You were hired by Jade to look for a kid in that dump; she didn't like getting her hands dirty too much and had decided to ask you directly since you were the mind and you were the strength. From the description he gave you and a little drawing you were looking for a boy with blond hair and slightly neon eyes, he had a mark on the left side of his neck (seen from the front), a chain around his neck and some dirty rags like clothes
After about two hours of wandering around that maze of cells and rooms and corridors, you finally found him; you approached the cell and opened it (I leave your imagination free my dear ;3) and you approached the boy, who in the meantime raised his head and started looking at you with those empty eyes. You extended your hand to him, as if an invitation to take it but he looked at you as if to understand whether he should trust you or not
