Why he is the way he is

It was a cold dark, damp night in the Hogwarts school dungeons. There
3 young students found him. Two; a boy and girl with jet black
hair, the other; a girl with light brown hair and a strand of white on
each side of her head. The man glared at them as they entered. The
girl with black hair raised the candle she held in her hands;
illuminating the corner where he was huddled with tears still flowing
from his dark, hate filled eyes. As the girl moved closer, he flinched
from her touch. She knelt besides him, the other children stood behind
her. The boy looked unsure of what was happening and the brunette
looked deep in thought. The black haired girl gently removed a crumpled
muggle photograph from her hands. She looked at tit then up at him, her
bright green eyes wide with curiosity and concern. Her voice was gentle
and light. She spoke in the way you would speak to a small child.
