When Addyson woke up, light was streaming through the window. He saw me. He heard me. Oh, what trouble did I get Chara and the other girl into?
Chara and Frisk woke up shortly after each other. "Good morning" Chara yawned. Frisk hopped off her bed and made her way to the door. Addyson was nervously sweating, her eyes glowing purple. Chara noticed as she got off her bed. "What's wrong?" Chara asked her in Wingdings. "He saw me. He walked in and saw me with those small blaster things." She responded in Wingdings. "Who?" Chara asked worryingly. "The skeleton." She answered quickly. Chara's eyes widened as she turned to meet Frisk's gaze. Frisk's face had the what-trouble-did-we-get-into-now look, but she wiped off the expression as she left the room. Chara turned back to Addyson as she held out her hand. "Don't be scared. It'll be okay."
Addyson cowered in the corner of her cell. Gaster had walked into the cell, pushing his glasses up his face. He bent down and held out his hand to the girl in the corner. "Don't be scared. It'll be okay." His eyes were filled with kindness, his face cracked but caring. The girl took his hand and left the cell with him.
Addyson snapped back to reality and took Chara's hand. She let Chara help her up and lead her out of the room. They went down the stairs, being careful not to wake up Sans sleeping on the couch. They sat at the Dining Room table while Toriel and Papyrus made breakfast in the kitchen. Flowey was in-between Frisk and Chara's seats on the table. Flowey leaned into Frisk and whispered. "I think one of you three are in trouble with Sans. He seemed pretty jumbled up after he checked in on you guys last night." Frisk straightened up when he said this, sweating a little. Chara had overheard and looked worried, but she wiped the expression off her face once Toriel put a Bacon and Cheese Omelet on her plate. Once she put toast with butter on the side of her plate, Toriel asked the girls a question. "Did you all sleep well?" "Yes." Chara and Frisk responded while Addyson nodded. Frisk had pancakes with maple syrup and butter on top. Frisk dipped her crispy bacon into the maple syrup while Addyson ate a bowl of oatmeal. "Thank you, Toriel." Addyson said in English. Frisk and Chara quickly looked up at her, shocked. "You're welcome, child. Oh! I never quite caught your name. What is it?" Toriel beamed. The girl smiled. "Addyson." Chara saw her eyes spark green, but she seemed to control it. Once Toriel turned back to the kitchen, Flowey turned to Chara. He asked, "Why was it such a surprise that she said something in English? I couldn't help but notice you two's expression." Chara straightened up at this question. "I dunno. She just hardly talks." She responded quickly. Flowey looked like he had questions, but he kept his mouth shut. Chara, Frisk, and Addyson pushed in their chairs as they left the table. Outside of the dining room, Sans was waiting by the doorway. "could i ask you three something?" He asked. His pupils had disappeared, leaving his eye sockets to give a serious look. "S-sure." Chara replied. They all took a seat on the couch.
"can one of you give me a reasonable explanation as to why this addyson," He nodded to Addyson. "can summon gaster blasters and speak wingdings?" The four sat in silence for a moment. "No." Frisk replied hesitantly. Sans sighed. He inhaled and continued. "where did you even find her in the first place?" Frisk inhaled deeply. "Well, we were on our way home and there was this weird portal so we went to it and she popped out." Frisk said very quickly, all in one breath. "I think she somehow traveled through time and space." Chara noted. Sans looked stunned by this assumption. "where would that answer even come from?" He asked. "Well," Chara replied, standing up. "You would've heard of her before if she was a test subject- I mean-" Chara accidentally let it slip. Addyson's eyes widened. Sans looked very disappointed at the fact that they kept this a secret. He sighed once more. "we can't know that for sure. if she was, what was her subject name?" "Subject 17A." She responded in Wingdings. "He tried to use me to break the barrier. Before I knew it, I was behind a bush where Chara and Frisk found me." She said Frisk's name in English, which took some skill. Sans stood up, using his magic to turn her soul blue. When he saw it, he was alarmed. Her soul was half patience, two pieces of separate monster's souls forced together. This sudden action made Addyson panic, as she could not move. The other two parts of her felt in danger, so he only had a moment to observe it before she bursted with magic. Her face looked like the scientist's again, glowing white with no pupils. The pain was unbearable, like she was being ripped apart.
She was suspended in midair, breaking things around her. The two other parts of her soul tugged, the magic bursting outwards unstable. The scientist's face was full of curiosity and amazement. "Hahaha! They said it was impossible, they said it couldn't be done, but I've done it! I've had a breakthrough!" The girl was in sharp pain. Make it stop, make it stop! Her mind screamed. When it ended, she fell to the floor with a hard thud, making the world go dark.
Sans quickly stopped his magic, but the girl was still bursting with magic. She waited and waited. She was patient. It'll stop eventually. It always stops.
She was being torn apart from the inside, the two pieces of soul trying to escape. After a couple more minutes, it stopped. She was suspended in the air for a moment more, her face morphing back her her own. Her shirt, as everyone in the living room noticed, had changed. It went from her usual black sweater with two pink stripes to a pink shirt with one thick black stripe during her magic outburst. As she was midair for a moment longer, it changed back to her old sweater. She lost consciousness before she fell out of the air. Sans quickly used blue magic to make sure she didn't fall to the floor and gently rested her on the sofa. Everyone let out an exhale of relief and sat on the couch, careful not to sit on the unconscious girl. After a moment of awkward silence, Frisk asked quietly. "Please don't mention this to anyone else." "yeah, i won't." Sans replied.
