no serious information on her. He wondered if she was doing ok even to this day, he hadn't seen her since... Sans closed the file and put it back, closing the top filing cabinet and walking into the hallway. It was dark, the emergency light was busted, he walked through the dark, the light of his father's lab was his only lead. That was when a low growl emitted from somewhere nearby, and he heard a familiar voice. "You showed me here! Where's Sans?" It was Alphys, he didn't know how to react, he walked back toward the workroom cautiously, when he heard something loud barrelling towards him. Sans jumped back in alarm when an odd creature tried to ram into him, it hissed when it hit the wall and shook its head. He stepped back when it made eye contact with him, despite the darkness, it glowed like echo flowers in a multi-color pattern. Red, orange, yellow, green, light blue, royal blue, purple, and pink cut through the darkness. It had eight eyes, all a different color, its body appeared to be black, it had some sort of circular tank on its chest, storing something that was the colors from red to light blue, the outside surrounding it was royal blue. It had pink claws, a black tail with a spiked pink end, and on its side, there were two tubes on either side holding purple liquid that had claws that dripped the purple substance at the end.
The creature's claws slashed at Sans, getting his chest and his forehead, it stung worse than any normal wound. He stumbled backward and cupped a hand over his chest wound, using his other hand to balance himself, he looked up at the beast. It growled lowly and struck at his head again, Sans swiftly dodged, but it made the pain worse, he groaned and saw the light from the lab. The creature struck again and he blocked with his arm, he felt the substance getting poured into his veins, Sans growled and acted quickly, he kicked it away and took a sprint to the lab. It followed, he got inside and collapsed from the pain, the poison had taken effect quickly. The creature picked him up, he felt bone marrow start to escape his mouth. It turned him so that he would be looking directly into its eyes. Sans struggled in its grip as he held him there, the poison was starting to make him dizzy. The creature threw him into a wall, he was winded from the impact. Sans lay there as the creature approached him, he tried to catch his breath, his body was burning, but he needed to get away. It growled and whacked him sideways, causing him to gasp in pain. He tried to get up, heaving from exhaustion. Sans managed to get to his feet and stumbled away, barely dodging its attacks. He got out of the lab and gathered enough strength to run down the hallway, he ran into the main room and saw Alphys. She seemed like she had been knocked out, Sans quickly picked her up and ran into the true lab, hearing the creature running after him. The poison was starting to affect the way he walked, he tried to focus on finding a way out. Finally, he found the exit, he felt something stab him in the back, he cried out in pain as it lodged in his ribs. Sans fell to the ground, Alphys awoke, "Sans?! A-are you ok?!" Sans realized she still had a chance. "Alphys! Get something to knock this creature out, don't let it touch you!" Alphys got to her feet and scrambled away, leaving Sans to deal with the pain of distracting this thing alone. He dragged himself over to a wall and used it to help himself get up. It stared daggers at him as he moved, but it made no move. Sans wiped some blood away from his face. The creature turned and ran for where Alphys went, he wanted to help her, but his strength was gone. Sans let himself fall, he lay on the floor, everything hurt. His vision was getting blurry, he was starting to feel cold, his eyes closed. Soon after, he lost his consciousness. He could hear echoing footsteps, whoever it was he heard light breathing, arms wrapped around him and lifted him off the ground someone picked him up...
...
Wilhelmina awoke to the sound of creaking, she wondered how long she had been out. She carefully peeked over to the entrance and saw someone carrying something, Wilhelmina stayed quiet, watching as they placed a body on the couch, then they stopped for a moment. They looked directly at her, she flinched, then they gestured her to come down. Wilhelmina was sure if she could trust them, but she carefully got up and approached the being. She could now see that it was like a female human, she had long, pastel purple hair that curled upwards at the end, gray eyes with cracked irises, and a cloak that covered the rest of her features. "Little one," the voice spoke softly, Wilhelmina looked up at her. "I need to leave, please tend to the wounds on this monster..." She smiled softly, "I hope you won't have much trouble, goodbye." The girl left, leaving Wilhelmina with an injured skeleton she didn't even know. She sighed and started to carefully look for anything to clean and bandage his wounds, Wilhelmina didn't know much, but Toriel was teaching her which herbs would help with different wounds. She started looking through cabinets, eventually, she found some fresh bandages and some alcohol for cleaning wounds. Wilhelmina heard some shifting and looked into the living room to see the skeleton was awake. She made eye contact with him and they both froze, the skeleton seemed to be shocked. She made her way over to him, he seemed to try and back up, but she shook her head, letting him know that she wasn't there to hurt him. He stayed still, Wilhelmina sat next to him, then she hesitantly started to take off his jacket and sweater. Once she did so, she carefully took a washcloth she had found and poured the alcohol on it, then she started to clean the wound.
The skeleton grunted in pain and clenched his teeth, she tried to get as much of the weird purple substance leaking from the wound as possible. Then she moved to his forehead, repeating the process, and then his arm. Then she looked at the spike that was lodged in between two of his ribs, it was digging into them, she had to get it out without hurting him more. Wilhelmina lightly pushed on the spike, earning a whimper from the skeleton. She pulled away and looked down, wondering how she was going to do this properly. The skeleton reached out and pulled her closer, "Get it over with..." He whispered. She carefully closed one of her hands around the spike and started to push it. The skeleton bit his lip and shut his eyes, very slowly, she pushed it out, making sure to stop every few seconds. Once she got it out, she saw the damage that had been done. part of his ribs was cracked and bleeding in the front, but in the back, the spike had broken parts of his ribs off, and it was bleeding very badly. She gasped and covered her mouth, tears filling her eyes. "Hey... Don't cry... I'll be fine... Just clean it up..." She listened to him and started cleaning the wound carefully. He grimaced in pain and buried his head in the couch cushion, Wilhelmina was glad he was holding still while she tended to the wound. She finished and he sat up, she started bandaging all of his wounds. She sighed when she was done, the skeleton put his sweater and hoodie back on. Wilhelmina wanted to ask some questions, but she didn't know if the skeleton knew sign language, and she wasn't very good at it either. "My name is Sans, what's yours?" Wilhelmina signed her name slowly, Sans seemed to understand. "Wilhelmina?" She nodded, he lay down beside her, Wilhelmina wanted to hug or comfort him. She didn't like seeing people hurt, she decided against it and sat there in silence. Sans noticed and sat up, "What's wrong?" Wilhelmina looked at him and shook her head, Sans scooted over to her and put a hand on her shoulder. "If you think I'm going to hurt you, I'm not, you might be a human, but you helped me with my wounds when I was weak. You had the chance to kill me, instead, you helped me, Wilhelmina." She shivered slightly when she heard her name. "I know that some monsters want to kill your kind... I'll protect you..." Wilhelmina nodded and hugged Sans, he stiffened up a little, but he wrapped his arms around her. Wilhelmina wished she could thank him properly, she had just snuck into his home, and now he was offering to protect her from other monsters. She wanted to speak... She felt something that told her to speak... "Thank you..."
