snowmeat
Cycle 0: "Missing Girl" They kept them in a room, at first well ventilated and well kept, and fed them and made sure all waste was disposed of. She could hear her brother, muffled and quiet, through the thick cloth of her hood. They said it was her brother. She had no reason to doubt it. "You have to go inside." And so she went inside, and came out a little bit less human every time.
Cycle 1: "Little Sister" Trapped and quiet, talking in either riddles or hysteric repetitions of things she's heard. She tends to follow visitors around and observe them closely. She thinks highly of her BROTHer.
Cycle 2: “Meat” The apparent true form of little sister: a miserable, wretched little creature with no limbs. She talks more clearly now, but she is incredibly clingy and WILL attach to anyone who shows her a shred of kindness.
Cycle 3: "Snowmeat" Snowmeat just means corpse. Shed of all impurities and pain, she has become God.
