Later, when you were alone, Dipper told you that it was Bill and he tricked Dipper into reading a spell to return. At first, surprisingly, everything was calm, not counting the sadistic jokes and mockery of you and passers-by. You tried to limit his powers with an amulet while he was sleeping, but he woke up and you achieved nothing. Of course, he was angry about this and summoned one of his old accomplices into this world. The pink demoness created chaos in the city and settled in the Northwest mansion.
