(Gun mention, death, child abuse)
Bullet
Harry had never learned how to use a gun. Hell, he barely knew what a gun was, growing up, except that it went boom! and the people on telly fell dead from the tiny thing.
Still, he knew they were dangerous, and that they could kill. He never wanted to touch, much less use one.
But when his Uncle hit him too hard one day, just at his second year of Hogwarts, Harry's magic did a swish and a BANG and Vernon fell, dead.
Harry didn't know much about guns, no, and he knew his magic had killed Vernon in self defense. But every time he closed his eyes he saw the small entry wound in his Uncle's chest, bleeding red.
He went to live with the Weasleys, Molly opening her arms and embracing the abused boy to her bosom. Harry grabbed onto her, shaking, and never wanted to let go.
