One Last Deal

Andrea "Andie" Wilson-Pines is a young girl with a mysterious past. She never knew her father, her mother left her at the Pacific Northwest Orphanage when she was a baby...and her grandfather...she doesn't talk much about him. All she knew was the orphanage and her brothers...until she met Dipper and Mabel.

Upon meeting and befriending Andie in the woods, Dipper and Mabel convince Stan to have the young girl stay with them in the Mystery Shack. However, Andie is hiding a secret bigger than they could ever imagine.

Remember, in Gravity Falls, there is no one you can trust.
