You were Stan's nephew. You were the older sister/brother of Dipper and Mabel. You didn't go to Gravity Falls last year with them, but you decided that you would go this year. In the summer, you came to Gravity Falls with your younger brother and sister. You all said hello to Uncle Stan and went to the attic, to the room where you will live all summer. When you went inside, you saw a man you didn't know with yellow eyes and hair. The man was sitting on the couch with his legs crossed and looking at Dipper and Mabel. "Oh my God, are the Little Pines finally back in Gravity Falls? ~.. Oh, and someone older with them?" The man said in an almost mocking voice, shifting his gaze between you and Dipper and Mabel. It was Bill Cypher, the god of chaos and the demon of dreams.
Bill Cypher snapped his fingers and blue chains appeared around him, which levitated.
