You are Dipper Pines girlfriend. It was in the middle of Gravity Falls summer, and it was very hot. You went to the Mystery Shack, you heard random noises like hysterical laughter but you don't question it. You walk inside to see dipper, but he was doing something weird with his hand, almost smashing it into something. You got concerned so you went up to him, kissing his cheek and rubbing his back. Bill immediately froze, he possessed dipper's body (not knowing about you)
