Riley walked through the halls with a slight smile. He was excited to see Winter as usual. When he saw Winter though, something was off. All the alarms in his head were ringing. Riley approached Winter and spoke softly, "Hey Winter, how are you doing?" Winter looked at him and smiled. She then replied "Oh hey, I'm doing good!" Something about her outfit and everything in general still felt off to Riley, despite Winter responding in her usual cheery way when she sees him. "Wanna meet after school? I got to hurry to class and you should too," Riley said. Winter nodded and walked away, "See you after school then!" The day went by faster to Riley but that was probably because he wasn't really paying attention. Before Riley realized it, it was the end of the school day. Riley walked outside where Winter was waiting for him. "Do you wanna talk about something?" Winter asked curiously. Riley nodded and gestures for her to follow him. Every now and again he'd glance back at Winter and spot what appear to be bright yellow cat eyes. They then finally stopped at a secluded place. Winter's smile immediately faded once they stopped and when Riley turned around she had those glowing, bright yellow cat eyes. Her voice also sounded different when she spoke, "You figured it out pretty quickly, tiny sapling." Riley glared at her, realizing it was definitely not his Winter. His voice was stern as he spoke, "Who are you and what did you do to Winter?" Whatever was controlling Winter's body reached into her pants pocket and took out a knife. "I'm not going to answer your questions yet... I kinda want to see you writhe in pain as the one you love starts tearing into your flesh," they said. Riley flinched and recoiled a bit in terror. He tried to keep a stern voice but it wavered a bit, "You aren't Winter..." They suddenly charged at Riley, knife in hand, knocked him over, and pinned him against the ground violently. Riley groaned as his back was now hurting. They pierced the knife into Riley's left shoulder causing him to wince loudly. They kept him pinned down and started to drag the knife down his left arm. Riley started squirming and writhing in pain but he couldn't fight them off. They removed the knife from his left arm before piercing into his right shoulder. He glanced up and saw a sick, sadistic grin spread wide across their face. "G-give me back Winter and tell me who you are..." Riley pleaded weakly. Their expression shifted and they spoke, "Very well. Name's Bill Cipher! I'll probably occasionally take control of this Winter girl or maybe even you, tiny sapling." Cipher grinned at Riley before pulling the knife out of Riley's right shoulder. "Anyway, guess I should probably give you back Lil Miss Darkness here. Adios and hope to see you again soon!" Winter's eyes closed and she collapsed right on top of Riley. Riley gasped softly and ran a hand through her hair. She weakly opened her eyes and looked up at Riley. When she spoke her voice sounded normal but groggy, "W-what hapened?" Riley sighed softly and spoke gently, "I'll explain it to you eventually..."
