Ok so we all know how Jack got his powers, Right? Jack has a younger sister who disappeared after he got his powers. This fanfiction is on how she came back.
Jack walk away feeling great. He had sent Pitch away, all the children of the world were safe, and he had gotten his memories back. He remembered all of the fourteen years of his life he was a human. His thoughts were broken when he heard a small voice behind him.
"Jack?".
He spun around staff at the ready but, surprised to find a twelve year old girl almost dropped it. The girl had pale skin (much like Jack's), white hair (much like Jack's), and bright blue eyes (much like Jack's). She wore no shoes (or socks for that matter), she wore a dark blue sweater, and a pair of scruffy jeans. But what surprised him the most was that in her small, pale hand she held a silver dagger.
"Jenny?".
Then Jack heard inside his thoughts the MIM say "Congratulations Jack. Here is your prize."
